An attacker can craft an HTML page that causes Chrome to ignore standard download restrictions, allowing a file to be downloaded silently or with reduced warnings. If the user opens the page, the browser may download a malicious file and enable its execution, compromising the integrity of the system and potentially exposing sensitive data. The weakness corresponds to CWE\u20111289 and CWE\u201120.", "risk_and_exploitability": "The CVSS score of 4.3 indicates medium severity, while the EPSS score of less than 1\u202f% denotes a low likelihood of exploitation in the near term.

An attacker would need to lure a user to a malicious HTML page to activate the download bypass, so the threat is moderate but warrants attention, especially for users handling downloads from untrusted sources."}}}}, "created": "2026-04-09T08:17:05.444226+00:00", "updated": "2026-04-14T16:37:41.440989+00:00", "vendors": ["google", "google$PRODUCT$chrome"]}
