CVE-2026-0858 Medium · 6.1 CWE-79 Jan 16, 2026
Cross-site Scripting (XSS) in Plantuml
Versions of the package net.sourceforge.plantuml:plantuml before 1.2026.0 are vulnerable to Stored XSS due to insufficient sanitization of interactive attributes in GraphViz diagrams. As a result, a crafted PlantUML diagram can inject malicious JavaScript into generated SVG output, leading to arbitrary script execution in the context of applications that render the SVG.
