{"apiVersion":"1.0","identifier":"CVE-2026-41056","description":"WWBN AVideo is an open source video platform. In versions 29.0 and below, the `allowOrigin($allowAll=true)` function in `objects/functions.php` reflects any arbitrary `Origin` header back in `Access-Control-Allow-Origin` along with `Access-Control-Allow-Credentials: true`. This function is called by both `plugin/API/get.json.php` and `plugin/API/set.json.php` — the primary API endpoints that handle user data retrieval, authentication, livestream credentials, and state-changing operations. Combined with the application-s `SameSite=None` session cookie policy, any website can make credentialed cross-origin requests and read authenticated API responses, enabling theft of user PII, livestream keys, and performing state changes on behalf of the victim. Commit caf705f38eae0ccfac4c3af1587781355d24495e contains a fix.","publishedAt":"2026-04-21T23:16:20","lastModifiedAt":null,"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-41056","cvssScore":8.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","epssProbability":0.00335,"riskScore":0.83,"affectedProduct":"WWBN AVideo","affectedVersions":"<29.0","vulnerabilityType":"Core software","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-41056","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-41056","en":"https://www.redsauce.net/en/cves/CVE-2026-41056","fr":"https://www.redsauce.net/fr/cves/CVE-2026-41056","pt":"https://www.redsauce.net/pt/cves/CVE-2026-41056","de":"https://www.redsauce.net/de/cves/CVE-2026-41056","sk":"https://www.redsauce.net/sk/cves/CVE-2026-41056","el":"https://www.redsauce.net/el/cves/CVE-2026-41056"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-41056"}}
