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-2025-59425 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- vllm (PyPI): affected all versions; fixed in 0.11.0\n- vllm (PyPI): affected all versions; fixed in 0.11.0\n- vllm (PyPI): affected all versions; fixed in 0.11.0\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-2025-59425/ (Markdown: https://insights.sbomify.com/CVE-2025-59425/index.md)","id":"CVE-2025-59425","markdown":"https://insights.sbomify.com/CVE-2025-59425/index.md","name":"CVE-2025-59425","record":{"aliases":["GHSA-wr9h-g72x-mwhm","PYSEC-2026-2026"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"LLM inference server","requires_auth":"none","summary":"Attackers can bypass authentication in vLLM by exploiting a timing side-channel in API key validation to recover valid keys.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"vllm","vendor":"vllm"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-385","name":"Covert Timing Channel"}],"description":"vLLM is an inference and serving engine for large language models (LLMs). Before version 0.11.0rc2, the API key support in vLLM performs validation using a method that was vulnerable to a timing attack. API key validation uses a string comparison that takes longer the more characters the provided API key gets correct. Data analysis across many attempts could allow an attacker to determine when it finds the next correct character in the key sequence. Deployments relying on vLLM's built-in API key validation are vulnerable to authentication bypass using this technique.
