An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-51471 exists.\n\nAffected packages and fixed versions:\n- github.com/ollama/ollama (Go): affected all versions; no fix listed\n- github.com/ollama/ollama (Go): affected all versions up to 0.9.6; no fix listed\n- github.com/ollama/ollama (Go): affected all versions up to 0.9.6; no fix listed\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-2025-51471/ (Markdown: https://insights.sbomify.com/CVE-2025-51471/index.md)","id":"CVE-2025-51471","markdown":"https://insights.sbomify.com/CVE-2025-51471/index.md","name":"CVE-2025-51471","record":{"aliases":["CLEANSTART-2026-OA88832","GHSA-x9hg-5q6g-q3jr","GO-2025-3824","MINI-265x-xh5q-74hg"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Ollama LLM server","requires_auth":"none","summary":"Remote attackers can steal authentication tokens via a malicious realm value, enabling access control bypass and data exposure in Ollama.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ollama","vendor":"ollama"}],"cvss":{"score":6.9,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-384","name":"Session Fixation"},{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"Cross-Domain Token Exposure in server.auth.getAuthorizationToken in Ollama 0.6.7 allows remote attackers to steal authentication tokens and bypass access controls via a malicious realm value in a WWW-Authenticate header returned by the /api/pull endpoint.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":"2025-12-24","github_poc":1,"max_poc_stars":2,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-12-24T21:25:13Z","kind":"github_poc","ref":"https://github.com/ajtazer/CVE-2025-51471-POC","stars":2,"title":"This PoC is for educational and authorized security testing purposes only.
