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-2021-42216 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-2021-42216/ (Markdown: https://insights.sbomify.com/CVE-2021-42216/index.md)","id":"CVE-2021-42216","markdown":"https://insights.sbomify.com/CVE-2021-42216/index.md","name":"CVE-2021-42216","record":{"aliases":["GHSA-4f66-7259-g5wm"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"AnonAddy email service","requires_auth":"none","summary":"AnonAddy uses a risky cryptographic algorithm in its verification controller, potentially allowing attackers to bypass security checks.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"anonaddy","vendor":"anonaddy"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-326","name":"Inadequate Encryption Strength"}],"description":"A Broken or Risky Cryptographic Algorithm exists in AnonAddy 0.8.5 via VerificationController.php.","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":"Weak cryptography in n/a","id":"CVE-2021-42216","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-42218"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2021-42205"},"products":["n/a"],"published":"2021-12-15","related":[],"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":"2026-07-09","vendors":["n/a"]},"summary":"AnonAddy uses a risky cryptographic algorithm in its verification controller, potentially allowing attackers to bypass security checks.","url":"https://insights.sbomify.com/CVE-2021-42216/"}
