CVE-2026-121430 Details
Description
AzuraCast before 0.24.0 contains a missing authorization vulnerability in the GET and POST /api/station/{station_id}/waveform/{media_id} routes, which lack Permissions middleware. Any authenticated user without station assignment can read another station's cached waveform JSON and overwrite it with attacker-supplied data, corrupting Visual Cue Editor data.
A missing authorization vulnerability has been identified in AzuraCast versions prior to 0.24.0. The issue resides in the GET and POST /api/station/{station_id}/waveform/{media_id} routes, which do not include the necessary Permissions middleware. This oversight allows any authenticated user, regardless of station assignment, to access another station's cached waveform JSON and replace it with attacker-controlled data, thereby corrupting the Visual Cue Editor data for that station.
To address this vulnerability, AzuraCast should implement the missing Permissions middleware for the affected waveform API routes. Additionally, a regression test should be added to ensure that all station-related media routes properly enforce authorization checks.
