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-2026-123875 in the wild and no public exploit code.\nExposure: An affected version is only exploitable if your software calls respondWithFile(), stream.respondWithFile() or stream.respondWithFD(). Many projects that include it are not exposed.\n\nAffected product: nodejs node. 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.\n   If an affected version is present, also search the code for calls to respondWithFile(), stream.respondWithFile() or stream.respondWithFD() and report whether any exist.\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-2026-123875/ (Markdown: https://insights.sbomify.com/CVE-2026-123875/index.md)","id":"CVE-2026-123875","markdown":"https://insights.sbomify.com/CVE-2026-123875/index.md","name":"CVE-2026-123875","record":{"aliases":["ALPINE-CVE-2026-123875","BELL-CVE-2026-123875","DEBIAN-CVE-2026-123875","GHSA-v6qh-ch8g-j833","UBUNTU-CVE-2026-123875"],"analysis":{"component_type":"library","exploitable_when_present":false,"fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript runtime","requires_auth":"none","requires_specific_call":true,"summary":"Unauthenticated clients can crash Node.js HTTP/2 servers serving files by cancelling file downloads.","user_interaction":"not_required","vuln_class":"null_dereference","vulnerable_functions":["respondWithFile()","stream.respondWithFile()","stream.respondWithFD()"]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"openjs","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"A NULL pointer dereference in Node.js HTTP/2 lets an unauthenticated client crash the server, over both TLS and cleartext, by cancelling file downloads. When the server serves a file with stream.respondWithFile() or stream.respondWithFD() and the client cancels the request, a StreamPipe used for the transfer is torn down in an order that leaves a NULL pointer which is then dereferenced, aborting the process. No crafted frames are needed, and a handful of cancelled requests against a default file-serving handler is enough.
