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\u2019s 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.”,”published”:”2025-08-01T23:32:21.747Z”,”modified”:”2025-08-04T15:28:06.189Z”,”type”:”cve”,”title”:”Traefik’s Client Plugin is Vulnerable to Path Traversal, Arbitrary File Overwrites and Remote Code Execution”,”source”:”GitHub_M”,”references”:”https:\/\/github.com\/traefik\/traefik\/security\/advisories\/GHSA-q6gg-9f92-r9wg\\nhttps:\/\/github.com\/traefik\/plugin-service\/pull\/71\\nhttps:\/\/github.com\/traefik\/plugin-service\/pull\/72\\nhttps:\/\/github.com\/traefik\/traefik\/pull\/11911\\nhttps:\/\/github.com\/traefik\/traefik\/commit\/5ef853a0c53068f69a6c229a5815a0dc6e0a8800\\nhttps:\/\/github.com\/traefik\/traefik\/releases\/tag\/v2.11.28″,”id”:”CVE-2025-54386″,”bulletinFamily”:””,”cwe”:[“CWE-22″,”CWE-30″],”cvelist”:null,”sourceData”:”traefik traefik \\u003c= 2.11.27, \\u003c 2.11.28\\ntraefik traefik \\u003c= 3.0.0, \\u003c 3.4.5\\ntraefik traefik \\u003e= 3.5.0-rc1, \\u003c 3.5.0-rc2″,”sourceHref”:””,”cvss”:{“score”:7.3,”severity”:”HIGH”,”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”,”version”:”4.0″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”traefik”,”version”:”\\u003c= 2.11.27, \\u003c 2.11.28″,”vendor”:”traefik”,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
