Quick assessment

Affected
flowintel flowintel
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.

以下是该漏洞描述的中文翻译： 受影响的 Flowintel 版本在用户修改密码时，未撤销用户已有的认证会话。 这意味着，如果攻击者已经持有有效的会话（例如，来自之前的访问或被盗取的会话令牌），受害者更改密码并不会终止该攻击者的访问权限。该会话将保持可用，直到其自然过期。上游提交直接对此进行了说明：“会话将持续有效直至其到期。” 修复方案是检测密码变更，并在数据库更新后显式调用 。此修复同时应用于 和 两个函数。 受影响的版本：>= 3.3.0

Vulnerability Title
Flowintel Fails to Invalidate Active Sessions After Password Change
Source: CVE Program / CVE List V5
Vulnerability Description
Affected versions of Flowintel do not revoke existing authenticated sessions when a user’s password is changed. This means that if an attacker already possesses a valid session—for example, from prior access or a stolen session token—the victim changing their password does not terminate that attacker’s access. The session remains usable until it expires naturally. The upstream commit describes this directly as: “session keeps working until it expires.” The fix detects password changes and explicitly invokes _invalidate_user_sessions(user.id) after the database update. This is applied in both edit_user_core() and admin_edit_user_core(). Version impacted >=3.3.0
