Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-35435 exists.\n\nAffected product: CISA Thorium. 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-2025-35435/ (Markdown: https://insights.sbomify.com/CVE-2025-35435/index.md)","id":"CVE-2025-35435","markdown":"https://insights.sbomify.com/CVE-2025-35435/index.md","name":"CVE-2025-35435","record":{"aliases":["GHSA-w2x7-fc9j-4572"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CISA Thorium","requires_auth":"low_privilege","summary":"A remote authenticated attacker can crash the CISA Thorium service by providing a zero stream split size, causing a divide-by-zero error.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisa-cg","cpe":[{"product":"thorium","vendor":"cisa"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-369","name":"Divide By Zero"}],"description":"CISA Thorium accepts a stream split size of zero then divides by this value.
