This allows an attacker to embed %2e%2e%2f (URL-encoded ../) sequences in the URL path. These sequences survive the URL parser intact (they contain no literal / characters) but are decoded into directory traversal sequences before the output file is opened for writing. As a result, a crafted URL can cause axel to write downloaded content to arbitrary filesystem paths relative to the current working directory.","state":0,"publishedAt":"2026-10-28T11:26:59.053+00:00","modifiedAt":"2026-10-28T11:26:59.053+00:00","affected":[{"ecosystem":"Vendor product","name":"Axel","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Axel Download Accelerator\",\n                    \"product\": \"Axel\",\n                    \"repo\": \"https://github.com/axel-download-accelerator/axel/\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"2.17.14\",\n                            \"versionType\": \"git\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","score":7,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","score":8.1,"severity":"HIGH"}],"references":["https://github.com/axel-download-accelerator/axel/issues/477","https://github.com/axel-download-accelerator/axel/pull/483/changes/4e76e1a1dd1c4ea11b445e2c45e4ee257c76314e","https://github.com/axel-download-accelerator/axel/milestone/22","https://advisories.orangecyberdefense.com/advisories/167"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-118485","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-118485","identifiers":["CVE-2026-118485"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
