Last modified Jun 17, 2026

CVE-2023-28161 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. If temporary "one-time" permissions, such as the ability to use the Camera, were granted to a document loaded using a file: URL, that permission persisted in that tab for all other documents loaded from a file: URL. This is potentially dangerous if the local files came from different sources, such as in a download directory. EPSS estimates a 0.62% chance of exploitation in the next 30 days.
