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 recovered key, attackers can forge administrative tokens, enabling unauthorized privilege escalation and access to restricted endpoints. The vulnerability is fixed in version 2.2.0.
AI Analysis
Technical Summary
CVE-2026-1114 affects parisneo/lollms versions from 2.1.0 up to but not including 2.2.0. The vulnerability arises from the use of a weak secret key for JWT signing, which can be brute-forced offline. Once the secret key is recovered, an attacker can modify JWT payloads and resign them to impersonate administrative users, bypassing access controls. This leads to unauthorized privilege escalation and access to restricted functionality. The CVSS v3.0 score is 9.8, indicating critical severity. The issue is resolved in version 2.2.0.
Potential Impact
An attacker can recover the weak JWT signing secret key via offline brute-force, allowing them to forge administrative tokens. This enables unauthorized privilege escalation and access to restricted endpoints, potentially compromising confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
Upgrade parisneo/lollms to version 2.2.0 or later, where the vulnerability is fixed. No other mitigation guidance is provided. Patch status is confirmed by the version update.
