OX Research (8 September 2026) and VulnCheck advisory: CVE-2026-82533 (CWE-807) in DeepSeek Harness (dsh) before 0.1.2-alpha.1. The local agent-control HTTP API trusted only the client-supplied Host header, not the TCP peer. The OS sandbox confined file writes but left loopback networking open, so a sandboxed agent could curl the API, set danger-full-access / approval never, and run unconfined — on shipped defaults, with no credentials. If the port was reachable via tunnel/proxy/SSH forward, an unauthenticated remote attacker could control the agent and export stored conversations. CVSS 4.0 9.4 (AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H). Disclosed to VulnCheck CNA 24 Aug; fixed in 0.1.2-alpha.1 (27 Aug); CVE published 8 Sep. npm package @deepseek-ai/dsh — install 0.1.2-alpha.2+ / current rc. Primary: OX Research; also VulnCheck / THN.

THN (9 Sep) confirms no public exploit and absence from CISA KEV catalog version released 8 Sep; notes related July DB and August parking flaws have purported exploit repos online.
The Hacker News (8 September 2026) reports security firm Calif built a worm that takes over a WeChat account via an incoming call and demonstrated spread across three test phones. The callee does not need to answer or touch the phone, but the caller must already be a WeChat contact. Calif reported the flaw to Tencent in July and says the company has since shipped a fix (wire does not name a CVE in the RSS abstract). Treat as a messenger client/patch urgency item for WeChat on iPhone and Android; confirm your app store build is current. Wire-only until a Tencent/CVE primary is linked.

SAP’s September 2026 security patch day (covered 8 September 2026 by BleepingComputer and SecurityWeek) includes CVE-2026-44756, a maximum-severity memory-corruption bug in Extended Passport (EPP) processing in the SAP kernel, dubbed OVERPASS by Onapsis. Missing boundary checks on externally supplied length fields during EPP deserialization can let unauthenticated attackers run OS commands as the SAP installation owner, recover DB credentials/password hashes, read live user sessions, and modify data/binaries. Onapsis says EPP is hit as a session opens (before authz controls), via web/ICM, SAP GUI, and RFC; products relying on the vulnerable kernel include S/4HANA, ERP/ECC, NetWeaver, Web Dispatcher, BW/4HANA, Enterprise Portal, PI/PO, Solution Manager and others. Onapsis estimates >10,000 internet-facing SAP web interfaces; no in-the-wild exploitation indicators reported for OVERPASS at publish. Same cycle: CVE-2026-58240 (S4GET) missing authentication on NetWeaver Message Server enabling unauth cluster RCE as <sid>adm; also critical CVE-2026-76969 (CAP credential disclosure) and CVE-2026-66768 (NetWeaver access control). Apply SAP Security Notes for September 2026 immediately; do not invent CVSS for sister CVEs beyond vendor/Onapsis statements. Primary research: Onapsis; wires: BleepingComputer / SecurityWeek.
BleepingComputer — SAP OVERPASS CVE-2026-44756 (8 Sep 2026)
Microsoft’s 8 September 2026 Patch Tuesday is its largest security release on record. BleepingComputer counts 966 flaws shipped on Patch Tuesday itself (105 Critical, including 81 RCE), excluding 204 flaws fixed earlier in the month in cloud products; SecurityWeek and Krebs count about 974 CVEs across the broader September bundle. Two actively exploited elevation-of-privilege zero-days are fixed: CVE-2026-81963 (Windows Update Stack link-following to SYSTEM; credited to Romain Deperne and MSTIC) and CVE-2026-85880 (Windows ALPC heap buffer overflow to SYSTEM / AppContainer sandbox escape; Volexity and Proofpoint researchers). Coverage notes ~20 potentially wormable unauthenticated RCEs in the set and calls out Exchange (CVE-2026-55007), SharePoint (CVE-2026-69465), RDS (CVE-2026-69525), SQL (CVE-2026-65669), and Authenticator (CVE-2026-80097) among high-priority items. Microsoft attributes the volume increase partly to AI-assisted vulnerability discovery. NEW 8 Sep KEV: CISA added both exploited zero-days to the Known Exploited Vulnerabilities catalog on 2026-09-08 (catalog 2026.09.08) — CVE-2026-81963 and CVE-2026-85880 (FCEB dueDate 2026-09-22). WA SOC advisory 20260909001 (9 September 2026, TLP:CLEAR) summarises the September Monthly Updates as addressing 973 vulnerabilities, highlights critical CVE-2026-69730 and CVE-2026-69525 (CVSS 9.8) plus the two known-exploited EoPs (CVSS 7.8), notes Microsoft detected exploitation of one or more of the mentioned vulnerabilities, and says WASOC has not received WA Government exploitation reports at the time of writing. Prioritise the two exploited EoPs, internet-facing roles, and Extended Security Updates where applicable.

The Hacker News (8 September 2026) summarises Red Hat guidance that a FreeIPA flaw lets a client that has never logged in create a Kerberos identity of its choosing in the directory and end up in the administrators group. FreeIPA stores identities in 389 Directory Server over LDAP; the attack also needs a second flaw in that database software. Wire abstract does not list CVE IDs or fixed package versions — operators should pull current RHEL/FreeIPA errata from Red Hat rather than inventing patch levels. Primary wire: The Hacker News pending RHSA deep-link. Watchlist relevance: Red Hat / identity plane.
Progress Telerik critical security bulletin (updated 22 July 2026) covers a chain in UI for ASP.NET AJAX RadAsyncUpload / RadPersistenceManager / RadDockLayout (CVE-2026-13181 through CVE-2026-13186 and CVE-2026-13190).

Adobe published emergency hotfix APSB26-146 on 7 Sep 2026 ~20:20 UTC (priority 1) as composer patch VULN-39341 from repo.magento.com; Adobe tested against 2026-aug releases of Adobe Commerce 2.4.4–2.4.9, Magento Open Source 2.4.4–2.4.9, and Adobe Commerce B2B 1.3.3–1.5.3. Exploitation continued after July/August 2026 patch levels; Sansec still advises scan/IoC hunt (kworker/fc-cache/chronyd-style implants, rotate encryption key + credentials). Primary Sansec; vendor APSB26-146. NEW 8 Sep wire: BleepingComputer confirms Adobe’s emergency VULN-39341/APSB26-146 hotfix for CVE-2026-75650 and Sansec’s note that a second, unrelated attacker is also exploiting StyleSmuggler to drop a 485-byte PHP web shell exfiltrating via oast.site/Interactsh-style callbacks — rotate secrets and hunt both Linux-backdoor and PHP-webshell IoCs after patching. NEW 8 Sep KEV: CISA added CVE-2026-75650 to the Known Exploited Vulnerabilities catalog on 2026-09-08 (catalog 2026.09.08); product Adobe Commerce and Magento; FCEB dueDate 2026-09-11; forensicTriage Yes.

MikroTik published an important RouterOS security update on 3–4 September 2026 (supportsec bulletin and forum notice) with details withheld, fixing builds 7.25 beta 3, 7.24.2, 7.23.4 and 6.49.21. On 5 September 2026 CERT Polska disclosed six coordinated CVEs and confirmed active exploitation. Highest-impact pair (CERT.PL CVSS 9.2 each): CVE-2026-67276 SSH authentication bypass (RouterOS did not fully compare RSA public keys, so an attacker who knew a username and the public modulus could craft another key and log in without the private key) and CVE-2026-86060 SSH session privilege manipulation via a crafted username that yields a full-admin session. CVE-2026-67277 (CVSS 8.8) is unauthenticated bandwidth-test memory disclosure/crash. CVE-2026-67281 (CVSS 4.0 8.7 per CVE record) is unauthenticated WebFig /jsproxy file read that can disclose root-owned config stores. CERT.PL also lists CVE-2026-67278 and CVE-2026-67279 on the CVE details page. CERT.PL says the MikroTrick combination of two SSH flaws is being used for full takeover of devices with SSH on public networks; successful attacks creating a privileged user named ops have been seen from 82.192.72.4 since at least 2 September 2026, with 103.102.31.18 used in exploit attempts. Log IoCs include login failure for user -2 via ssh and user <name> added by ssh:-2@<ip>. Fixed releases set a Flagged marker when known compromise traces are found (absence of Flagged is not clean). The Hacker News (6 September 2026) notes CERT.PL guidance to prefer 7.23.5 on the long-term 7.23 channel (after 7.23.4). Latvia's national CERT also reported increased MikroTik targeting and urged the same patched builds. Until patched: restrict SSH, WWW/WWW-SSL and bandwidth-test to trusted management nets; do not initiate TLS or built-in SSH clients from an unpatched box toward untrusted hosts. If Flagged or otherwise suspect: isolate, preserve logs/config, factory-reset and rebuild from a verified config, rotate secrets. Primary: CERT Polska active-exploitation advisory. UPDATE 10 September 2026: CISA added CVE-2026-86060 and CVE-2026-67277 to KEV (dateAdded 2026-09-10). Internet-exposed SSH / bandwidth-test paths remain the priority; patch and hunt Flagged / ops / ssh:-2 IoCs.
