CVE-2026-113215 Google CVE debrief

Who should care

Defenders responsible for managing Google Chrome deployments, particularly in environments where remote access or untrusted input is common, should assess exposure and prioritize patching.

Why it matters

A use-after-free vulnerability in Google Chrome's Extensions requires verification of affected versions and potential exploitation to prevent remote code execution within the sandbox.

• Potential remote code execution within the sandbox requires verification and patching to prevent exploitation.
• Defenders must verify Chrome versions and apply patches to prevent potential code execution.
• Incident response plans should be reviewed and updated to address potential exploitation attempts.

Technical summary

The CVE record describes a use-after-free vulnerability in Google Chrome's Extensions prior to version 156.0.8078.47. This allows remote attackers to execute arbitrary code within the sandbox via a crafted HTML page. The Chromium security severity is reported as Low. The vulnerability affects Google Chrome's Extensions, which is a critical component for managing browser functionality. Defenders should prioritize verifying Chrome versions and applying patches to prevent potential code execution within the sandbox. The vulnerability requires verification of affected versions and potential exploitation to prevent remote code execution within the sandbox.

Defensive priority

Defenders should prioritize verifying Chrome versions and applying patches to prevent potential code execution within the sandbox.

Recommended defensive actions

• Verify Chrome version and apply patches
• Monitor for potential exploitation attempts
• Review and update incident response plans
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
• Review compensating controls for exposed systems while remediation is scheduled and verified.

Evidence notes

The CVE record and source item provide details on the vulnerability, but additional verification is needed to confirm affected versions and potential exploitation. The vulnerability is reported to have a Low severity by Chromium, and defenders should verify Chrome versions and apply patches to prevent potential code execution within the sandbox. Evidence from the CVE record and source item should be reviewed, and defenders should be aware of the potential for exploitation in environments where remote access or untrusted input iscommon
