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-2026-8769 exists.\n\nAffected packages and fixed versions:\n- @ai-sdk/provider-utils (npm): affected all versions; fixed in 3.0.28\n- @ai-sdk/provider-utils (npm): affected all versions; fixed in 3.0.28\n- @ai-sdk/provider-utils (npm): affected from 4.0.0-beta.10; fixed in 4.0.33\n- @ai-sdk/provider-utils (npm): affected from 4.0.0-beta.10; fixed in 4.0.33\n- @ai-sdk/provider-utils (npm): affected from 5.0.0-beta.0; fixed in 5.0.1\n- @ai-sdk/provider-utils (npm): affected from 5.0.0-beta.0; fixed in 5.0.1\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-2026-8769/ (Markdown: https://insights.sbomify.com/CVE-2026-8769/index.md)","id":"CVE-2026-8769","markdown":"https://insights.sbomify.com/CVE-2026-8769/index.md","name":"CVE-2026-8769","record":{"aliases":["CLEANSTART-2026-ST69641","CLSA-2026-1792161536","CLSA-2026-1793270505","CLSA-2026-1793271692","CLSA-2026-1793272798","CLSA-2026-1793276296","ECHO-183e-2b87-4034","GHSA-866g-f22w-33x8","MINI-2p6w-v23c-vhj2","MINI-3r49-77fj-4xcp","MINI-6x69-p8vw-qj7x","MINI-8gjv-rvp2-qf27","MINI-c8p8-rg85-rc3f","MINI-h53j-rr6g-2qhq","MINI-h7g3-497m-qghq","MINI-q3p8-xrjv-wj7q","MINI-qj9r-56w6-x67p","MINI-qpmr-f63w-qwh2","MINI-vjr7-v5fr-v543","MINI-vx69-3wqp-8x95"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Vercel AI SDK","requires_auth":"low_privilege","summary":"Remote attackers can cause resource consumption and denial of service in the Vercel AI SDK via the response handler functions.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"ai","vendor":"vercel"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-404","name":"Improper Resource Shutdown or Release"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A vulnerability was determined in vercel ai up to 3.0.97.
