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.\n\n## Affected\n\n- `tsparticles >= 4.0.0, < 4.3.2`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":53,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[]}
