The script reads the `key` and `msg` parameters from $_REQUEST, resolves the stream owner via LiveTransmition::keyExists, and verifies that the stream owner (not the caller) is an administrator; it performs no User::isLogged() check and enforces no CSRF token. As a result, an unauthenticated remote attacker who knows an administrator's Live stream key can call sendSocketSuccessMessageToUsers_id and deliver arbitrary in-app/socket notification messages to that administrator. The issue was unpatched at the time of publication."}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Missing Authentication for Critical Function","cweId":"CWE-306","type":"CWE"}]}],"affected":[{"vendor":"WWBN","product":"AVideo","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","versionType":"git","lessThanOrEqual":"c3edcc274c389816d434acadac07ee78eaf330c1"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:wwbn:avideo:-:*:*:*:*:*:*:*"}]}]}],"metrics":[{"format":"CVSS","cvssV4_0":{"version":"4.0","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"NONE","userInteraction":"NONE","vulnConfidentialityImpact":"NONE","vulnIntegrityImpact":"LOW","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","baseScore":6.9,"baseSeverity":"MEDIUM"}},{"format":"CVSS","cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"NONE","baseScore":5.3,"baseSeverity":"MEDIUM"}}],"references":[{"url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-wcg2-x62c-m28x","tags":["vendor-advisory"],"name":"GitHub Security Advisory (GHSA-wcg2-x62c-m28x)"},{"name":"VulnCheck Advisory: WWBN AVideo Missing Authentication via socketMessageLiveOwner.json.php","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/wwbn-avideo-missing-authentication-via-socketmessageliveowner-json-php"}],"credits":[{"lang":"en","value":"santhreal","type":"reporter"}],"x_generator":{"engine":"vulncheck-endgame"}},"adp":[{"references":[{"url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-vr35-39vf-9qp9","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-14T18:26:52.625998Z","id":"CVE-2026-90543","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-14T18:27:32.462Z"}}]}}
