CVE-2026-76826 PUBLISHED

tsParticles: Generated release notes can execute shell commands in the stable publish workflow

Assigner: GitHub_M
Reserved: 19.08.2026 Published: 04.11.2026 Updated: 04.11.2026

tsParticles is a TypeScript library for creating highly customizable particle animations. From 4.0.0 until 4.3.2, the stable publish workflow interpolates steps.release.outputs.body directly into an echo command in Bash source before writing RAW_RELEASE.md. Contributor-controlled shell metacharacters in generated release-note text can therefore execute when a maintainer starts a stable release, allowing modification of generated artifacts or workspace scripts and affecting later release steps that hold GITHUB_TOKEN and write permissions. This issue is fixed in version 4.3.2.
