Privilege escalation via misbound authentication timestamps
Published Nov 12, 2025 · Updated Nov 12, 2025
Improper authentication in sudo-rs 0.2.5 through 0.2.9 allows local users to execute permitted commands as other accounts. The timestamp pipeline writes and matches the invoking user's UID rather than the authenticated-as user's UID, so one valid record is reused across target users. Exploitation requires targetpw or rootpw, an unexpired same-terminal timestamp, high sudo privileges, and one permitted target account password.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
