CVE-2026-44648

Description

SillyTavern: Existing sessions are not invalidated after password change, allowing session reuse and account takeover

Description (MITRE) cveawg.mitre.org

Pulled from cveawg.mitre.org/api/cve/CVE-2026-44648 on 2026-07-01. Shown when MITRE's text differs from the cvelistV5 mirror.

SillyTavern is a locally installed user interface that allows users to interact with text generation large language models, image generation engines, and text-to-speech voice models. Prior to 1.18.0, SillyTavern relies on cookie-session for authentication, storing all session data (user handle, permissions) in a signed cookie. The endpoints POST /api/users/change-password and POST /api/users/recover-step2 only update the password hash in the database but do not expire current sessions. Because the session is stateless and stored entirely in the client cookie, there is no server-side mechanism to revoke a token once issued. This vulnerability is fixed in 1.18.0.
