An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-6545 exists.\n\nAffected packages and fixed versions:\n- pbkdf2 (npm): affected from 3.0.10; fixed in 3.1.3\n- pbkdf2 (npm): affected from 3.0.10; fixed in 3.1.3\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-2025-6545/ (Markdown: https://insights.sbomify.com/CVE-2025-6545/index.md)","id":"CVE-2025-6545","markdown":"https://insights.sbomify.com/CVE-2025-6545/index.md","name":"CVE-2025-6545","record":{"aliases":["DEBIAN-CVE-2025-6545","GHSA-h7cp-r72f-jxh6","ROOT-APP-NPM-CVE-2025-6545","UBUNTU-CVE-2025-6545","USN-8452-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js pbkdf2 library","requires_auth":"none","summary":"The pbkdf2 library returns predictable zero-filled memory for unsupported algorithms, enabling signature spoofing in Node.js applications.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"harborist","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:H/VA:N/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper Input Validation vulnerability in pbkdf2 allows Signature Spoofing by Improper Validation.
