Permissions where checked incorrectly during room creation, allowing attackers to create rooms of types they shouldn't be allowed to create.
AnalysisAI
Incorrect authorization logic during room creation in Venueless permits authenticated low-privilege users to create room types they are not permitted to create. The CVSS 4.0 score of 2.3 reflects the narrow, integrity-only impact and significant attack preconditions - requiring authentication, high complexity, and specific prerequisites. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session on the Venueless platform with at minimum low-privilege credentials (PR:L confirmed by CVSS 4.0 vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 2.3 accurately reflects the limited real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated Venueless user with a low-privilege account - such as an attendee or limited organizer role - crafts a room creation API request specifying a restricted room type (e.g., a backstage or admin-only room) that their role should not be authorized to create. Due to the incorrect server-side permission check, the request is accepted and the room is created, granting the attacker unintended room management capabilities within the event platform. … |
| Remediation | Apply the patch referenced in GitHub Security Advisory GHSA-hj6j-wpgc-qrp5 (https://github.com/venueless/venueless/security/advisories/GHSA-hj6j-wpgc-qrp5). … Detailed patch versions, workarounds, and compensating controls in full report. |
