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-2026-57235 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nokogiri (RubyGems): affected all versions; fixed in 1.19.4\n- nokogiri (RubyGems): affected all versions; fixed in 1.19.4\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-2026-57235/ (Markdown: https://insights.sbomify.com/CVE-2026-57235/index.md)","id":"CVE-2026-57235","markdown":"https://insights.sbomify.com/CVE-2026-57235/index.md","name":"CVE-2026-57235","record":{"aliases":["AZL-91083","BELL-CVE-2026-57235","CLEANSTART-2026-KN35051","DEBIAN-CVE-2026-57235","GHSA-5prr-v3j2-97mh","MINI-32f7-rfj3-qcvh","MINI-4852-846w-pgp3","MINI-55gm-276w-67c9","MINI-74xp-873q-gmph","MINI-85jg-4vpc-qmc7","MINI-hj4p-f65j-r6jm","MINI-mfv2-vvw3-x2pv","MINI-mv8h-68pp-vcj5","UBUNTU-CVE-2026-57235"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby XML library","requires_auth":"none","summary":"An integer overflow in Nokogiri allows out-of-bounds reads via large negative indices, potentially crashing the application.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"nokogiri","vendor":"nokogiri"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri::XML::NodeSet#[] (and its alias #slice) checked the requested index against the node set's bounds using a 32-bit-truncated copy of the index. A large negative index could pass the check and then be used at full width, reading outside the node set's storage. On CRuby this is an out-of-bounds read that typically crashes the process; on JRuby it is not memory-unsafe but returns an incorrect node.
