Password recovery exploitation via unsigned authorization tokens
Published May 27, 2026 · Updated May 27, 2026
Authentication bypass in Revmakx WP Time Capsule 1.22.25 and earlier allows remote attackers to exploit password recovery requests. The INITIAL_SETUP callback accepts the authorization-field token without verifying its signature, so attacker-supplied callback data is treated as authenticated. No account or user interaction is required; the published impact is limited to exposure of confidential password-recovery information.

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.
