{"id":"ALPINE-CVE-2021-22922","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":"2026-08-27T22:18:01.461007381Z","published":"2021-08-05T21:15:11.173Z","upstream":["CVE-2021-22922"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2021-22922"}],"affected":[{"package":{"name":"curl","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.27.0"},{"fixed":"7.78.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-22922.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.27.0"},{"fixed":"7.78.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-22922.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.27.0"},{"fixed":"7.78.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-22922.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.27.0"},{"fixed":"7.78.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-22922.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.27.0"},{"fixed":"7.78.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-22922.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.27.0"},{"fixed":"7.78.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-22922.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.27.0"},{"fixed":"7.78.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-22922.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.27.0"},{"fixed":"7.78.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-22922.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.27.0"},{"fixed":"7.78.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-22922.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.27.0"},{"fixed":"7.78.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-22922.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.27.0"},{"fixed":"7.78.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-22922.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.27.0"},{"fixed":"7.78.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-22922.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.27.0"},{"fixed":"7.78.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-22922.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N"}]}
