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-2023-0430 exists.\n\nAffected product: Mozilla Thunderbird. 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-2023-0430/ (Markdown: https://insights.sbomify.com/CVE-2023-0430/index.md)","id":"CVE-2023-0430","markdown":"https://insights.sbomify.com/CVE-2023-0430/index.md","name":"CVE-2023-0430","record":{"aliases":["ALSA-2023:0606","ALSA-2023:0608","DEBIAN-CVE-2023-0430","GHSA-gg8h-rvx3-6c4c","RHSA-2023:0600","RHSA-2023:0601","RHSA-2023:0602","RHSA-2023:0603","RHSA-2023:0605","RHSA-2023:0606","RHSA-2023:0607","RHSA-2023:0608","RLSA-2023:0606","RLSA-2023:0608"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Thunderbird email client","requires_auth":"none","summary":"Attackers can bypass S/MIME signature validation by using revoked certificates, causing malicious emails to appear valid in Thunderbird.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mozilla","cpe":[{"product":"thunderbird","vendor":"mozilla"}],"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-295","name":"Improper Certificate Validation"}],"description":"Certificate OCSP revocation status was not checked when verifying S/Mime signatures.
