An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-3309 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-3309/ (Markdown: https://insights.sbomify.com/CVE-2021-3309/index.md)","id":"CVE-2021-3309","markdown":"https://insights.sbomify.com/CVE-2021-3309/index.md","name":"CVE-2021-3309","record":{"aliases":["GHSA-pmg3-799q-7mhw"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Wekan LDAP integration","requires_auth":"none","summary":"Wekan's LDAP module fails to validate server certificates against the trust store, allowing attackers to bypass TLS security checks.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"wekan","vendor":"wekan_project"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"packages/wekan-ldap/server/ldap.js in Wekan before 4.87 can process connections even though they are not authorized by the Certification Authority trust store,","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Security feature bypass in n/a","id":"CVE-2021-3309","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Path traversal in n/a","id":"CVE-2021-3310"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2021-3308"},"products":["n/a"],"published":"2021-01-26","related":[{"cvss_score":9.3,"headline":"Wekan has Cross-Board IDOR in Custom Fields Update Endpoints","id":"CVE-2026-30843","kev_date_added":null,"published":"2026-03-06"},{"cvss_score":9.3,"headline":"Wekan Vulnerable to SSRF through Lack of Validation or Filtering in Attachment URL Loading","id":"CVE-2026-30844","kev_date_added":null,"published":"2026-03-06"},{"cvss_score":9.3,"headline":"Wekan Credential Leak via notificationUsers Publication Exposes Password Hashes and Session Tokens","id":"CVE-2026-30847","kev_date_added":null,"published":"2026-03-06"},{"cvss_score":8.8,"headline":"Missing authorization in n/a","id":"CVE-2025-65780","kev_date_added":null,"published":"2025-12-15"},{"cvss_score":8.7,"headline":"Wekan Exposes All Global Webhook Integrations through globalwebhooks Publication","id":"CVE-2026-30846","kev_date_added":null,"published":"2026-03-06"},{"cvss_score":8.7,"headline":"WeKan \u003c 8.19 LDAP Authentication Filter Injection","id":"CVE-2026-25560","kev_date_added":null,"published":"2026-02-07"},{"cvss_score":8.2,"headline":"Denial of service in n/a","id":"CVE-2025-65781","kev_date_added":null,"published":"2025-12-15"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"Wekan's LDAP module fails to validate server certificates against the trust store, allowing attackers to bypass TLS security checks.","url":"https://insights.sbomify.com/CVE-2021-3309/"}
