CVE-2024-11098Network attack vector

Stored XSS via unsanitized REST API SVG upload

Published Nov 19, 2024 · Updated Apr 8, 2026

Stored XSS in mr2p SVG Block 1.1.24 and earlier allows remote authenticated users to inject scripts through REST API SVG uploads. The REST API upload handler saves SVG markup without sufficient sanitization to remove executable content, and the file is subsequently served as active markup. Administrator-level access is required, and the script executes when a user accesses the uploaded SVG, enabling actions in that user's browser context.
