An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-5ccf-884p-4jjq in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- open-webui (PyPI): affected all versions up to 0.3.21; no fix listed\n- open-webui (PyPI): affected all versions up to 0.3.21; no fix listed\n- open-webui (npm): affected all versions up to 0.3.21; no fix listed\n- open-webui (npm): affected all versions up to 0.3.21; 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/GHSA-5ccf-884p-4jjq/ (Markdown: https://insights.sbomify.com/GHSA-5ccf-884p-4jjq/index.md)","id":"GHSA-5ccf-884p-4jjq","markdown":"https://insights.sbomify.com/GHSA-5ccf-884p-4jjq/index.md","name":"GHSA-5ccf-884p-4jjq","record":{"aliases":[],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Open WebUI","requires_auth":"none","summary":"Unauthenticated attackers can cause denial of service in Open WebUI by sending crafted multipart requests that exhaust server resources.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"A Denial of Service (DoS) vulnerability exists in open-webui/open-webui version 0.3.21. This vulnerability affects multiple endpoints, including `/ollama/models/upload`, `/audio/api/v1/transcriptions`, and `/rag/api/v1/doc`. The application processes multipart boundaries without authentication, leading to resource exhaustion. By appending additional characters to the multipart boundary, an attacker can cause the server to parse each byte of the boundary, ultimately leading to service unavailability. This vulnerability can be exploited remotely, resulting in high CPU and memory usage, and rendering the service inaccessible to legitimate users.","ecosystems":["PyPI","npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Open WebUI Unauthenticated Multipart Boundary Denial of Service (DoS) Vulnerability","id":"GHSA-5ccf-884p-4jjq","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":4,"n_references":null,"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.3.21"],"package":"open-webui","purl":null,"source":"GHSA-5ccf-884p-4jjq"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.3.21"],"package":"open-webui","purl":"pkg:pypi/open-webui","source":"GHSA-5ccf-884p-4jjq"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.3.21"],"package":"open-webui","purl":null,"source":"GHSA-5ccf-884p-4jjq"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.3.21"],"package":"open-webui","purl":"pkg:npm/open-webui","source":"GHSA-5ccf-884p-4jjq"}],"products":null,"published":"2025-03-20","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Unauthenticated attackers can cause denial of service in Open WebUI by sending crafted multipart requests that exhaust server resources.","url":"https://insights.sbomify.com/GHSA-5ccf-884p-4jjq/"}
