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-2011-4121 in the wild and no public exploit code.\n\nAffected product: Ruby-Lang Ruby. 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-2011-4121/ (Markdown: https://insights.sbomify.com/CVE-2011-4121/index.md)","id":"CVE-2011-4121","markdown":"https://insights.sbomify.com/CVE-2011-4121/index.md","name":"CVE-2011-4121","record":{"aliases":["GHSA-mjg4-5rfj-952f"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby OpenSSL extension","requires_auth":"none","summary":"The Ruby OpenSSL extension generated weak RSA keys with an exponent of 1, allowing attackers to bypass integrity checks or corrupt services relying on these keys.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ruby","vendor":"ruby-lang"}],"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":"The OpenSSL extension of Ruby (Git trunk) versions after 2011-09-01 up to 2011-11-03 always generated an exponent value of '1' to be used for private RSA key generation.
