An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-22922 exists.\n\nAffected product: Fedoraproject Fedora. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-22922/ (Markdown: https://insights.sbomify.com/CVE-2021-22922/index.md)","id":"CVE-2021-22922","markdown":"https://insights.sbomify.com/CVE-2021-22922/index.md","name":"CVE-2021-22922","record":{"aliases":["ALPINE-CVE-2021-22922","AZL-6361","CLEANSTART-2026-LX97810","CURL-CVE-2021-22922","DEBIAN-CVE-2021-22922","GHSA-975f-fvhv-8mhx","JLSEC-2026-1335"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"curl library","requires_auth":"none","summary":"Attackers can deliver malicious files via compromised metalink servers because curl fails to delete files with hash mismatches, requiring the metalink feature to be enabled.","user_interaction":"required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"curl","vendor":"haxx"},{"product":"cloud_backup","vendor":"netapp"},{"product":"clustered_data_ontap","vendor":"netapp"},{"product":"h300e_firmware","vendor":"netapp"},{"product":"h300s_firmware","vendor":"netapp"},{"product":"h410s_firmware","vendor":"netapp"},{"product":"h500e_firmware","vendor":"netapp"},{"product":"h500s_firmware","vendor":"netapp"},{"product":"h700e_firmware","vendor":"netapp"},{"product":"h700s_firmware","vendor":"netapp"},{"product":"hci_management_node","vendor":"netapp"},{"product":"solidfire","vendor":"netapp"},{"product":"mysql_server","vendor":"oracle"},{"product":"sinec_infrastructure_network_services","vendor":"siemens"},{"product":"universal_forwarder","vendor":"splunk"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-755","name":"Improper Handling of Exceptional Conditions"},{"id":"CWE-840","name":null}],"description":"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.
