Enterprises Warned of Attacks Exploiting WSO2 Vulnerability

Attackers are actively exploiting CVE-2026-5430 (CVSS 10), a WSO2 JWT authentication bypass, to access enterprise API credentials and sensitive data.

WatchTowr's honeypot network recorded the first exploitation attempt of CVE-2026-5430 on September 13, roughly two months after the CVE record was published in early August. The flaw, patched by WSO2 in April with an advisory in May, carries a maximum CVSS score of 10 and allows JWT authentication bypass via tokens signed with unsupported algorithms, enabling unauthorized access and full account takeover. A forged JWT observed in the wild granted access to API backend endpoints, credentials, and consumer keys and secrets for every registered application. WSO2's API Manager, API Control Plane, Traffic Manager, and Universal Gateway are affected, and the platform serves nearly 1,000 enterprise customers in banking, government, telecom, and logistics.

Google Patches Pixel Modem Flaw Amid Signs of Limited Targeted Exploitation

Google's September Pixel update patches CVE-2026-58704, a high-severity cellular modem privilege escalation flaw showing signs of limited targeted exploitation.

Google disclosed CVE-2026-58704 (CVSS 8.0), a privilege escalation flaw in the Pixel Cellular Modem caused by a logic error permitting proximal/adjacent privilege escalation with no user interaction or extra privileges needed. Google acknowledged indications the flaw may be under limited, targeted exploitation but did not identify the threat actor. The September 2026 Pixel update fixes 109 additional flaws, including 46 critical-severity issues in components such as BigOcean, Bootloader, IMS, and Trusted Execution Environment, plus two high-severity kernel privilege escalation bugs (CVE-2026-56914, CVE-2026-58773). Security patch level 2026-09-05 or later resolves all identified flaws.

CISA Adds Two Known Exploited Vulnerabilities to Catalog

CISA added actively exploited CVE-2026-76460 (Cisco Identity Services Engine) and CVE-2026-87886 (Acronis Backup) to its KEV catalog.

CISA added two vulnerabilities to its Known Exploited Vulnerabilities Catalog based on evidence of active exploitation: CVE-2026-76460, an incorrect use of privileged APIs flaw in Cisco Identity Services Engine, and CVE-2026-87886, an incorrect default permissions flaw in Acronis Backup. Under Binding Operational Directive 26-04, Federal Civilian Executive Branch agencies must prioritize rapid remediation of KEV vulnerabilities on publicly exposed assets that grant total control post-exploitation, and check whether systems were compromised before patching.

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.
