Google Chrome: Information leak in Passwords component
Summary
Google Chrome desktop versions before 155.0.8059.39 contain an information leak in the built-in Passwords component (CWE-200). A remote attacker can obtain sensitive information by luring a user to a crafted HTML page, so the victim only needs to open the page in an affected browser. The NVD rates it CVSS 8.8, but Chromium rates it Low and the impact described is information disclosure, so the score should be treated with caution. Password exposure is the main business risk.
Affected
- Google Chrome desktop prior to 155.0.8059.39
- Linux chromium packages prior to 155.0.8059.39 (e.g. Debian bookworm, SUSE)
- Other Chromium-based browsers: unverified, a third-party entry lists Microsoft Edge below 155.0.4283.45
Fixed in
- Google Chrome 155.0.8059.39 (Linux) and 155.0.8059.39/.40 (Windows, macOS), per the Chrome Releases post
- Debian bookworm chromium: 155.0.8059.39-1~deb12u1
- Later stable builds include further Passwords fixes; install the latest stable release
- Microsoft Edge: fixed build unverified, check MSRC
Workaround
Unknown. No workaround found; updating is the only documented remedy.
Exploitation
- CISA: not marked as known exploited, not listed in CISA KEV
- EPSS about 0.003 (as reported by Vulners)
- No public proof of concept found
- No in-the-wild exploitation known
Our recommendation
- Inventory Chrome, Edge, other Chromium-based browsers and Linux chromium packages, and flag any version below 155.0.8059.39
- Deploy the latest stable Chrome build, not only 155.0.8059.39, because later Passwords fixes exist
- Verify the fixed Edge build with Microsoft MSRC
- Ensure users cannot postpone browser updates; monitor the Chromium bug and Chrome Releases for technical details
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
