In versions 2.11.27 and below, 3.0.0 through 3.4.4 and 3.5.0-rc1, a path traversal vulnerability was discovered in WASM Traefik’s plugin installation mechanism. By supplying a maliciously crafted ZIP archive containing file paths with ../ sequences, an attacker can overwrite arbitrary files on the system outside of the intended plugin directory. This can lead to remote code execution (RCE), privilege escalation, persistence, or denial of service. This is fixed in versions 2.11.28, 3.4.5 and 3.5.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:H/UI:P/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L","score":7.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-22","CWE-30"],"references":["https://github.com/traefik/plugin-service/pull/71","https://github.com/traefik/plugin-service/pull/72","https://github.com/traefik/traefik/commit/5ef853a0c53068f69a6c229a5815a0dc6e0a8800","https://github.com/traefik/traefik/pull/11911","https://github.com/traefik/traefik/releases/tag/v2.11.28"],"products":["traefik:traefik"],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2025-54386","score":0.01269,"percentile":0.69797,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-q6gg-9f92-r9wg","url":"https://osv.dev/vulnerability/GHSA-q6gg-9f92-r9wg","summary":"Traefik Client Plugin's Path Traversal Vulnerability Allows Arbitrary File Overwrite and Remote Code Execution","modified":"2026-09-10T03:50:27.302466486Z","packages":[{"ecosystem":"Go","name":"github.com/traefik/traefik/v2","purl":"pkg:golang/github.com/traefik/traefik/v2","ranges":["<2.11.28"],"fixed":["2.11.28"]},{"ecosystem":"Go","name":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","ranges":["<3.4.5"],"fixed":["3.4.5"]},{"ecosystem":"Go","name":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","ranges":[">=3.5.0-rc1 <3.5.0"],"fixed":["3.5.0"]}]},{"id":"GO-2025-3835","url":"https://osv.dev/vulnerability/GO-2025-3835","summary":"Traefik Client Plugin's Path Traversal Vulnerability Allows Arbitrary File Overwrite and Remote Code Execution in github.com/traefik/traefik","modified":"2026-02-04T02:34:21.339712Z","packages":[{"ecosystem":"Go","name":"github.com/traefik/traefik","purl":"pkg:golang/github.com/traefik/traefik","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/traefik/traefik/v2","purl":"pkg:golang/github.com/traefik/traefik/v2","ranges":["<2.11.28"],"fixed":["2.11.28"]},{"ecosystem":"Go","name":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","ranges":["<3.4.5",">=3.5.0-rc1 <3.5.0"],"fixed":["3.4.5","3.5.0"]}]}],"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).
