Android 0-day Vulnerability on Google Pixel Devices Actively Exploited in Attacks

Google patched CVE-2026-58704, an actively exploited Android zero-day allowing proximal privilege escalation via the Pixel cellular modem, urging the 2026-09-05 patch.

Google confirmed CVE-2026-58704, a high-severity elevation-of-privilege flaw in the Pixel cellular modem, is being exploited in limited, targeted attacks and shipped emergency fixes in the September 2026 Pixel Update Bulletin. The low-complexity bug requires no user interaction and enables proximal/adjacent privilege escalation with no additional execution privileges, phrasing Google has historically used for spyware-vendor and state-aligned zero-days. The Pixel bulletin patches 110 flaws including 12 critical RCEs, while the broader September Android update addressed roughly 180 vulnerabilities, including Wi-Fi memory-corruption bug CVE-2026-28662.

China-Linked Hackers Chain Chrome Zero-Day With Windows Kernel Flaw in Attacks

Volexity reports China-linked UTA0560 and JungleBamboo chained Chrome zero-day CVE-2026-85046 with kernel flaws to spy on NGOs.

Volexity documented campaigns detected on September 1, 2026, in which China-linked actors UTA0560 and JungleBamboo (APT31) chained CVE-2026-85046 (V8 type confusion), CVE-2026-87491 (WebAssembly sandbox escape), and CVE-2026-85880 (Windows kernel privilege escalation in RtlpCreateServerAcl). Victims were lured via links on legitimate U.S. university sites vulnerable to reflected XSS, then served hidden exploit iframes behind a donation-form image. Although a V8 fix had landed in Chromium's source after private August reporting, Chrome had not yet shipped it, creating a patch gap the actors exploited. The two groups installed distinct payloads: UTA0560 delivered the GRIMWEDGE JScript backdoor via DLL side-loading, while JungleBamboo used the SUPERSTOMP loader to install the LONGTALE credential-stealing Chrome extension disguised as Google Gemini.

Attackers Exploit Issabel Framework Flaw Enabling Unauthenticated OS Command Execution

Attackers actively exploit CVE-2026-89026, a hard-coded JWT key flaw enabling unauthenticated OS command execution on Issabel PBX systems.

VulnCheck reported active exploitation of CVE-2026-89026 (CVSS v3.1 9.8) in Issabel Framework, the web framework for the open-source Issabel unified communications PBX. A hard-coded HS256 JWT signing key identical across every installation lets unauthenticated attackers forge bearer tokens and abuse the /pbxapi/manager/originate endpoint, causing Asterisk to execute arbitrary OS commands as the Asterisk user. A patch replacing the hard-coded key with one stored in /etc/issabel.conf shipped August 1, 2026, and the Shadowserver Foundation first observed exploitation on September 9, 2026. Details on real-world abuse, attribution, and scale remain unknown.

Acronis cPanel Backup Plugin Vulnerability Exploited in Targeted Attacks

Acronis warns CVE-2026-87886, a local privilege escalation flaw in its cPanel/WHM and Plesk backup plugins, is exploited in targeted attacks.

Acronis disclosed CVE-2026-87886 (CVSS 7.8), a high-severity local privilege escalation caused by insecure file permissions in its Backup plugin for cPanel & WHM and Backup extension for Plesk on Linux. Affected versions include cPanel & WHM plugin builds before 1.9.3.1021 (fixed in 1.9.3 HF3) and Plesk extension builds before 1.8.11.638. A low-privileged attacker could escalate permissions and potentially run arbitrary code, impacting confidentiality and integrity of the application. Acronis says exploitation has been detected in the wild in limited, targeted attacks, but has not identified the attackers, timing, or objectives.

Chinese Hackers Exploit Critical Tencent Software Flaw for One-Click Code Execution

China-linked UNC3569 actively exploited critical Sogou Input Method flaw CVE-2026-51990 for one-click system-level code execution, deploying the GrayRabbit backdoor.

Gen Threat Labs reports that China-linked threat actor UNC3569, possibly tied to contractor i-SOON, exploited critical CVE-2026-51990 in Tencent's Sogou Input Method, a Windows IME used by hundreds of millions, via crafted sgbiz URLs. The chain combines unvalidated command-line argument injection, unrestricted URL navigation, and an un-sandboxed Chromium 80 engine missing roughly six years of security patches. The exploit gives system-level code execution and was used to deploy the GrayRabbit backdoor, which provides a reverse shell, plugin loading, file upload to C2, and system info collection, and has appeared in UNC3569 intrusions since at least 2021. Tencent patched the issue in version 16.3.0.3498 via automatic update, but the outdated Chromium configuration reportedly remained unchanged as of September 10.
