{"id":"JLSEC-2026-406","details":"A path traversal vulnerability exists in curl \u003c8.0.0 SFTP implementation causes the tilde (~) character to be wrongly replaced when used as a prefix in the first path element, in addition to its intended use as the first element to indicate a path relative to the user's home directory. Attackers can exploit this flaw to bypass filtering or execute arbitrary code by crafting a path like /~2/foo while accessing a server with a specific user.","modified":"2026-05-04T13:17:22.270863Z","published":"2026-05-04T13:12:06.605Z","upstream":["CVE-2023-27534"],"database_specific":{"sources":[{"id":"CVE-2023-27534","published":"2023-03-30T20:15:07.427Z","modified":"2025-04-23T17:16:28.313Z","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2023-27534","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2023-27534","database_specific":{"status":"Modified"},"imported":"2026-05-02T08:39:46.830Z"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://hackerone.com/reports/1892351"},{"type":"WEB","url":"https://hackerone.com/reports/1892351"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/03/msg00016.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/03/msg00016.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/36NBD5YLJXXEDZLDGNFCERWRYJQ6LAQW/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/36NBD5YLJXXEDZLDGNFCERWRYJQ6LAQW/"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202310-12"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202310-12"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20230420-0012/"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20230420-0012/"}],"affected":[{"package":{"name":"CURL_jll","ecosystem":"Julia","purl":"pkg:julia/CURL_jll?uuid=b21e61f3-bafc-59ac-ab14-4c5c62d6588d"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"8.5.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-406.json"}},{"package":{"name":"LibCURL_jll","ecosystem":"Julia","purl":"pkg:julia/LibCURL_jll?uuid=deac9b47-8bc7-5906-a0fe-35ac56dc84c0"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"8.0.1+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-406.json"}}],"schema_version":"1.7.5"}
