Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-84377 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- litellm (PyPI): affected all versions; fixed in 1.88.6, 1.89.7, 1.90.7, 1.91.5, 1.92.2, 1.93.2, 1.94.3, 1.95.1, 1.96.2\n- litellm (PyPI): affected all versions; fixed in 1.88.6\n- litellm (PyPI): affected all versions; fixed in 1.88.6\n- litellm (PyPI): affected from 1.89.0; fixed in 1.89.7\n- litellm (PyPI): affected from 1.89.0; fixed in 1.89.7\n- litellm (PyPI): affected from 1.90.0; fixed in 1.90.7\n- litellm (PyPI): affected from 1.90.0; fixed in 1.90.7\n- litellm (PyPI): affected from 1.91.0; fixed in 1.91.5\n- litellm (PyPI): affected from 1.91.0; fixed in 1.91.5\n- litellm (PyPI): affected from 1.92.0; fixed in 1.92.2\n- litellm (PyPI): affected from 1.92.0; fixed in 1.92.2\n- litellm (PyPI): affected from 1.93.0; fixed in 1.93.2\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-2026-84377/ (Markdown: https://insights.sbomify.com/CVE-2026-84377/index.md)","id":"CVE-2026-84377","markdown":"https://insights.sbomify.com/CVE-2026-84377/index.md","name":"CVE-2026-84377","record":{"aliases":["CLEANSTART-2026-XQ90781","ECHO-53c1-fa3e-1fea","GHSA-3cv6-jpf6-8222","MINI-48mp-q4hp-rqvg","MINI-5jqp-fg9w-p3mp","MINI-5mxh-gw4p-x9r5","MINI-6pvj-3mfj-wj9r","MINI-78fj-j6w6-768g","MINI-853m-q639-g39f","MINI-8hwp-mvvw-r289","MINI-mpvc-743v-w696","MINI-pj3h-g26w-35m4","MINI-qhqh-j4xm-rh36","MINI-rfwx-7ppx-vcwv","MINI-vp98-xjhc-f9c5","MINI-xfm4-hx3j-4jxh","MINI-xh4h-hfhm-vc4c","PYSEC-2026-4066","openSUSE-SU-2026:11800-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"AI Gateway Proxy","requires_auth":"low_privilege","summary":"Authenticated users can redirect proxy requests to attacker-controlled destinations, exfiltrating provider credentials and accessing internal services.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. Prior to versions 1.88.6 and 1.96.2, any authenticated LiteLLM proxy user could redirect an outbound provider call to a destination the user controls and cause the proxy to send its configured provider credentials to that destination. Request validation in litellm/proxy/auth/auth_utils.py, litellm/proxy/common_request_processing.py, litellm/proxy/health_endpoints/_health_endpoints.py, litellm/proxy/image_endpoints/endpoints.py, and litellm/proxy/litellm_pre_call_utils.py used incomplete checks that did not cover every sensitive parameter or inspect equivalent values across nested request fields, path values, and bracket-notation form data. Routing and credential parameters including api_base, base_url, model_list, fallbacks, and litellm_credential_name could therefore be applied without clearing the operator's stored key, exposing upstream provider credentials and other configured secrets and permitting server-side requests to internal services reachable by the proxy.
