WWBN AVideo's missing CSRF protection in objects/commentDelete.json.php enables mass comment deletion against moderators and content creators

WWBN AVideo is an open source video platform. In versions 29.0 and prior, `objects/commentDelete.json.php` is a state-mutating JSON endpoint that deletes comments but performs no CSRF validation. It does not call `forbidIfIsUntrustedRequest()`, does not verify a CSRF/global token, and does not check `Origin`/`Referer`. Because AVideo intentionally sets `session.cookie_samesite=None` (to support cross-origin embed players), a cross-site request from any attacker-controlled page automatically carries the victim's `PHPSESSID`. Any authenticated victim who has authority to delete one or more comments (site moderators, video owners, and comment authors) can be tricked into deleting comments en masse simply by visiting an attacker page. Commit 184f36b1896f3364f864f17c1acca3dd8df3af27 contains a fix.

跨站请求伪造(CSRF)

WWBN AVideo 跨站请求伪造漏洞

WWBN AVideo是WWBN团队的一个由PHP编写的视频平台建站系统。 WWBN AVideo 29.0及之前版本存在跨站请求伪造漏洞，该漏洞源于objects/commentDelete.json.php会删除评论但未执行CSRF验证，未调用forbidIfIsUntrustedRequest、未验证CSRF/全局令牌且未检查Origin/Referer，可能导致任何拥有删除评论权限的已验证受害者访问攻击者页面时被诱骗批量删除评论。
