The vulnerability arises from inconsistent handling of the videoDirectory GET parameter: one code path truncates the value at the first slash for authorization, while another preserves '..' sequences for file access, creating a split-oracle condition. Consequently, a crafted request can satisfy the authorization check for one video identifier while actually serving the media of another protected video, effectively leaking confidential footage.", "risk_and_exploitability": "The CVSS score of 7.5 signifies a high severity level for confidentiality. The EPSS score is below 1%, indicating that exploitation likelihood is currently low, and the vulnerability is not yet listed in CISA\u2019s KEV catalog. However, the flaw is remotely exploitable from any unauthenticated user capable of issuing HTTP requests to the view/hls.php endpoint with a specially crafted videoDirectory value. The attack vector is likely a direct web request; no special privileges, network access, or additional software is required."}}}}, "created": "2026-03-23T09:45:57.302575+00:00", "updated": "2026-03-25T14:50:33.043568+00:00", "vendors": ["wwbn", "wwbn$PRODUCT$avideo"]}
