CVE-2026-39924— Flarum framework 会话机制问题漏洞

Flarum < 1.8.16 Session Persistence via Improper Access Token Revocation

Flarum before 1.8.16 contains an improper session invalidation vulnerability that allows attackers who hold a valid session token to retain full account access after a victim changes their password, because the access_tokens table is never cleared on password change events. The TokensClearer::clearPasswordTokens() function only removes rows from the password_tokens table while leaving all active session cookies and API bearer tokens intact, including long-lived RememberAccessToken entries, and administrator-forced password resets via the user update endpoint are equally ineffective at revoking attacker-held sessions.

不充分的会话过期机制

Flarum framework 会话机制问题漏洞

Flarum framework是Flarum组织的一款组件框架。 Flarum framework 1.8.16之前版本存在会话机制问题漏洞，该漏洞源于会话失效处理不当，密码更改时未清除access_tokens表中的有效会话令牌，可能导致持有有效会话令牌的攻击者在受害者更改密码后仍保留完整账户访问权限。
