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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":7.5,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":7.5,"severity":"high","source":"NVD: security-advisories@github.com","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"}],"modifiedAt":1793834278400,"publishedAt":1793830305939,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/tsparticles/tsparticles/security/advisories/GHSA-gw8q-3x59-mjjx"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/tsparticles/tsparticles/pull/5888"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/tsparticles/tsparticles/commit/d3b5672bd61bb847abfa21193c34eabf7aba6896"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/tsparticles/tsparticles/commit/d3b5672bd61bb847abfa21193c34eabf7aba6896"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/tsparticles/tsparticles/pull/5888"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/tsparticles/tsparticles/security/advisories/GHSA-gw8q-3x59-mjjx"}],"remediation":[],"revision":"d8d1331140dea6f48587b43d1cd1ca8c254c677ca395fa5862d70203463e4b69","sources":[{"modifiedAt":1793830305939,"name":"CNA: GitHub_M","retrievedAt":1793833919469,"url":"https://www.cve.org/CVERecord?id=CVE-2026-76826"},{"modifiedAt":1793834278400,"name":"NVD","retrievedAt":1793838309407,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-76826"}],"ssvc":null,"status":"published","title":"tsParticles: Generated release notes can execute shell commands in the stable publish workflow","updatedAt":1793838309407}
