Affected versions of MISP serve uploaded SVG images inline without a restrictive browser sandbox.<\/p>\n
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 , they can execute when the SVG is navigated to directly or embedded as a document. In that case, malicious elements, event handlers, or javascript: URLs execute on the MISP origin with the viewer\u2019s session.<\/p>\n
The affected use cases include:<\/p>\n
\u2003- organisation SVG logos;
\n\u2003-\u00a0event-report SVG pictures.<\/p>\n
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.<\/p>\n
