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-2026-93355 exists.\n\nAffected product: BerriAI litellm. 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-2026-93355/ (Markdown: https://insights.sbomify.com/CVE-2026-93355/index.md)","id":"CVE-2026-93355","markdown":"https://insights.sbomify.com/CVE-2026-93355/index.md","name":"CVE-2026-93355","record":{"aliases":["GHSA-g83g-3c4g-cfm5","MINI-26rm-gjvm-c352","MINI-39w7-pm94-64hm","MINI-442h-284g-gccj","MINI-5vhj-w45m-p7gp","MINI-5vxj-9vxx-4p6v","MINI-7283-48j3-7gqq","MINI-gmcj-27q7-m8xv","MINI-h3fj-rr29-jg99","MINI-q3h4-9v7f-pw74","MINI-v49x-pc3g-4vh5","MINI-v8qr-mp6x-x4jr","MINI-w2mp-9c29-mj7g","MINI-xwgm-whvj-xpx8"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"LiteLLM authentication library","requires_auth":"low_privilege","summary":"Attackers can impersonate any user and gain admin privileges by exploiting unverified email claims in JWT authentication, leading to unauthorized access to API keys and user management.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1390","name":"Weak Authentication"}],"description":"LiteLLM contains a weak authentication vulnerability that allows an attacker holding a valid JWT from the configured identity provider to authenticate as any existing user by exploiting an email-based fallback lookup in the JWT authentication flow without verifying the email_verified claim.
