CVE-2026-87549 Details
Description
Incomplete cleanup in Downloads in Google Chrome prior to 153.0.8010.36 allowed a remote attacker leveraging social engineering to bypass system access restrictions via a crafted HTML page. (Chromium security severity: Medium)
A vulnerability exists in the Downloads component of Google Chrome, in versions prior to 153.0.8010.36, due to incomplete cleanup processes. This flaw enables remote attackers to bypass system access restrictions by exploiting a crafted HTML page, leveraging social engineering tactics. The root cause lies in the handling of parallel downloads, where trailing bytes from a malicious payload can remain on disk and escape the hash validation process used by Safe Browsing, potentially allowing harmful files to be downloaded without detection.
Users should update to Google Chrome version 153.0.8010.36 or later, where this vulnerability has been fixed.
