CVE-2025-32413Network attack vector

Stored XSS via unsanitized biography Markdown

Published Apr 8, 2025 · Updated Apr 8, 2025

Stored cross-site scripting in CIRCL Vulnerability-Lookup before 2.7.1 allows remote authenticated users to execute script via a crafted bio. The profile view passes the stored biography through markdown.markdown and renders the resulting HTML without sanitizing unsafe elements or attributes. An account able to save a bio is required; viewing the profile executes the payload in the viewer's origin, enabling limited data access or modification.
