An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-37746 in the wild and no public exploit code.\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-2021-37746/ (Markdown: https://insights.sbomify.com/CVE-2021-37746/index.md)","id":"CVE-2021-37746","markdown":"https://insights.sbomify.com/CVE-2021-37746/index.md","name":"CVE-2021-37746","record":{"aliases":["DEBIAN-CVE-2021-37746","GHSA-7cx5-4rpx-pcm3","MGASA-2021-0408","UBUNTU-CVE-2021-37746"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Claws Mail client","requires_auth":"none","summary":"Claws Mail and Sylpheed clients fail to sufficiently validate links before accepting clicks, potentially allowing open redirect attacks.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"claws-mail","vendor":"claws-mail"},{"product":"fedora","vendor":"fedoraproject"},{"product":"sylpheed","vendor":"sylpheed_project"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"textview_uri_security_check in textview.c in Claws Mail before 3.18.0, and Sylpheed through 3.7.0, does not have sufficient link checks before accepting a click.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Open redirect in n/a","id":"CVE-2021-37746","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"open_redirect","year":"2021"},"n_packages":0,"n_references":5,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-37748"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-37743"},"products":["n/a"],"published":"2021-07-30","related":[{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2020-15917","kev_date_added":null,"published":"2020-07-23"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2020-16094","kev_date_added":null,"published":"2020-07-28"},{"cvss_score":7.3,"headline":"Memory corruption in n/a","id":"CVE-2015-8614","kev_date_added":null,"published":"2016-04-11"},{"cvss_score":7.3,"headline":"Memory corruption in n/a","id":"CVE-2015-8708","kev_date_added":null,"published":"2016-04-11"},{"cvss_score":6.8,"headline":"Security feature bypass in n/a","id":"CVE-2014-2576","kev_date_added":null,"published":"2014-10-15"},{"cvss_score":5,"headline":"Null dereference in n/a","id":"CVE-2012-4507","kev_date_added":null,"published":"2012-10-22"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Claws Mail and Sylpheed clients fail to sufficiently validate links before accepting clicks, potentially allowing open redirect attacks.","url":"https://insights.sbomify.com/CVE-2021-37746/"}
