Google Chrome: Uncontrolled search path element in CredentialProvider on Windows
Summary
Google Chrome on Windows before 155.0.8059.39 contains an uncontrolled search path element (CWE-427) in the CredentialProvider component. A local attacker who can get a program onto the system may be able to execute arbitrary code outside the browser sandbox. Exploitation requires user interaction, and the attack is only possible locally.
Affected
- Google Chrome on Windows prior to 155.0.8059.39
- Google Chrome on Mac prior to 155.0.8059.40 (per vendor advisory; not named in CVE text)
Fixed in
- Google Chrome 155.0.8059.39 (Windows and Linux)
- Google Chrome 155.0.8059.40 (Mac)
Workaround
Unknown. A patched build is available, so applying the update is the fix.
Exploitation
- No evidence of exploitation in the wild found.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
- Not in the CISA KEV catalog.
- No public proof-of-concept code found.
Our recommendation
- Confirm all Windows endpoints run Chrome 155.0.8059.39 or later (155.0.8059.40 on Mac).
- Check managed deployments and long-running sessions, since browsers that never restart keep the old build loaded.
- Limit standard users' write access to directories on the system search path.
- Keep Chrome automatic updates enabled.
