CVE-2026-11491 is a stored cross-site scripting vulnerability in CodeAstro Human Resource Management System 1.0. The issue exists in the Notice Board Management component's /notice/All_notice file, where the Notice Title parameter is not properly sanitized. An attacker can submit a POST request with malicious SVG code containing an onload JavaScript event, leading to script execution in the context of the victim's browser. This vulnerability can be triggered remotely and the exploit code is publicly available. No official fix or patch has been published as of the data provided.

Successful exploitation allows an attacker to execute arbitrary JavaScript in the context of the affected application for users who view the manipulated notice. This can lead to session hijacking, defacement, or other client-side attacks. The vulnerability requires user interaction (UI:P) and privileges (PR:H) but no authentication bypass or system compromise is indicated. The impact is limited to client-side script execution with medium severity.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider restricting access to the Notice Board Management feature, applying input validation or sanitization on the Notice Title parameter if possible, and monitoring for suspicious activity related to this component. Avoid using untrusted input in the Notice Title field.
