Quick assessment

Affected
pgadmin.org pgAdmin 4
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

pgAdmin 4 在用户密码变更时未能使该用户现有的会话失效，无论该变更是通过用户自身的“修改密码”对话框完成，还是由管理员在“用户管理”中重置密码。因此，在密码变更之前建立的会话（例如在另一台设备上建立的会话，或由已获取旧密码或会话 Cookie 的人员建立的会话）在密码变更后仍保持登录状态。而用户或管理员执行密码变更操作，正是为了切断此类访问权限。这些会话在过期前一直可用。 修复方案为：每当密码变更时，轮换用户的会话标识符（fs_uniquifier），从而使该用户的所有其他会话被强制登出。执行密码变更操作的

Vulnerability Title
pgAdmin 4: A user's other sessions survive a change of their password
Source: CVE Program / CVE List V5
Vulnerability Description
pgAdmin 4 did not invalidate a user's existing sessions when their password changed, either through the user's own change password dialog or through an administrator resetting it in User Management. A session established before the change, for example on another device or by someone who had obtained the old password or a session cookie, therefore stayed logged in after the change, which is the step a user or administrator takes precisely to cut such access off. It remained usable until it expired. The fix rotates the user's session identifier (fs_uniquifier) whenever the password is changed, so every other session of that user is logged out. The session that made the change is logged in again and keeps its database connections. Saved server passwords, including those for shared servers, are re-encrypted under the new key; any that cannot be decrypted are cleared and the user is told. If re-encryption fails, the sessions are still revoked and the saved passwords are cleared rather than the change failing. This issue affects pgAdmin 4: before 9.19.
