An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-85008 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- undici (npm): affected from 7.0.0; fixed in 7.29.1\n- undici (npm): affected from 7.0.0; fixed in 7.29.1\n- undici (npm): affected from 8.0.0; fixed in 8.10.2\n- undici (npm): affected from 8.0.0; fixed in 8.10.2\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-2026-85008/ (Markdown: https://insights.sbomify.com/CVE-2026-85008/index.md)","id":"CVE-2026-85008","markdown":"https://insights.sbomify.com/CVE-2026-85008/index.md","name":"CVE-2026-85008","record":{"aliases":["CLEANSTART-2026-AH89272","CLEANSTART-2026-BT10409","CLEANSTART-2026-OB41556","CLSA-2026-1790801425","DEBIAN-CVE-2026-85008","ECHO-db1d-df7f-29b4","GHSA-8436-99hf-9mmv","MINI-497j-8cf3-rx69","MINI-497p-3mm3-23jp","MINI-4r2q-8f8r-6c7v","MINI-557w-f78h-vvqw","MINI-7c9j-gf85-5228","MINI-7x82-82xf-95f9","MINI-f6g9-35wg-vhfm","MINI-hh4q-96x6-2f69","MINI-p2c2-grj3-mqph","MINI-q4mj-hc5p-47jc","MINI-qgmw-rxgp-3w96","MINI-r7x3-r5q9-h8f7","MINI-rc96-frw9-m8jx","MINI-rhq8-m9g6-c9h2","MINI-whgr-vh4r-p6w2","MINI-x6m5-rq4q-8h3x","ROOT-APP-NPM-CVE-2026-85008","UBUNTU-CVE-2026-85008"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js HTTP client","requires_auth":"none","summary":"Attackers can cause state-changing requests to be served from stale cache, bypassing origin checks and modifying data integrity in undici HTTP client.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openjs","cpe":[{"product":"undici","vendor":"nodejs"}],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"undici's cache interceptor documents that only safe HTTP methods are cached, but its logic to skip caching is built by subtracting the configured methods from the set of safe methods, so an unsafe method such as POST, PUT, or DELETE is never placed in the skip list and instead falls through to the full cache-read path. The response-storage gate also lacked a method check, so a response to an unsafe request that is heuristically cacheable or carries an explicit Cache-Control directive is stored and later replayed from cache. Because response headers from a remote origin are untrusted, an origin can answer once with a cacheable status and then have the client's own subsequent state-changing requests to that path served from the stale cache entry without ever reaching the origin, an integrity failure that occurs under the interceptor's default configuration. This affects undici versions from 7.0.0 up to 7.29.1 and from 8.0.0 up to 8.10.2.
