{"schema":"threatline.record/2","record":{"id":"CVE-2026-115917","aliases":["GHSA-vvpg-rrww-wpmh"],"summary":"vLLM: Permissive default CORS origins allow cross-origin requests to the vLLM HTTP server","details":"vLLM is an inference and serving engine for large language models. Prior to 0.32.0, the OpenAI-compatible server configures Starlette CORSMiddleware with allowed_origins set to a wildcard by default. A malicious web page can use a victim's browser to reach an unauthenticated vLLM server on localhost, an internal network, or a VPN, call endpoints including GET /v1/models and POST /v1/chat/completions, consume GPU resources, and read responses. Cookie-based cross-site request forgery does not apply because credentials are disabled by default, and deployments requiring bearer authentication are exposed only when the caller already has a usable token. This issue is fixed in version 0.32.0.","categories":["Unclassified"],"product":"vllm","vendor":"vllm-project","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115917","source_modified_at":"2026-10-26T17:20:09.065Z","fetched_at":"2026-10-26T19:10:57.178988Z","product":"vllm","vendor":"vllm-project","versions":[{"version":"< 0.32.0","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":3.4,"severity":"Low","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-26T17:20:09.065Z","modified_at":"2026-10-26T17:20:09.065Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-115917","fetched_at":"2026-10-26T19:10:57.178988Z","source_modified_at":"2026-10-26T17:20:09.065Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-vvpg-rrww-wpmh","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/vllm-project/vllm/pull/61009","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/vllm-project/vllm/commit/fcae5c98870ff2c20659731dce7ba3a3ff0d48aa","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/vllm-project/vllm/releases/tag/v0.32.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-26T17:20:09.065Z","content_hash":"5adbac46205f449ee1e2ce84632b813ab3149969795d4aebf456bae9e249f33d"}}
