Sandbox escape race condition in Google Chrome DevTools

IdentifiersCVE-2026-13025CWE-20

CVE-2026-13025 is a high-severity vulnerability in DevTools in Google Chrome prior to 149.0.7827.197. The issue is described by Google and downstream advisories as insufficient validation of untrusted input in DevTools, with the primary description characterizing it as a race condition. A remote attacker who has already compromised the renderer process can trigger the flaw via a crafted HTML page and potentially escape Chrome’s sandbox. Specific vulnerable functions or code paths were not provided in the available content, and Google restricted detailed technical information at disclosure time.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can allow an attacker who already has renderer-process compromise to bypass Chrome’s sandbox boundary. This can enable execution outside the renderer sandbox and materially increase the attacker’s control over the browser or host environment, representing a security restriction bypass and potential step toward broader system compromise.

Mitigation

If you can’t patch tonight, do this now.

No specific workaround was provided in the available advisories. Mitigate exposure by applying vendor updates promptly, reducing use of untrusted web content until patched, and prioritizing patching on systems where renderer compromise would present elevated risk. Standard browser hardening and least-privilege controls may reduce post-exploitation impact but do not remediate the flaw.

Remediation

Patch, then assume compromise.

Upgrade Google Chrome to version 149.0.7827.197 or later. For Debian chromium, upgrade to 149.0.7827.196-1~deb13u1 or later patched package versions. Chromium-based downstream products should be updated once vendor patches are available.
