CVE-2026-112184 · Severity: info · Published 2026-10-19

MISP is an open-source threat intelligence platform used by organizations to share and analyze malware samples and indicators of compromise. A reflected cross-site scripting (XSS) vulnerability in the workflow module allows attackers who can control misp-modules service parameters to inject malicious JavaScript that executes in authenticated users' browsers, potentially leading to session hijacking or unauthorized actions on the platform.

## How to fix

- Fixed in 2.5.48

## Technical details

The vulnerability exists in the workflow module's handling of parameter names returned by the misp-modules service. Parameter names are rendered as raw HTML form labels without output encoding, allowing injection of arbitrary HTML or JavaScript. An attacker must either control the misp-modules service or influence its output, and the victim must be authenticated and viewing the affected workflow page for the attack to succeed. The fix involves HTML-escaping parameter names using the h() function before rendering them as form labels.
