Last modified
CVE-2026-0858 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. 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.. EPSS estimates a 0.30% chance of exploitation in the next 30 days.
