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 the use of a weak secret key for signing JWTs. This weakness allows attackers to perform offline brute-force attacks to recover the secret key, enabling them to forge administrative tokens and escalate privileges. The vulnerability is resolved in version 2. 2. 0.
AI Analysis
Technical Summary
In parisneo/lollms version 2.1.0, the application uses a weak secret key to sign JSON Web Tokens (JWT), leading to improper access control (CWE-284). An attacker can brute-force the secret key offline, then modify JWT payloads and resign them to impersonate administrators and access restricted endpoints. This vulnerability enables unauthorized privilege escalation. The issue is fixed in version 2.2.0.
Potential Impact
Successful exploitation allows an unauthenticated attacker to recover the JWT signing secret key, forge administrative tokens, impersonate administrators, and gain unauthorized access to restricted functionality. This results in full confidentiality, integrity, and availability impact on the affected system.
Mitigation Recommendations
Upgrade parisneo/lollms to version 2.2.0 or later, where the vulnerability is resolved by using a stronger secret key for JWT signing. No other mitigation guidance is provided. Patch status is not explicitly stated but the vendor has released a fixed version.
