AI Analysis
Technical Summary
CVE-2026-101089 affects Nezha before version 2.2.7. The GET /api/v1/profile API endpoint returns the bcrypt-hashed password field for authenticated users. Because there are no rate limiting or audit trail constraints, attackers with limited privileges can retrieve these hashes and perform offline cracking attacks. The CVSS 4.0 base score is 2.3, reflecting low severity due to attack complexity and privileges required.
Potential Impact
An attacker with at least low privileges and the ability to authenticate can obtain bcrypt-hashed passwords of users. This could lead to offline password cracking attempts. However, the vulnerability does not allow direct password compromise or privilege escalation without successful cracking. No known active exploitation has been reported.
Mitigation Recommendations
Upgrade Nezha to version 2.2.7 or later where this vulnerability is fixed. Since this is an information disclosure issue resolved in the stated fixed version, applying the official patch is the recommended remediation.
