Improper neutralization of delimiters in the `pattern` input (specifically the command separator `;` and command substitution characters `(` and `)`) mean that arbitrary command injection is possible by modification of the input value used in a workflow. This has the potential for exposure or exfiltration of sensitive information from the workflow runner, such as might be achieved by sending environment variables to an external entity. It is recommended that users update to the patched version `v1.6.12` or the latest release version `v2.0.0`, however remediation may be possible through careful control of workflows and the `pattern` input value used by this action.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","score":6.5},"cwes":["CWE-140"],"references":["https://github.com/fish-shop/syntax-check/commit/91e6817c48ad475542fe4e78139029b036a53b03","https://github.com/fish-shop/syntax-check/commit/c2cb11395e21119ff8d6e7ea050430ee7d6f49ca","https://github.com/fish-shop/syntax-check/security/advisories/GHSA-xj87-mqvh-88w2"],"products":["fish-shop:syntax-check"],"source":"nvd","synced_at":"2026-10-19T21:53:51.317825789+00:00"},"epss":{"cve":"CVE-2024-42482","score":0.00821,"percentile":0.57297,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
