DescriptionCVE.org

Inappropriate implementation in Safe Browsing in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to bypass discretionary access control via a crafted RAR file. (Chromium security severity: Medium)

AnalysisAI

Safe Browsing bypass in Google Chrome prior to 149.0.7827.53 allows a remote attacker to circumvent discretionary access control protections by delivering a specially crafted RAR file to a victim who interacts with it. The CVSS vector (AV:N/AC:L/PR:N/UI:R) confirms no authentication or elevated privileges are required on the attacker side, but exploitation depends on user interaction - the victim must engage with the malicious RAR file. The integrity impact is rated High (I:H) with no confidentiality or availability impact, indicating the primary risk is bypassing file-based access controls enforced by the Safe Browsing subsystem. No public exploit identified at time of analysis, and EPSS at 0.02% (4th percentile) reflects very low observed exploitation probability.

Technical ContextAI

The vulnerability resides in Chrome's Safe Browsing subsystem, a security layer designed to warn users about or block potentially dangerous files, URLs, and downloads. CWE-284 (Improper Access Control) identifies the root cause as a failure to correctly enforce access control decisions - specifically, an 'inappropriate implementation' in how Safe Browsing processes or evaluates RAR archive files. RAR archives are container formats that can embed arbitrary content; a crafted RAR may exploit parsing edge cases, malformed headers, or nested structures to confuse the Safe Browsing engine into issuing an incorrect allow decision where it should block. Affected versions are confirmed as all Chrome releases prior to 149.0.7827.53 per the ENISA EUVD entry (EUVD-2026-34671) and the Google stable channel advisory.

RemediationAI

Update Google Chrome to version 149.0.7827.53 or later; this is the vendor-released patch confirmed by the stable channel advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html. Chrome typically auto-updates, but administrators managing enterprise fleets should verify deployment via policy and confirm the version through chrome://settings/help. As a compensating control prior to patching, organizations may consider blocking RAR file downloads at the email gateway or web proxy layer - note this may disrupt legitimate use of compressed archives. Enabling Enhanced Safe Browsing mode in Chrome (Settings > Privacy and security > Security > Enhanced protection) may provide additional heuristic coverage, though it is not confirmed to mitigate this specific bypass. Do not rely on Safe Browsing alone as a file-vetting control until patched; pair with endpoint detection tools that inspect archive contents independently of Chrome.
