WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 fails to validate playlist ownership in the Playlists_schedules/list.json.php and Live/calendar.json.php endpoints, allowing authenticated and unauthenticated users to read private playlist schedule metadata. Attackers with canStream privileges or no authentication can retrieve schedule names, descriptions, timestamps, and playlist identifiers by querying these endpoints without ownership checks.
AnalysisAI
Private playlist schedule metadata in WWBN AVideo (through commit c3edcc274c389816d434acadac07ee78eaf330c1) is exposed via missing ownership validation in the Playlists_schedules/list.json.php and Live/calendar.json.php PHP endpoints. Both unauthenticated requesters and low-privilege users holding canStream rights can supply arbitrary playlist identifiers to retrieve private schedule names, descriptions, timestamps, and playlist identifiers with no ownership verification performed server-side. …

Vulnerability AssessmentAI
| Exploitation | The two vulnerable endpoints - Playlists_schedules/list.json.php and Live/calendar.json.php - must be network-reachable, which applies to any internet-facing or intranet-accessible AVideo installation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.3 with VC:L accurately reflects the limited blast radius - only read-only schedule metadata is exposed, with no write capability, credential leakage, or content-file access involved. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Operators should apply any upstream commit that introduces ownership validation logic in Playlists_schedules/list.json.php and Live/calendar.json.php, consulting the GitHub security advisory GHSA-f4q2-49rm-rxh7 at https://github.com/WWBN/AVideo/security/advisories/GHSA-f4q2-49rm-rxh7 for the authoritative fix reference. … Detailed patch versions, workarounds, and compensating controls in full report. |
