Actively exploited. CVE-2026-85046 is listed in the CISA Known Exploited Vulnerabilities catalog (added 2026-09-04) — exploitation has been observed in the wild, and US federal agencies are required to remediate it under BOD 22-01. Treat patching as urgent.
Public exploit code is available. Proof-of-concept or working exploit code for CVE-2026-85046 is indexed in GitHub PoC. Expect opportunistic scanning and exploitation attempts — prioritize remediation.
CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation. CVE-2026-85046 Google Chromium V8 Type Confusion Vulnerability This type of vulnerability is a frequent attack vector for malicious cyber actors and poses significant risks to the federal enterprise. Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA’s KEV Catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities. BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied. While BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV Catalog vulnerabilities . CISA will continue to add vulnerabilities to the catalog that meet the specified criteria . Aware of an exploited vulnerability not currently listed in the KEV Catalog? Submit it for potential addition through CISA’s KEV Nomination Form . Potential KEV additions must have a CVE ID, evidence of exploitation, and clear mitigation guidance.
CSIRTS triage
- What
- Multiple vulnerabilities in Chrome allow remote code execution, information disclosure, and security mechanism bypass.
- Who is affected
- All Chrome browser users, particularly those visiting untrusted websites or receiving socially engineered content.
- Urgency
- Critical priority because remote code execution in a web browser is widely exploitable and frequently targeted; high-severity browser compromise affects all web-accessible user data and system access.
- Action
- Update Chrome to the latest version immediately; enable automatic updates if not already enabled.
