{"cve":"CVE-2026-40928","nvd":{"published":"2026-04-21T23:16:20.300","modified":"2026-10-26T21:10:00.170","status":"Analyzed","description":"WWBN AVideo is an open source video platform. In versions 29.0 and prior, multiple AVideo JSON endpoints under `objects/` accept state-changing requests via `$_REQUEST`/`$_GET` and persist changes tied to the caller's session user, without any anti-CSRF token, origin check, or referer check. A malicious page visited by a logged-in victim can silently cast/flip the victim's like/dislike on any comment (`objects/comments_like.json.php`), post a comment authored by the victim on any video, with attacker-chosen text (`objects/commentAddNew.json.php`), and/or delete assets from any category (`objects/categoryDeleteAssets.json.php`) when the victim has category management rights. Each endpoint is reachable from a browser via a simple `<img src=\"…\">` tag or form submission, so exploitation only requires the victim to load an attacker-controlled HTML resource. Commit 7aaad601bd9cd7b993ba0ee1b1bea6c32ee7b77c contains a fix.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L","score":5.4},"cwes":["CWE-352"],"references":["https://github.com/WWBN/AVideo/commit/7aaad601bd9cd7b993ba0ee1b1bea6c32ee7b77c","https://github.com/WWBN/AVideo/security/advisories/GHSA-x2pw-9c38-cp2j","https://github.com/WWBN/AVideo/security/advisories/GHSA-x2pw-9c38-cp2j"],"products":["wwbn:avideo"],"source":"nvd","synced_at":"2026-10-26T21:38:48.864438205+00:00"},"epss":{"cve":"CVE-2026-40928","score":0.00115,"percentile":0.01552,"date":"2026-10-26"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
