Google's Stable Channel Update for Desktop (4 September 2026) promotes Chrome to 152.0.7977.82/.83 on Windows and macOS and 152.0.7977.82 on Linux with 12 security fixes. High-severity CVE-2026-85046 is a type confusion in V8 that Google says allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page; Google states an exploit exists in the wild. NVD Secondary CVSS 3.1 is 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). Salvatore Gulizia (Serotav) reported it on 4 August 2026. CISA added CVE-2026-85046 to KEV (catalog entry dated 4 September 2026). WA SOC advisory 20260907001 (7 September 2026, TLP:CLEAR) covers the same Chromium V8 type confusion for Chrome, Edge, Brave and Vivaldi prior to those builds, notes CISA KEV, and says it has not received reports of exploitation on Western Australian Government networks at the time of writing. Distinct from desk card chrome-firefox-20260902 (2 Sep Critical UAF batch at 152.0.7977.75/.76) and cve-2026-79290 (25 Aug Aura/ANGLE). UPDATE 9 Sep: Proofpoint BlueMoon exploit kit (desk card bluemoon-exploit-kit-20260909) chains this CVE with an un-CVE'd V8 sandbox escape and Windows CVE-2026-85880; APT31 first seen 28 Aug, then other espionage clusters. Update Chrome promptly; Chromium browsers (Edge, Brave, Opera, Vivaldi) should follow vendor builds.
Chrome Stable Channel Update for Desktop (4 Sep 2026)
Wordfence (via The Hacker News, 4 September 2026) reports active exploitation of CVE-2026-14894 in the WordPress plugin Super Forms – Drag & Drop Form Builder. NVD/Wordfence describe missing file-type validation on the unauthenticated submit_form AJAX handler (session nonce obtainable via a separate nopriv endpoint), allowing unauthenticated arbitrary file upload and remote code execution. Wordfence CVSS 3.1 is 9.8 Critical. Affected: all versions through 6.3.313; fixed in 6.3.314. Wordfence says it blocked over 250,000 exploit attempts against this CVE (plus ~190,000 against Elementor Pro CVE-2026-32475 in the same reporting wave; Elementor stays on its own desk card). Observed Super Forms attacks POST to /wp-admin/admin-ajax.php with action=super_submit_form and a Base64 PHP web shell disguised as a data:image/gif payload (e.g. Mushr00w_upl.php); activity began 14 July 2026 and peaked above 40,000 requests on 18 August 2026. Upgrade Super Forms to 6.3.314+; hunt unexpected .php under uploads; keep WAF rules current. Distinct from cve-2026-32475 (Elementor Pro).
ConnectWise ScreenConnect™ 26.6.5 Security Patch bulletin (8 September 2026, Priority 1 High) assigns CVE-2026-84869 for a client-side condition that may allow files to be transferred and executed through an active remote Support/Access session without authorisation or Host confirmation. ScreenConnect servers are not impacted. CWE-862 Missing Authorization / CWE-269 Improper Privilege Management; CVSS 3.1 9.9 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H). Affected: ScreenConnect versions prior to 26.6.5. Remediation: upgrade to 26.6.5 or later, then reinstall Host clients and update Access agents (Cloud servers already remediated per vendor). Interim mitigation until clients are refreshed: remove TransferFiles (and TransferFilesInSession on legacy) from applicable roles/session groups — not a substitute for the patch. Earlier 3 September Guest File Transfer Advisory and Huntress late-August worm-like rogue ScreenConnect client chain (Quick Assist → wscript → VBScripts / User Run Key) remain relevant context; Shadowserver has tracked thousands of internet-exposed instances. CISA KEV listed CVE-2026-84869 on 11 September 2026 (dateAdded 2026-09-11; catalogVersion 2026.09.11); this card remains the single ScreenConnect file-transfer topic. Distinct from faronics-deploy-screenconnect-20260831. Primary: ConnectWise 2026-09-08 bulletin.
Broadcom VMSA-2026-0007 (3 September 2026, Critical) patches two privately reported host-escape-class bugs in VMware Workstation and VMware Fusion 25H2 and 26H1. CVE-2026-59346 is a VMXNET3 integer overflow (CVSSv3 up to 9.3) where a malicious actor with local administrative privileges inside a guest that uses the VMXNET3 virtual NIC may execute code on the host. CVE-2026-59347 is an HGFS stack-based buffer overflow (CVSSv3 up to 8.1) that can let a guest admin run code as the VMX process on the host. Fixed in Workstation and Fusion 26H1u1. No workarounds. Broadcom does not report in-the-wild exploitation. Update lab and desktop hypervisors promptly; these are not ESXi/vSphere guest escape advisories.
Exploit-DB entry 52680 (dated 3 September 2026) and Metabase advisory GHSA-w95f-x9v9-wv36 cover CVE-2026-59827: Metabase instances with an H2 database connection (including the default sample database) deserialize arbitrary Java objects from native H2 query result columns of type OTHER without validation. An authenticated user who can run native queries against an accessible H2 connection can execute OS commands on the Metabase host. Affected ranges in the exploit write-up include ≥0.58.0 <0.58.15, ≥0.59.0 <0.59.12, ≥0.60.0 <0.60.6.3, and ≥0.61.0 <0.61.1.4. Patch Metabase; remove or lock down sample/H2 connections; restrict who can run native SQL.
Exploit-DB entry 52681 (dated 3 September 2026) documents a public remote-code-execution exploit for CVE-2025-57819 in FreePBX Endpoint Manager. The flaw is an unauthenticated SQL injection in the brand parameter of /admin/ajax.php that can insert a malicious cron_jobs row and yield a reverse shell as the web user. Affected branches per the exploit write-up: FreePBX 15.x before 15.0.66, 16.x before 16.0.89, and 17.x before 17.0.3 (title tested against 17.0.2). The write-up cites CVSS 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), CWE-89 and CWE-288, NVD, and GitHub advisory GHSA-m42g-xg4c-5f3h. Upgrade Endpoint Manager / FreePBX to the fixed releases; restrict admin/ajax exposure; hunt for unexpected cron_jobs entries.
The Hacker News (3 September 2026) reports researcher Chaotic Eclipse published FalconFlank, a public local privilege-escalation exploit demo that abuses CrowdStrike Falcon Sensor’s Office malicious-macros remediation path on fully updated Windows 11 25H2 and Windows Server 2025. The researcher said Falcon may already detect the demo code and that lab checks may need exclusions or obfuscation. A CrowdStrike spokesperson told THN the company is investigating, advised customers to disable the Microsoft Office File Suspicious Macro Removal Windows policy setting, said customers remain protected through Cloud Anti-malware for Microsoft Office Files, and pointed operators to the FalconFlank Tech Alert in the CrowdStrike support portal. Review the portal alert, apply CrowdStrike guidance, and treat the public exploit code as high-signal for endpoint labs.
BleepingComputer (3 September 2026) reports Hewlett Packard Enterprise patched a critical buffer-overflow remote code execution issue in ArubaOS-CX, tracked as CVE-2026-73749: an unauthenticated remote attacker can send crafted packets to an affected daemon and execute code with elevated privileges. HPE security bulletin hpesbnw05134en_us lists fixed builds by branch: 10.18.0001 → 10.18.1002+; 10.17.1021 and earlier → 10.17.1030+; 10.16.1051 and earlier → 10.16.1060+; 10.13.1180 and earlier → 10.13.1190+; 10.10.1180 and earlier → 10.10.1181+ (10.10.1181 is End of Maintenance and receives only critical internal fixes). The same bulletin covers about 23 further issues; Bleeping citing HPE places several authenticated management flaws (including CVE-2026-73750/73751/73752 and related) in the high range around 8.1–8.8. WA SOC advisory 20260909002 (9 September 2026, TLP:CLEAR) covers the same CVE-2026-73749 RCE (CVSS 9.8 Critical), lists the same fixed branches, and states it has not received reports of exploitation on Western Australian Government networks at the time of writing. Upgrade AOS-CX switches to the fixed release for your branch; restrict management-plane exposure until patched.
BleepingComputer (3 September 2026) and Wordfence (via The Hacker News, 4 September 2026) report active exploitation of CVE-2026-32475 in Elementor Pro for WordPress. Faulty validation of file-upload arrays in Elementor Pro forms (versions 4.2.1 and earlier) lets an attacker submit an empty first array element and a malicious PHP file as the second, so later files skip validation. The payload lands under /wp-content/uploads/elementor/forms/ and can be fetched to run commands. Elementor shipped 4.2.2 on 19 August 2026. Wordfence says it blocked about 190,000 exploit attempts against this CVE (and over 250,000 against Super Forms CVE-2026-14894 in the same wave — that CVE has its own desk card). Exploitation needs a published Elementor Pro Form widget with at least one File Upload field. Patchstack disclosed the issue earlier. Upgrade Elementor Pro to 4.2.2 or later; review uploads under elementor/forms for unexpected PHP; keep WAF rules current.
Marimo GHSA-2679-6mx9-h9xc / NVD: CVE-2026-39987 is a pre-authentication RCE in the reactive Python notebook server. The /terminal/ws WebSocket lacks auth, giving an unauthenticated attacker a full PTY shell. NVD: versions prior to 0.23.0 affected; CVSS 3.1 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H); CVSS 4.0 9.3 also published. Exploit-DB 52673 (2 Sep 2026) shipped a public PoC (cited ≤0.20.4). UPDATE 15 September 2026 (Sysdig Threat Research; THN wire): Sysdig observed a skilled human operator exploit this CVE within hours of disclosure, pivoting from Marimo to AWS Secrets Manager then an SSH bastion in eight seconds with a hand-rolled Python toolkit (850+ interactive commands over ~9 hours; source IP 172.236.12.17 on first WS connect). Upgrade to 0.23.0+; never expose Marimo terminal WebSockets to the internet. Primary: Marimo GHSA / NVD; research: Sysdig; wire: THN.
Exploit-DB entry 52676 (dated 2 September 2026) packages a Metasploit module for CVE-2026-29053: crafted Ghost CMS themes can execute arbitrary code on the host. The module lists affected releases from 0.7.2 through 6.19.0 and notes that for versions 5.105.0–5.130.5 and 6.0.0–6.10.3 it can also leverage a related 2FA bypass (CVE-2026-22594). Endor Labs write-up GHSA-cgc2-rcrh-qr5x is cited as the research reference. Upgrade Ghost past the fixed releases; restrict who can upload themes; review installed themes for unexpected Handlebars templates.
