CVE-2026-13780 is a critical flaw (CVSS 9.6) in ANGLE in Google Chrome before 150.0.7871.47. Insufficient validation of untrusted input could let an attacker who already compromised the renderer escape the sandbox via a crafted page. Update Chrome to 150.0.7871.47 or later.
What's affected
The record says Google Chrome prior to 150.0.7871.47 is affected, on Windows, macOS and Linux. The fixed version is 150.0.7871.47 or later. The record points to the June 2026 Chrome stable channel update post for the desktop release notes. That page loads its content with scripts and did not render for our fetch, so open it in a browser to see the exact build numbers per platform.
Other Chromium based browsers take Chromium fixes on their own schedule, so check each vendor.
How to check if you're exposed
Open chrome://version in the address bar and read the version number. Anything below 150.0.7871.47 is in range. To trigger an update, open the three dot menu, choose Help, then About Google Chrome, and relaunch when asked.
For managed fleets, check the version through your device management console or with a script that reads the installed Chrome version on each platform.
What to do now
- Open chrome://version and check the build is 150.0.7871.47 or later.
- Use About Google Chrome to update and relaunch the browser.
- Confirm your fleet policy lets Chrome update, and relaunch long running sessions.
- Check other Chromium based browsers and embedded runtimes such as Electron apps against their vendor advisories.
- Keep an eye on the Chrome releases blog for new stable updates.
Why it matters
The weakness class is improper input validation. ANGLE translates graphics calls from web content, so it receives data from pages that cannot be trusted and has to check it before acting. When a check is missing, a bad value can reach code that assumes it is sound.
The vector includes user interaction and a changed scope, which matches a sandbox escape. The record says the attacker had compromised the renderer first. It does not flag the CVE as known exploited.
The record lists this weakness class: CWE-20 (Improper Input Validation).
Quick check
Why does the vector say user interaction is required?
The attack runs through a crafted web page, so someone has to load it. The sandbox escape step comes after the renderer is compromised.
