{"id":"JLSEC-2026-1335","details":"When curl is instructed to download content using the metalink feature, thecontents is verified against a hash provided in the metalink XML file.The metalink XML file points out to the client how to get the same contentfrom a set of different URLs, potentially hosted by different servers and theclient can then download the file from one or several of them. In a serial orparallel manner.If one of the servers hosting the contents has been breached and the contentsof the specific file on that server is replaced with a modified payload, curlshould detect this when the hash of the file mismatches after a completeddownload. It should remove the contents and instead try getting the contentsfrom another URL. This is not done, and instead such a hash mismatch is onlymentioned in text and the potentially malicious content is kept in the file ondisk.","modified":"2026-08-17T13:30:03.054944600Z","published":"2026-08-17T13:15:13.400Z","upstream":["CVE-2021-22922"],"database_specific":{"license":"CC-BY-4.0","sources":[{"html_url":"https://nvd.nist.gov/vuln/detail/CVE-2021-22922","database_specific":{"status":"Modified"},"id":"CVE-2021-22922","imported":"2026-08-16T08:05:12.477Z","modified":"2026-06-17T03:38:01.807Z","published":"2021-08-05T21:15:11.173Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2021-22922"}]},"references":[{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf"},{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf"},{"type":"WEB","url":"https://hackerone.com/reports/1213175"},{"type":"WEB","url":"https://hackerone.com/reports/1213175"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r61db8e7dcb56dc000a5387a88f7a473bacec5ee01b9ff3f55308aacc%40%3Cdev.kafka.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r61db8e7dcb56dc000a5387a88f7a473bacec5ee01b9ff3f55308aacc%40%3Cdev.kafka.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r61db8e7dcb56dc000a5387a88f7a473bacec5ee01b9ff3f55308aacc%40%3Cusers.kafka.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r61db8e7dcb56dc000a5387a88f7a473bacec5ee01b9ff3f55308aacc%40%3Cusers.kafka.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rbf4ce74b0d1fa9810dec50ba3ace0caeea677af7c27a97111c06ccb7%40%3Cdev.kafka.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rbf4ce74b0d1fa9810dec50ba3ace0caeea677af7c27a97111c06ccb7%40%3Cdev.kafka.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rbf4ce74b0d1fa9810dec50ba3ace0caeea677af7c27a97111c06ccb7%40%3Cusers.kafka.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rbf4ce74b0d1fa9810dec50ba3ace0caeea677af7c27a97111c06ccb7%40%3Cusers.kafka.apache.org%3E"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FRUCW2UVNYUDZF72DQLFQR4PJEC6CF7V/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FRUCW2UVNYUDZF72DQLFQR4PJEC6CF7V/"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202212-01"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202212-01"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20210902-0003/"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20210902-0003/"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpuoct2021.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpuoct2021.html"}],"affected":[{"package":{"name":"LibCURL_jll","ecosystem":"Julia","purl":"pkg:julia/LibCURL_jll?uuid=deac9b47-8bc7-5906-a0fe-35ac56dc84c0"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"7.81.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1335.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V2","score":"AV:N/AC:M/Au:N/C:N/I:P/A:N","source":"NVD"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","source":"NVD"}]}
