{"id":"CVE-2026-35454","summary":"Code Extension Marketplace has a Zip Slip Path Traversal","details":"The Code Extension Marketplace is an open-source alternative to the VS Code Marketplace. Prior to 2.4.2, Zip Slip vulnerability in coder/code-marketplace allowed a malicious VSIX file to write arbitrary files outside the extension directory. ExtractZip passed raw zip entry names to a callback that wrote files via filepath.Join with no boundary check; filepath.Join resolved .. components but did not prevent the result from escaping the base path. This vulnerability is fixed in 2.4.2.","aliases":["GHSA-8x9r-hvwg-c55h","GO-2026-5270"],"modified":"2026-07-08T08:12:59.358045782Z","published":"2026-04-06T21:51:53.048Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35454.json","cwe_ids":["CWE-22"],"cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/coder/code-marketplace/releases/tag/v2.4.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35454.json"},{"type":"ADVISORY","url":"https://github.com/coder/code-marketplace/security/advisories/GHSA-8x9r-hvwg-c55h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35454"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/coder/code-marketplace","events":[{"introduced":"0"},{"fixed":"432cdc7463e70a85b35b6dc3f61a624216312896"}],"database_specific":{"cpe":"cpe:2.3:a:coder:code-marketplace:*:*:*:*:*:*:*:*","source":["CPE_RANGE","REFERENCES"],"extracted_events":[{"introduced":"0"},{"last_affected":"2.4.1"}]}}],"versions":["v2.4.1","v2.4.0","v2.3.1","v2.3.0","v2.2.1","v2.2.0","v2.1.0","v2.0.1","v2.0.0","v1.2.2","v1.2.1","v1.2.0","v1.1.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-35454.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
