Name of the Vulnerable Software and Affected Versions
MISP versions prior to 2.5.48
Description
The remote event preview feature allows CSS injection when a user previews an event from a linked server. The issue occurs because the color value of remote tags is written into an inline CSS style attribute without sufficient validation. While HTML entity encoding is used, the value is still interpreted as CSS, enabling a compromised or malicious linked server to inject arbitrary CSS declarations. An attacker who can modify tags on a linked instance can use this to perform UI manipulation, visual spoofing, or limited information disclosure when a victim views the remote event preview page.
Recommendations
Update to version 2.5.48 or later.
