Short explanation
MISP contains a CSS injection vulnerability in the remote event preview feature. Tag colour values from linked servers are written directly into inline CSS style attributes, potentially leading to UI manipulation or limited information disclosure.
A malicious or compromised linked server can inject arbitrary CSS declarations, enabling visual spoofing and interface manipulation.
What should be done?
- Follow vendor advisories.
- Audit linked server relationships and tag permissions.
- Update affected versions where applicable.

Show the technical text from the sources
MISP contains a CSS injection vulnerability in the remote event preview feature. When a user previews an event from a linked MISP server, the colour value associated with each remote tag is written directly into an inline CSS style attribute without sufficient validation. Although HTML entity encoding is applied, the value is interpreted as CSS within the style attribute, allowing a malicious or compromised linked server to inject arbitrary CSS declarations. An attacker with the ability to create or modify tags on a linked MISP instance can craft a tag colour value containing CSS injection payloads. When a user on the local instance views the event preview, the injected CSS is rendered, potentially allowing UI manipulation, visual spoofing, or limited information disclosure through CSS-based techniques. Preconditions: - A linked MISP server relationship exists between the victim instance and the attacker-controlled instance. - The attacker can create or modify tags on the linked server. - A victim user views the remote event preview page. Affected: <2.5.48.
