Summary

Moderator Toolbox (reddit-moderator-toolbox) before 4.0.14 contains a stored cross-site scripting vulnerability in the removalreasons module, which inserts subreddit toolbox wiki fields into popup HTML without encoding. Attackers who can edit the toolbox wiki page can plant JavaScript in fields like pmsubject, header, or reason titles to act with moderators' Reddit sessions.

Risk Assessment

An attacker can execute arbitrary JavaScript in the context of a moderator's session, hijacking their privileges. This may lead to content modification, data theft, or further privilege escalation.

Recommendation

Update Moderator Toolbox to version 4.0.14 or later. Review and sanitize toolbox wiki pages for malicious scripts.
