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.","state":0,"publishedAt":"2021-08-05T00:00:00+00:00","modifiedAt":"2026-10-14T10:37:13.873+00:00","affected":[{"ecosystem":"Vendor product","name":"https://github.com/curl/curl","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n/a\",\n                    \"product\": \"https://github.com/curl/curl\",\n                    \"versions\": [\n                        {\n                            \"version\": \"curl 7.27.0  to and including 7.77.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://hackerone.com/reports/1213175","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FRUCW2UVNYUDZF72DQLFQR4PJEC6CF7V/","https://lists.apache.org/thread.html/r61db8e7dcb56dc000a5387a88f7a473bacec5ee01b9ff3f55308aacc%40%3Cdev.kafka.apache.org%3E","https://lists.apache.org/thread.html/r61db8e7dcb56dc000a5387a88f7a473bacec5ee01b9ff3f55308aacc%40%3Cusers.kafka.apache.org%3E","https://lists.apache.org/thread.html/rbf4ce74b0d1fa9810dec50ba3ace0caeea677af7c27a97111c06ccb7%40%3Cusers.kafka.apache.org%3E","https://lists.apache.org/thread.html/rbf4ce74b0d1fa9810dec50ba3ace0caeea677af7c27a97111c06ccb7%40%3Cdev.kafka.apache.org%3E","https://www.oracle.com/security-alerts/cpuoct2021.html","https://security.netapp.com/advisory/ntap-20210902-0003/","https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf","https://security.gentoo.org/glsa/202212-01"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2021-22922","license":"CVE Program Terms of Use","key":"cve-program:CVE-2021-22922","identifiers":["CVE-2021-22922"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
