CVE-2026-62685
Last modified
CVE-2026-62685 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.63.17, File Browser builds new user scopes from usernames passed through cleanUsername() when Signup=true and CreateUserDir=true, but the many-to-one normalization can collapse usernames such as team/one, team one, and team-one to the same home directory without checking whether the resulting scope is already taken, allowing a second registrant to gain full read and write access to another user's files. EPSS estimates a 0.32% chance of exploitation in the next 30 days.
