During this final\ncleanup phase, libcurl attempts to access and modify an internal structure\nthat was already freed during the reset operation.","modified":"2026-08-07T20:29:06.668789612Z","published":"2026-08-07T20:11:58.984Z","upstream":["CVE-2026-10536","EUVD-2026-41497","GHSA-wjq8-x4qm-6mmh"],"database_specific":{"license":"CC-BY-4.0","sources":[{"published":"2026-07-03T07:16:23.563Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-10536","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-10536","database_specific":{"status":"Analyzed"},"id":"CVE-2026-10536","imported":"2026-08-07T19:54:38.724Z","modified":"2026-07-07T18:02:03.890Z"},{"url":"https://api.github.com/advisories/GHSA-wjq8-x4qm-6mmh","html_url":"https://github.com/advisories/GHSA-wjq8-x4qm-6mmh","id":"GHSA-wjq8-x4qm-6mmh","imported":"2026-08-07T19:56:07.635Z","modified":"2026-07-07T18:31:40Z","published":"2026-07-03T09:31:24Z"},{"modified":"2026-07-06T18:29:27Z","published":"2026-07-03T06:11:15Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-41497","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-41497","id":"EUVD-2026-41497","imported":"2026-08-07T19:54:48.822Z"}]},"references":[{"type":"WEB","url":"https://curl.se/docs/CVE-2026-10536.html"},{"type":"WEB","url":"https://curl.se/docs/CVE-2026-10536.json"},{"type":"WEB","url":"https://github.com/advisories/GHSA-wjq8-x4qm-6mmh"},{"type":"WEB","url":"https://hackerone.com/reports/3751697"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-10536"}],"affected":[{"package":{"name":"CURL_jll","ecosystem":"Julia","purl":"pkg:julia/CURL_jll?uuid=b21e61f3-bafc-59ac-ab14-4c5c62d6588d"},"ranges":[{"type":"SEMVER","events":[{"introduced":"8.5.0+0"},{"fixed":"8.21.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1197.json"}},{"package":{"name":"LibCURL_jll","ecosystem":"Julia","purl":"pkg:julia/LibCURL_jll?uuid=deac9b47-8bc7-5906-a0fe-35ac56dc84c0"},"ranges":[{"type":"SEMVER","events":[{"introduced":"7.88.1+0"},{"fixed":"8.21.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1197.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:H/I:H/A:H"}]}
