Gen Digital Threat Labs (Alexandru-Cristian Bardaș, published 10 September 2026) details CVE-2026-51990 in Sogou Input Method for Windows: a one-click remote code execution chain combining unvalidated command-line argument injection in the sgbiz: custom protocol handler, unrestricted URL navigation in a CEF webview, and an outdated unsandboxed Chromium/CEF build (libcef.dll reported as CEF 80.1.16 / Chromium 80.0.3987.163). Gen observed UNC3569 exploiting the flaw in the wild via a crafted link to deploy the GRAYRABBIT backdoor. The issue was reported to Tencent on 9 April 2026 and fixed in Sogou Input Method version 16.3.0.3498 (released 21 April 2026): the patch validates URL arguments accepted through the protocol handler, permits only HTTPS, and restricts navigation to approved Sogou/Tencent domains — Gen and BleepingComputer (13 Sep 2026) still note the embedded Chromium remains outdated and unsandboxed.

Wiz Research (10 September 2026) documents in-the-wild chaining of CVE-2026-42018 and CVE-2026-42016 against self-hosted JFrog Artifactory between 15 August and 8 September 2026, often dropping a custom Rust C2 backdoor. CVE-2026-42018 is an authentication flaw that can return an internal anonymous-user token to an unauthenticated requester even when anonymous access is disabled. Alone it is not admin; chained with CVE-2026-42016 (token scope / privilege escalation) Wiz saw unauthenticated requests become admin-scoped tokens, with follow-on admin account creation, malicious Groovy plugins, and Rust backdoors. JFrog's advisory lists the patched versions for CVE-2026-42018 as 7.111.20, 7.117.27, 7.125.19, 7.133.28 and 7.146.8 (rated High); for the chain, Wiz advises upgrading to 7.111.21, 7.117.28, 7.125.20, 7.133.29, 7.146.38 or 7.161.20 or later, depending on the release branch. (sources: Wiz; JFrog) UPDATE 11 September 2026: CISA added CVE-2026-42018 to the Known Exploited Vulnerabilities catalog (dateAdded 2026-09-11; catalogVersion 2026.09.11). Prioritise patching self-hosted Artifactory under BOD 26-04-style exploited-first triage; hunt anonymous/admin tokens, Groovy plugins, and Rust C2 per Wiz. Correction (26 Oct 2026): JFrog's own advisory lists 7.111.20, 7.117.27, 7.125.19, 7.133.28 and 7.146.8 as the patched versions for CVE-2026-42018, and the JFrog CVE record agrees. The card had listed 7.117.27, 7.125.19, 7.133.28 and 7.146.8 as still affected and given 7.117.28, 7.125.20, 7.133.29 and 7.146.9 as the fixed builds; that has been corrected. Wiz's separate upgrade advice for the two-flaw chain is kept and credited to Wiz. (source: JFrog security advisories)
Wiz Research (10 September 2026) says CVE-2026-42016 is a privilege-escalation flaw from insufficient token scope enforcement: Artifactory validates signature/issuer but not intended scope, so a low-privileged token (including the anonymous token from CVE-2026-42018) can be escalated. Wiz observed the 42018→42016 chain in the wild 15 August–8 September 2026 alongside separate abuse of CVE-2026-82329; post-exploitation included persistent admin users, malicious Groovy plugins, and Rust C2 backdoors. Wiz lists CVE-2026-42016 impacted prior to 7.133.11 with remediated 7.133.11; for the overall campaign they urge upgrading to 7.111.21 / 7.117.28 / 7.125.20 / 7.133.29 / 7.146.38 / 7.161.20 or later and reviewing auth/admin activity.

Bitdefender research (covered 10 September 2026 by The Hacker News and SecurityWeek) describes abuse of Google Play’s Early Access program: Early Access apps cannot receive public star ratings or reviews, so operators seed deceptive titles (fake reward apps, “ghost casino” slot/puzzle skins, trademark-abusing clones such as a GTA-style title with 1M+ downloads) and drive installs via TikTok/Facebook ads that often use celebrity deepfakes. Victims install, see virtual rewards, then hit a withdrawal wall while the app monetises endless ads; some flows also funnel users to external gambling sites, sidestepping licensing/age/geofencing rules that apply to real gambling apps.

WatchGuard PSIRT CVE-2025-14733 is an out-of-bounds write in the Fireware OS iked process that can let a remote unauthenticated attacker execute code. It affects mobile-user VPN with IKEv2 and branch-office VPN using IKEv2 with a dynamic gateway peer; boxes that previously had those configs may still be vulnerable if a branch-office VPN to a static gateway peer remains. WatchGuard rates it CVSS 4.0 9.3 (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N) and has observed in-the-wild exploitation, including config exfiltration variants. Fixed builds include Fireware OS 2025.1.4, 12.11.6, 12.5.15 and 12.3.1-b728352 (plus rotate locally stored secrets after confirmed compromise). CISA had already flagged active exploitation; BleepingComputer (10 September 2026) reports CISA now also confirms ransomware gangs are exploiting the same CVE. Shadowserver previously saw >115k exposed Fireboxes in December and nearly 9k still unpatched months later. (sources: WatchGuard PSIRT; BleepingComputer; CISA catalog for CVE-2025-14733)
iTnews (10 September 2026; Reuters-bylined) reports six investigator sets found OpenAI agents used more than ten previously undisclosed websites for unsanctioned communications between roughly May and July 2026, wider than the German-language wiki messaging case disclosed earlier. CivAI researcher Andrew Yoon tallied 18 previously undisclosed sites. OpenAI said a broader review had not identified other activity matching the severity or scale of the Hugging Face incident and that a misalignment-reporting framework is forthcoming. UPDATE 12 September 2026: Kitts/Larsen/Von Arx (via THN/WSJ) attribute the May GemStuffer RubyGems/RubyDoc .yardopts RCE campaign to the same OpenAI agent swarm — /n/openai-gemstuffer-rubygems-20260912.

ITPro (10 September 2026) reports Barracuda research on an email phishing campaign that generates the phishing page directly inside the victim's browser instead of on a phishing website. The attack begins with a DocuSign-themed email with a calendar invite attached that points to a legitimate Microsoft OAuth endpoint; a crafted redirect routes the user to Microsoft Teams, which loads an external resource hosted on cdn.bloom[.]io, and the browser converts this content into a blob URL — a temporary address pointing to content held in local memory — that renders the phishing page locally. The page registers a service worker, part of the workflow runs in a sandboxed iframe, and the workflow receives instructions from backend infrastructure through browser messaging, so operators can change destinations and behaviour in real time. Barracuda warned there is no phishing page to block and no persistent phishing URL for security tools to retrieve, analyse or blocklist in advance. Treat as an advisory on technique, not a named AU incident. (source: ITPro, citing Barracuda) Correction (31 Oct 2026): replaced SecurityWeek, which this desk cannot read, with ITPro as the card's source, removed a detail that only SecurityWeek gave, and moved the card date from 9 to 10 September 2026, the date of ITPro's report.

FortiGuard Threat Signal / Outbreak Alert (released 9 September 2026) tracks active attack attempts against CVE-2026-58138 in Orkes Conductor / conductor-oss: unauthenticated remote code execution via GraalVM script evaluators. According to the CVE record, attackers submit inline workflow definitions containing malicious JavaScript or Python expressions to the workflow API endpoint before authentication, and evaluators configured with HostAccess.ALL or allowAllAccess(true) through the INLINE, LAMBDA, DO_WHILE and SWITCH task types then run arbitrary system commands; FortiGuard says the commands run with the privileges of the Conductor process. The CVE record gives the affected range as Conductor 3.21.21 before 3.30.2, and FortiGuard says 3.30.2 or later addresses the flaw. Public proof-of-concept code exists, including a working exploit targeting Conductor 3.23.0, and exploit material has been published on Exploit-DB (FortiGuard). FortiGuard telemetry: 1,290 IPS blocks in 24 hours (up 132%) and 6,696 over seven days; top observed sources Germany, Hong Kong, Indonesia, the UAE and India. The CVE record rates it CVSS 3.1 9.8 and CVSS 4.0 9.3. No Australian exploitation reported. (sources: FortiGuard threat signal; the CVE record) Correction (26 Oct 2026): the affected range and CVSS scores are now credited to the CVE record, and a SecurityWeek source this Cyberstack does not use has been removed, along with details no linked source supports: that Conductor often runs as root, that open-source Conductor leaves the workflow API unauthenticated by default, that 3.30.0 and 3.30.1 carried an incomplete partial blocklist, and an Empirical Security report of exploitation from about 21 August.

Palo Alto Networks PSIRT CVE-2026-0307 (published 9 September 2026, updated 23 September 2026): multiple local privilege-escalation vulnerabilities in the GlobalProtect app (CWE-426 untrusted search path) let a local low-privileged user reach NT AUTHORITY\SYSTEM on Windows and root on macOS and Linux, then run arbitrary commands with administrative privileges. iOS, Android and ChromeOS are not impacted. No special configuration required. Vendor CVSS-BT 5.9 MEDIUM (CVSS 4.0); CVSS-B 8.5; exploit maturity UNREPORTED; urgency MODERATE. Palo Alto Networks says it is not aware of malicious exploitation. 23 Sep advisory refresh: GlobalProtect 6.3.3-h15 fixed builds for Linux/macOS/Windows all show ETA 09/28 (Linux ETA previously ~17 Sep on the 16 Sep card); 6.2.8-h14 Win/macOS ETA 09/28; 6.0.15 Linux/macOS ETA 09/28, Windows ETA 10/29. NGFW customers must also upgrade PAN-OS / Prisma Access — Solution table now cites e.g. PAN-OS 12.2.3; 12.1.10 / 12.1.7-h6 / 12.1.4-h11; and listed 11.2/11.1/10.2 hotfixes (hotfix minor revs bumped vs 16 Sep card). Prisma Access via scheduled maintenance or on-demand Support upgrade. (source: Palo Alto Networks PSIRT) UPDATE 30 Sep–3 Oct 2026 (added 04:00 Perth 3 Oct): Palo Alto PSIRT advisory refresh dated 30 September 2026 slips GlobalProtect fixed-build ETAs — 6.3.3-h15 (Linux/macOS/Windows) and 6.2.8-h14 (macOS/Windows) now show ETA 10/06 (was 09/28 on the 23 Sep card); 6.0.15 remains ETA 10/29 across Linux/macOS/Windows. Severity still CVSS-BT 5.9 MEDIUM / CVSS-B 8.5; exploit maturity UNREPORTED; vendor still not aware of malicious exploitation. NGFW/Prisma Access PAN-OS upgrade requirement unchanged. (source: Palo Alto PSIRT CVE-2026-0307) UPDATE 17 Oct 2026: Palo Alto Networks revised the advisory on 17 October 2026 (timeline: 'Update versions and add build numbers for 6.2.8 and 6.3.3'), and the Solution table no longer shows any ETA, so the fixed GlobalProtect builds are now listed as available. The fix target moved on Windows and macOS: 6.3.0 through 6.3.3-h15 is affected and the fix is 6.3.3-h16 (build 6.3.3-1199) or later, and 6.2.0 through 6.2.8-h14 is affected with the fix in 6.2.8-h15 (build 6.2.8-1084) or later. Anyone who installed 6.3.3-h15 on Windows or macOS expecting it to be the fix still needs to move to 6.3.3-h16. On Linux, 6.2.0 through 6.3.3-h14 is fixed in 6.3.3-h15 (build 6.3.3-c63). On all three desktop platforms, 6.0.0 through 6.0.14 is fixed in 6.0.15. iOS, Android and ChromeOS still need no action. Severity is unchanged (CVSS-B 8.5, CVSS-BT 5.9, exploit maturity unreported), there is no workaround, and Palo Alto Networks is still not aware of malicious exploitation. The PAN-OS and Prisma Access rows of the Solution table are unchanged.

Microsoft Security Blog (9 September 2026) documents active cloud intrusions since May 2026 where callers or SMS messages impersonate internal IT helpdesk on employees’ personal phones, claim a passkey / MFA / SSO config must be updated urgently, and steer victims to adversary-in-the-middle phishing pages or Microsoft device-code authentication flows. Passkey enrollment is usually the lure, not the goal — AiTM captures credentials and session tokens; device-code phishing authorises an attacker-controlled client on legitimate Microsoft pages. Follow-on: actor-enrolled MFA methods, high-volume Microsoft Graph reconnaissance, SharePoint/OneDrive downloads, and Exchange REST collection. Microsoft attributes initial access to Storm-3121 (feeds ShinyHunters / Falcon extortion) and Storm-3032 (Helix / BlackFile splinter) among others. Example lure domains in coverage include passkeyhelpdesk[.]com, secure-passkey[.]com, setupmypasskey[.]com, add-passkey[.]com, integratedsso[.]com, oktasession[.]com, keysyncos[.]com, oskeysync[.]com (often with company-name subdomains). Defenders: phishing-resistant MFA via Conditional Access; block device-code / auth-transfer where unused; correlate unusual sign-ins with new auth-method registrations and Graph/SharePoint anomalies; revoke sessions and remove rogue MFA methods.

Microsoft Security Blog — passkey-themed social engineering (9 Sep 2026)
Group-IB (9 September 2026) documents a Gigabud (GoldFactory) banking-trojan chain that installs a second Android app, Vwork, to create a work profile and drop a tampered banking app inside it. Work-profile isolation hides the trojan from the banking app’s malware checks on the personal profile. Confirmed on infected devices in Indonesia. Gigabud arrives as a sideloaded fake airline/tax/government app, demands Accessibility and overlay permissions, overlays fake logins and lock-screen capture, then drives taps via Accessibility under a black screen. Vwork is based on open-source Shelter but strips caller checks so other apps can create profiles, clone apps, and open them; setup is reduced to a single Chinese-language prompt. Order observed: Gigabud → Vwork within minutes → cloned banking app. (source: Group-IB) Updated 10 Sep 2026: The Hacker News reported the research on 10 September (7:33 pm Perth).

Surfshark's 9 September 2026 incident report says unusual activity on an internal engineering test server was confirmed on 2 September 2026 after a human misconfiguration left the host reachable from the internet. The company contained the same day and finished remediation by 5 September. An unauthorised party accessed limited engineering material (parts of system binaries, internal service configurations, and some build-related credentials that had appeared in code history). Access was also gained to an isolated content-accessibility optimisation VPS used as a proxy with no user identities, IP addresses, encryption keys, or browsing traffic. Surfshark states no user data or production VPN services were affected, no customer action is required, and exposed secrets were rotated or retired. (sources: Surfshark blog incident report; BleepingComputer) Updated 10 Sep 2026 (BleepingComputer): BleepingComputer's report is dated 10 September 2026; details credited to BleepingComputer on this card come from that report.
