{"id":"JLSEC-2026-1158","summary":"GNU Wget through 1.25.0, fixed in commit 37a40fc, contains a heap buffer underread vulnerability...","details":"GNU Wget through 1.25.0, fixed in commit 37a40fc, contains a heap buffer underread vulnerability in the `clean_metalink_string()` function within `src/metalink.c` that allows a malicious server to trigger memory corruption by serving a Metalink document containing a whitespace-only URL. Attackers can cause the function to decrement a pointer past the start of the buffer when processing an all-whitespace Metalink URL, potentially leading to abnormal program behavior.","modified":"2026-08-03T21:43:58.660769351Z","published":"2026-08-03T21:18:59.775Z","upstream":["CVE-2026-58469","EUVD-2026-42081","GHSA-fxf9-rxpj-26gx"],"database_specific":{"license":"CC-BY-4.0","sources":[{"database_specific":{"status":"Analyzed"},"id":"CVE-2026-58469","imported":"2026-08-03T20:01:18.251Z","modified":"2026-07-09T15:59:43.220Z","published":"2026-07-07T21:17:28.383Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-58469","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58469"},{"id":"GHSA-fxf9-rxpj-26gx","imported":"2026-08-03T20:01:22.721Z","modified":"2026-07-07T21:31:43Z","published":"2026-07-07T21:31:36Z","url":"https://api.github.com/advisories/GHSA-fxf9-rxpj-26gx","html_url":"https://github.com/advisories/GHSA-fxf9-rxpj-26gx"},{"published":"2026-07-07T19:43:34Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-42081","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-42081","id":"EUVD-2026-42081","imported":"2026-08-03T20:01:19.724Z","modified":"2026-07-14T22:03:10Z"}]},"references":[{"type":"WEB","url":"https://github.com/advisories/GHSA-fxf9-rxpj-26gx"},{"type":"WEB","url":"https://gitlab.com/gnuwget/wget/-/commit/37a40fcb450153f69537c7cbc2a7a4fb0b6f7826"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58469"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/gnu-wget-heap-buffer-underread-via-metalink-url-parsing"}],"affected":[{"package":{"name":"wget_jll","ecosystem":"Julia","purl":"pkg:julia/wget_jll?uuid=25883557-5102-5516-a11b-f84f27e871d7"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1158.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"CNA"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","source":"CNA"}]}
