This vulnerability (CVE-2026-4982) involves improper input validation (CWE-20) in the pretix Venueless platform. A user with limited privileges (permission to "update world") can exploit a bug in the reporting feature to access chat messages from other worlds on the same server, including direct messages and channels. The attack vector requires the attacker to know the internal UUID of the chat channel, which is unlikely to be exposed to external attackers. The CVSS 4.0 base score is 7.3, indicating a high severity with network attack vector, low attack complexity, and privileges required.

An attacker with the "update world" permission can exfiltrate sensitive chat messages from other worlds on the same Venueless server, potentially exposing private communications. However, the requirement to know internal channel UUIDs significantly limits the exploitability, especially by external attackers. There is no indication of impact beyond information disclosure of chat messages.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor vendor communications for updates. Restricting the "update world" permission to trusted users can reduce risk. No known exploits are reported in the wild at this time.
