CVE-2026-93340

Description

Gladys Assistant before 5.1.0 contains a password reset link poisoning vulnerability that allows unauthenticated remote attackers to obtain valid password reset tokens for any account by exploiting the client-supplied origin parameter in the forgot_password endpoint without server-side validation. Attackers can send a crafted request specifying an attacker-controlled origin, causing the victim to receive a poisoned reset link that discloses the session token to the attacker, enabling full account takeover including administrator accounts.
