The EPSS score is not available, and the flaw is not listed in the CISA KEV catalog. The attack requires the attacker to be authenticated and to have streaming permissions, after which they can directly fetch the target data through the vulnerable endpoint. The most likely attack vector is an internal user or compromised account leveraging normal streaming privileges to request or export the configuration of other users. Given the sensitivity of stream keys and OAuth tokens, any successful exploitation can lead to significant account compromise and service disruptions."}}}}, "created": "2026-04-22T04:15:07.395625+00:00", "updated": "2026-04-22T05:30:09.557867+00:00", "vendors": ["wwbn", "wwbn$PRODUCT$avideo"]}
