CVE-2026-104468 · Severity: medium · CVSS 4.8 · Published 2026-10-02

YesWiki is a wiki platform that allows users to reset their passwords when needed. This vulnerability allows attackers to take over accounts by reusing old password reset links that never expire. An attacker who finds an old reset link in email backups, browser history, or server logs can use it to change the password and gain full account access indefinitely after it was originally issued.

## Technical details

YesWiki's password recovery mechanism in sendPasswordRecoveryEmail() generates reset tokens and stores them without expiration timestamps. The checkEmailKey() validation function only checks token existence, not validity or age, allowing indefinite reuse until the token is replaced by a new reset request. An unauthenticated attacker with access to old reset URLs can submit new passwords and take over any account.
