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.","cvss_v4":{"vector":"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","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5},"cwes":["CWE-22"],"references":["https://github.com/coder/code-marketplace/releases/tag/v2.4.2","https://github.com/coder/code-marketplace/security/advisories/GHSA-8x9r-hvwg-c55h"],"products":["coder:code-marketplace"],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-35454","score":0.00343,"percentile":0.27905,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8x9r-hvwg-c55h","url":"https://osv.dev/vulnerability/GHSA-8x9r-hvwg-c55h","summary":"Code Extension Marketplace: Zip Slip Path Traversal","modified":"2026-06-25T19:56:08.232001451Z","packages":[{"ecosystem":"Go","name":"github.com/coder/code-marketplace","purl":"pkg:golang/github.com/coder/code-marketplace","ranges":["<1.2.3-0.20260402184705-988440dee05f"],"fixed":["1.2.3-0.20260402184705-988440dee05f"]}]},{"id":"GO-2026-5270","url":"https://osv.dev/vulnerability/GO-2026-5270","summary":"Code Extension Marketplace: Zip Slip Path Traversal in github.com/coder/code-marketplace","modified":"2026-06-25T19:45:23.135910625Z","packages":[{"ecosystem":"Go","name":"github.com/coder/code-marketplace","purl":"pkg:golang/github.com/coder/code-marketplace","ranges":["<1.2.3-0.20260402184705-988440dee05f"],"fixed":["1.2.3-0.20260402184705-988440dee05f"]}]}],"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).
