CVE-2026-13909
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedInsufficient policy enforcement in DevTools in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Medium)
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceInsufficient policy enforcement in Chrome DevTools prior to version 150.0.7871.47 allowed a remote attacker who had already compromised the renderer process to potentially escape the sandbox via a crafted HTML page. This is a post-compromise privilege escalation vulnerability requiring renderer compromise as a precondition.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Google Chrome versionNavigate to chrome://version in the Chrome browser or run 'google-chrome --version' in terminalAffected if The displayed version is lower than 150.0.7871.47
-
Confirm Chrome release channelNavigate to chrome://settings/help to see if Chrome is stable, beta, or dev channelAffected if Running a non-stable channel below version 150.0.7871.47, as stability channel may differ from fixed version
-
Verify renderer process compromise indicatorReview chrome://inducebrowsercrashforrealz or chrome://crash for unexpected behavior indicating prior compromiseAffected if Any abnormal behavior suggesting the renderer process has been compromised, which is a prerequisite for this exploit
You are affected if your Chrome version is below 150.0.7871.47 and an attacker has already compromised the renderer process, enabling them to potentially escape the sandbox via crafted HTML in DevTools.
