{"id":"CVE-2026-75486","summary":"Synk Sweater Comb \u003c 3.8.8 Command Injection via .vervet.yaml Branch Name","details":"Synk Sweater Comb before 3.8.8 contains a command injection vulnerability that allows an attacker who controls the .vervet.yaml configuration file to execute arbitrary OS commands by injecting malicious input into the linters.\u003ckey\u003e.optic-ci.original branch name field. The expectGitBranch() function in src/lint.ts passes the unsanitized branch name directly into child_process.exec() via an unescaped template literal, enabling arbitrary command execution when the lint command is run against the repository.","modified":"2026-08-30T03:48:11.801044873Z","published":"2026-08-28T15:47:21.519Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/75xxx/CVE-2026-75486.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/75xxx/CVE-2026-75486.json"},{"type":"ADVISORY","url":"https://github.com/snyk/sweater-comb/releases/tag/v3.8.8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-75486"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/synk-sweater-comb-command-injection-via-vervet-yaml-branch-name"},{"type":"FIX","url":"https://github.com/snyk/sweater-comb/commit/05a0eec4f2acb9ce6d4814016b475504fc64eab2"},{"type":"FIX","url":"https://github.com/snyk/sweater-comb/pull/743"},{"type":"PACKAGE","url":"https://github.com/snyk/sweater-comb"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/snyk/sweater-comb","events":[{"introduced":"0"},{"fixed":"908af800b2adb2ff90b5a0b938514b0f830f702a"},{"fixed":"05a0eec4f2acb9ce6d4814016b475504fc64eab2"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.8.8"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["v3.8.7","v3.8.6","v3.8.5","v3.8.4","v3.8.3","v3.8.2","v3.8.1","v3.8.0","v3.7.0","v3.6.4","v3.6.3","v3.6.2","v3.6.1","v3.6.0","v3.5.3","v3.5.2","v3.5.1","v3.5.0","v3.4.0","v3.3.1","v3.3.0","v3.2.8","v3.2.7","v3.2.6","v3.2.5","v3.2.4","v3.2.3","v3.2.2","v3.2.1","v3.2.0","v3.1.8","v3.1.7","v3.1.6","v3.1.5","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.1","v3.0.0","v2.11.5","v2.11.4","v2.11.3","v2.11.2","v2.11.1","v2.11.0","v2.10.0","v2.9.2","v2.9.1","v2.9.0","v2.8.6","v2.8.5","v2.8.4","v2.8.3","v2.8.2","v2.8.1","v2.8.0","v2.7.7","v2.7.6","v2.7.5","v2.7.4","v2.7.3","v2.7.2","v2.7.1","v2.7.0","v2.6.2","v2.6.1","v2.6.0","v2.5.3","v2.5.2","v2.5.1","v2.5.0","v2.4.6","v2.4.5","v2.4.4","v2.4.3","v2.4.2","v2.4.1","v2.4.0","v2.3.54","v2.3.53","v2.3.52","v2.3.51","v2.3.50","v2.3.49","v2.3.48","v2.3.47","v2.3.46","v2.3.45","v2.3.44","v2.3.43","v2.3.42","v2.3.41","v2.3.40","v2.3.39","v2.3.38","v2.3.37","v2.3.36","v2.3.35","v2.3.34","v2.3.33","v2.3.32","v2.3.31","v2.3.30","v2.3.29","v2.3.28","v2.3.27","v2.3.26","v2.3.25","v2.3.24","v2.3.23","v2.3.22","v2.3.21","v2.3.20","v2.3.19","v2.3.18","v2.3.17","v2.3.16","v2.3.15","v2.3.14","v2.3.13","v2.3.12","v2.3.11","v2.3.10","v2.3.9","v2.3.8","v2.3.7","v2.3.6","v2.3.5","v2.3.4","common-model-1.2.0","v2.3.3","v2.3.2","v2.3.1","v2.3.0","v2.2.9","v2.2.8","v2.2.7","v2.2.6","v2.2.5","v2.2.4","v2.2.3","v2.2.2","v2.2.1","v2.2.0","v2.1.14","v2.1.13","v2.1.12","v2.1.11","v2.1.10","v2.1.9","v2.1.8","v2.1.7","v2.1.6","v2.1.5","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.4","v1.24.1","v2.0.3","v2.0.2","v2.0.1","v2.0.0","v1.24.0","v1.23.2","v1.23.1","v1.23.0","v1.22.2","v1.22.1","v1.22.0","v1.21.8","v1.21.7","v1.21.6","v1.21.5","v1.21.4","v1.21.3","v1.21.2","v1.21.1","v1.21.0","v1.20.3","v1.20.2","v1.20.1","v1.20.0","common-model-1.1.0","v1.19.2","common-model-1.0.1","v1.19.1","v1.19.0","v1.18.0","v1.17.2","v1.6.0","common-model-1.0.0","v1.17.1","v1.17.0","v1.16.1","v1.16.0","v1.15.8","v1.15.7","v1.15.6","v1.15.5","v1.15.4","v1.15.3","v1.15.2","v1.15.1","v1.14.10","v1.15.0","v1.14.9","2022-05-18","v1.14.8","2022-05-17","v1.14.7","v1.14.6","v1.14.5","2022-05-13","v1.14.4","2022-05-12","v1.14.3","2022-05-03","v1.14.2","2022-04-27","v1.14.1","2022-04-19","v1.14.0","2022-04-14","v1.13.1","2022-04-08","v1.13.0","2022-04-07","v1.12.0","2022-04-05","v1.11.0","2022-03-30","v1.10.2","2022-03-29","v1.10.1","2022-03-25","v1.10.0","2022-03-24","v1.9.0","2022-03-22","v1.8.0","2022-03-21","v1.7.2","v1.7.1","2022-03-18","v1.7.0","2022-03-17","v1.6.2","2022-03-16","v1.6.1","2022-03-15","v1.5.0","2022-03-08","v1.4.0","2022-02-28","v1.3.0","2022-02-23","v1.2.7","2022-02-17","v1.2.6","v1.2.5","2022-02-16","v1.2.4","2022-02-11","v1.2.3","v1.2.2","2022-02-10","v1.2.1","2022-02-09","v1.2.0","2022-02-08","v1.1.1","2022-02-03","v1.1.0","2022-02-02","v1.0.10","2022-01-05","v1.0.9","2021-12-17","v1.0.8","v1.0.7","v1.0.6","v1.0.5","v1.0.4","2021-12-16","v1.0.3","v1.0.2","v1.0.1","v1.0.0","2021-12-15","v0.3.2","v0.3.1","v0.3.0","v0.2.1","v0.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-75486.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
