CVE-2026-93453 is a weak password-recovery vulnerability in SOGo versions before 5.12.11. The password-reset workflow constructs recovery URLs using the client-supplied HTTP Origin header as the URL authority. An unauthenticated attacker can submit a password-recovery request with an attacker-controlled Origin value, causing the recovery message sent to the victim to contain a valid reset token in a link directed to attacker-controlled infrastructure.

This two-file repository contains a standalone Python 3.8+ proof-of-concept and supporting README for CVE-2026-93453, an unauthenticated SOGo password-recovery link poisoning issue. `CVE-2026-93453.py` uses only Python standard-library modules (`urllib`, `ssl`, `argparse`, and JSON support), provides configurable target URL, SOGo path prefix, proxy, TLS-verification bypass, and timeout options, and exposes `check` and `poison` commands. The client constructs requests to the target's default `/SOGo/passwordRecoveryEmail` endpoint. `check` uses a random canary username and foreign Origin to distinguish apparent vulnerable 200 responses from the fixed 403 behavior without intentionally mailing a real user. `poison` submits a recovery request for a specified victim with an attacker-controlled Origin, aiming to cause SOGo <=5.12.10 to email a recovery URL containing a valid JWT but pointing to the attacker host. The repository does not implement token-capture infrastructure or automate the final password change; those steps are described in the README. SOGo 5.12.11 is identified as fixed through mandatory `SOGoPasswordRecoveryBaseURLs` Origin allowlisting.
