This results in the disclosure of the entire permission matrix that maps user groups to plugin capabilities.

The vulnerability is not listed in the CISA KEV catalog, and no public exploit is known.

Once accessed, the endpoint returns full permission mappings in JSON format, allowing straightforward data extraction. Consequently, the risk is moderate for exposed data and low for immediate exploitation, but the lack of authentication makes it trivial for a determined adversary."}}}}, "created": "2026-03-24T10:33:34.952680+00:00", "updated": "2026-03-25T20:37:25.896991+00:00", "vendors": ["wwbn", "wwbn$PRODUCT$avideo"]}
