An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-93602 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- rustls-webpki (crates.io): affected from 0.102.0-alpha.0; fixed in 0.103.10\n- rustls-webpki (crates.io): affected from 0.102.0-alpha.0; fixed in 0.103.10\n- rustls-webpki (crates.io): affected from 0.102.0-alpha.0; fixed in 0.103.10\n- rustls-webpki (crates.io): affected from 0.104.0-alpha.1; fixed in 0.104.0-alpha.5\n- rustls-webpki (crates.io): affected from 0.104.0-alpha.1; fixed in 0.104.0-alpha.5\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-2026-93602/ (Markdown: https://insights.sbomify.com/CVE-2026-93602/index.md)","id":"CVE-2026-93602","markdown":"https://insights.sbomify.com/CVE-2026-93602/index.md","name":"CVE-2026-93602","record":{"aliases":["AZL-103463","AZL-103503","AZL-103511","AZL-103524","CLEANSTART-2026-XA32813","DEBIAN-CVE-2026-93602","GHSA-8hrm-p5h4-6vcx","GHSA-pwjx-qhcg-rvj4","MINI-282f-qvjf-gxrr","MINI-36r4-gjmp-v757","MINI-4745-cj29-4r3c","MINI-5g48-p755-pjmf","MINI-5pw2-2c8h-3w7v","MINI-64h2-q2x3-g776","MINI-68w2-c9j7-hvj7","MINI-6r9r-mv59-pvc8","MINI-7h35-4hf2-c82c","MINI-9mmv-2m75-cjfq","MINI-cx84-gqpx-v45c","MINI-fhqm-m7xq-6cf8","MINI-gr9x-w7g6-5j7j","MINI-gwjf-27qf-2whw","MINI-j9vp-2427-372r","MINI-jmwj-r66w-m859","MINI-jpf9-768x-9xx6","MINI-mj6f-4h5m-4396","MINI-qr44-6pw5-8qrm","MINI-vg62-5qj5-2rmv","MINI-wqp9-8qv3-jwfx","MINI-xhq3-2pgv-p2w3","RUSTSEC-2026-0049","UBUNTU-CVE-2026-93602"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Rust TLS library","requires_auth":"high_privilege","summary":"Attackers with a compromised CA can bypass CRL revocation checks in rustls-webpki, allowing revoked certificates to be accepted.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-299","name":"Improper Check for Certificate Revocation"}],"description":"rustls-webpki versions before 0.103.10 and 0.104.0-alpha.5 contain faulty CRL authority-matching logic that compares only the first distributionPoint against each CRL's IssuingDistributionPoint, ignoring additional distributionPoints.
