CVE-2026-4982: Pretix Venueless

High severity, CVSS 7.3. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Pretix Venueless: from 0.0.0, before 2026.3.27.e20083a (fixed in 2026.3.27.e20083a)
