{"id":"JLSEC-2026-1161","summary":"GNU Wget through 1.25.0, fixed in commit dd692d9, contains a heap buffer overflow vulnerability...","details":"GNU Wget through 1.25.0, fixed in commit dd692d9, contains a heap buffer overflow vulnerability in the `html_quote_string()` function in `src/convert.c` that allows a remote attacker to trigger memory corruption by supplying a crafted HTML attribute with a large number of characters requiring entity encoding. A server-supplied HTML attribute causes a signed integer counter to overflow during output size accumulation, resulting in an undersized heap allocation and subsequent heap buffer overflow during the copy phase.","modified":"2026-08-03T21:35:53.966637102Z","published":"2026-08-03T21:18:59.775Z","upstream":["CVE-2026-58472","EUVD-2026-42084","GHSA-332r-8pmf-8m9p"],"database_specific":{"sources":[{"database_specific":{"status":"Analyzed"},"id":"CVE-2026-58472","imported":"2026-08-03T20:01:18.327Z","modified":"2026-07-09T15:58:45.663Z","published":"2026-07-07T21:17:28.873Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-58472","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58472"},{"published":"2026-07-07T21:31:36Z","url":"https://api.github.com/advisories/GHSA-332r-8pmf-8m9p","html_url":"https://github.com/advisories/GHSA-332r-8pmf-8m9p","id":"GHSA-332r-8pmf-8m9p","imported":"2026-08-03T20:01:22.419Z","modified":"2026-07-07T21:31:43Z"},{"modified":"2026-07-14T22:03:12Z","published":"2026-07-07T19:50:53Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-42084","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-42084","id":"EUVD-2026-42084","imported":"2026-08-03T20:01:19.724Z"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://github.com/advisories/GHSA-332r-8pmf-8m9p"},{"type":"WEB","url":"https://gitlab.com/gnuwget/wget/-/commit/dd692d9cea5335b181d877ae917fe6e75587a812"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58472"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/gnu-wget-heap-buffer-overflow-via-html-attribute-encoding"}],"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-2026-1161.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:P/VC:N/VI:L/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"}]}
