【中文导读】该 CVE 涉及跨站请求伪造（严重风险）。具体受影响产品、版本和修复方案以 NVD/厂商公告为准。 【原始描述】Flag Forge is a Capture The Flag (CTF) platform. In versions from 2.2.0 to before 2.3.1, the FlagForge web application improperly handles session invalidation. Authenticated users can continue to access protected endpoints, such as /api/profile, even after logging out. CSRF tokens are also still valid post-logout, which can allow unauthorized actions. This issue has been patched in version 2.3.1.
