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.","published":"2026-04-06T21:51:53.048Z","modified":"2026-08-05T03:32:32.974100108Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/coder/code-marketplace","fixedVersion":"1.2.3-0.20260402184705-988440dee05f"}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-05T03:32:32.974100108Z"}}
