Doc Text:
A flaw was found in tsParticles. The automated release workflow interpolates release note text directly into a shell command without proper sanitization. A remote attacker or contributor can exploit this vulnerability by submitting content containing shell control characters, leading to arbitrary code execution within the automated build environment when a maintainer initiates a release. Successful exploitation could allow an attacker to modify released artifacts or compromise workflow tokens with elevated permissions.

Description OSIDB Bzimport 2026-11-05 22:18:40 UTC
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.
