Google Chrome: Incorrect authorization in Chromoting on macOS
Summary
Google Chrome on macOS contains an incorrect authorization flaw in Chromoting, the remote-desktop component. A remote attacker can bypass system access restrictions using crafted network traffic. The issue only applies where Chromoting is enabled and accepting incoming remote-desktop connections; Chromium rates it Low, while NVD scores it 9.1 Critical.
Affected
- Google Chrome on macOS prior to 155.0.8059.39 (CNA description)
- Only installations with Chromoting enabled and listening for incoming remote-desktop connections
- Note: sources differ on the range; VulDB lists versions up to 154.0.8037.97 and CWE-284
Fixed in
- Google Chrome 155 Stable for macOS (Chrome Releases, 6 October 2026, build 155.0.8059.39 or .40 for Mac according to sources)
- Debian: 155.0.8059.39-1~deb12u1 (Linux only, not applicable to macOS)
Workaround
Unknown.
- No vendor workaround found. Disabling Chrome Remote Desktop hosting on Macs where it is not needed reduces exposure.
Exploitation
- Not listed in CISA KEV; CISA SSVC: exploitation none, automatable yes, technical impact total.
- EPSS 0.21% according to a third-party tracker, not verified against FIRST.
- No reports of exploitation in the wild and no public proof of concept found.
Our recommendation
- Update Google Chrome on all Macs to the Chrome 155 Stable release or later and verify the installed version.
- Identify Macs with Chrome Remote Desktop hosting enabled and disable it where not needed.
- Ensure inbound remote-desktop connections are not reachable from the internet; prioritise such Macs.
- Monitor for unusual remote-desktop connections on affected hosts.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
