| Título | Blossom Blossom ≤ 1.17.1 Improper Input Validation |
|---|
| Descrição | A Stored Cross-Site Scripting (XSS) vulnerability exists in Blossom versions 1.17.1 and earlier. The issue is found in the /article/add endpoint, where user-supplied input for the article title is not properly sanitized or encoded before being stored. The malicious script is subsequently executed in the browser of any user who views the affected content via the /article/temp/h page. This allows remote attackers to inject arbitrary web script or HTML, potentially leading to session hijacking, user redirection, or unauthorized actions on behalf of the victim. |
