CVE-2026-112184 Details
Description
MISP contains a reflected cross-site scripting (XSS) vulnerability in the workflow module interface. Parameter names returned by the misp-modules service are rendered as raw HTML form labels on the workflow module page without output encoding. An attacker who can influence the parameter names reported by the misp-modules service can inject arbitrary HTML or JavaScript that executes in the context of an authenticated MISP user's browser. Preconditions: - The attacker must be able to control or influence parameter names reported by the misp-modules service. - A victim must be authenticated and view the affected workflow module page. Impact: - Execution of arbitrary JavaScript in the victim's browser session. - Potential theft of session tokens, manipulation of the MISP interface, or initiation of unauthorized actions on behalf of the victim. Affected versions: <2.5.48.
A reflected cross-site scripting vulnerability has been identified in MISP versions prior to 2.5.48, specifically within the workflow module interface. This issue arises because parameter names returned by the misp-modules service are displayed as raw HTML form labels on the workflow module page without proper output encoding. An attacker who can manipulate the parameter names reported by the misp-modules service could inject arbitrary HTML or JavaScript that would execute in the context of an authenticated MISP user's browser. The vulnerability could lead to the execution of malicious JavaScript, potentially allowing for the theft of session tokens, manipulation of the MISP interface, or initiation of unauthorized actions on behalf of the victim.
Users can upgrade to MISP version 2.5.50 or later to address this vulnerability.
