CyberRota Analysis
AI-GeneratedMISP versions up to 2.5.45 are vulnerable due to the inline serving of uploaded SVG images without a restrictive browser sandbox, allowing for potential execution of malicious scripts when the SVG is directly accessed or embedded. This vulnerability poses a risk to users' sessions, particularly in contexts such as organization logos and event-report images. Organizations using affected versions should prioritize patching to mitigate the risk of session hijacking and other exploits.

Original NVD Description
Affected versions of MISP serve uploaded SVG images inline without a restrictive browser sandbox. The commit explains that SVG files are XML documents rather than passive bitmap images. While scripts inside SVG do not execute when the SVG is rendered through a normal <img>, they can execute when the SVG is navigated to directly or embedded as a document. In that case, malicious <script> elements, event handlers, or javascript: URLs execute on the MISP origin with the viewer’s session. The affected use cases include: - organisation SVG logos; - event-report SVG pictures. Importantly, the vulnerable behavior is on the serve path, not merely the upload path: the patch notes that a malicious SVG uploaded while SVG support was enabled could remain dangerous even after uploads were later disabled. Version affected: ≤2.5.45
