CVE-2026-4982 | BDVDB-2026-323341 Detail

pretixVenueless

Description#

A user with permission "update world" in any Venueless world is able to exfiltrate chat messages from direct messages or channels in other worlds on the same server due to a bug in the reporting feature. The exploitability is limited by the fact that the attacker needs to know the internal channel UUID of the chat channel, which is unlikely to be obtained by an outside attacker, especially for direct messages.
