CVE-2026-1114: CWE-284 Improper Access Control in parisneo parisneo/lollms
CVE-2026-1114 is a critical vulnerability in parisneo/lollms version 2. 1. 0 caused by improper access control due to a weak secret key used for signing JSON Web Tokens (JWT). This weakness allows an attacker to perform an offline brute-force attack to recover the secret key. With the secret key, the attacker can forge administrative tokens by modifying and resigning JWT payloads, enabling unauthorized privilege escalation and access to restricted endpoints. The vulnerability is fixed in version 2. 2. 0.
AI Analysis
Technical Summary
The vulnerability in parisneo/lollms 2.1.0 arises from the use of a weak secret key for JWT signing, which enables offline brute-force attacks to recover the key. Once obtained, the attacker can create forged JWTs with administrative privileges, bypassing access controls and gaining unauthorized access to restricted functionality. This is classified as CWE-284 (Improper Access Control). The issue is resolved in version 2.2.0.
Potential Impact
Successful exploitation allows an unauthenticated attacker to escalate privileges to administrator level by forging JWT tokens, leading to full compromise of access controls and potential unauthorized access to sensitive or restricted endpoints. The CVSS score of 9.8 reflects critical impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade parisneo/lollms to version 2.2.0 or later, where the issue is resolved by using a stronger secret key for JWT signing. No other mitigation or temporary fix is indicated. Patch status is confirmed by the vendor advisory stating resolution in version 2.2.0.
