CVE-2026-1115
Full vulnerability record from the local CVENow database.
Description
A Stored Cross-Site Scripting (XSS) vulnerability was identified in the social feature of parisneo/lollms, affecting the latest version prior to 2.2.0. The vulnerability exists in the `create_post` function within `backend/routers/social/__init__.py`, where user-provided content is directly assigned to the `DBPost` model without sanitization. This allows attackers to inject and store malicious JavaScript, which is executed in the browsers of users viewing the Home Feed, including administrators. This can lead to account takeover, session hijacking, and wormable attacks. The issue is resolved in version 2.2.0.

"value": "Una vulnerabilidad de cross-site scripting (XSS) almacenado fue identificada en la función social de parisneo/lollms, que afecta a la última versión anterior a la 2.2.0. La vulnerabilidad existe en la función ’create_post’ dentro de ’backend/routers/social/__init__.py’, donde el contenido proporcionado por el usuario es asignado directamente al modelo ’DBPost’ sin sanitización. Esto permite a los atacantes inyectar y almacenar JavaScript malicioso, que se ejecuta en los navegadores de los usuarios que ven el feed de inicio, incluidos los administradores. Esto puede llevar a la toma de control de cuentas, el secuestro de sesión y ataques tipo gusano. El problema se resuelve en la versión 2.2.0."
