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.\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-2026-82210/ (Markdown: https://insights.sbomify.com/CVE-2026-82210/index.md)","id":"CVE-2026-82210","markdown":"https://insights.sbomify.com/CVE-2026-82210/index.md","name":"CVE-2026-82210","record":{"aliases":["GHSA-f22p-qq49-qcxh"],"analysis":null,"analysis_generated_by":null,"assigner":"apache","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"Enforceable assertion in the streaming feature of Apache bRPC (version \u003c 1.18.0) on all platforms allows a remote attacker to crash the server process by sending a malformed stream feedback frame.\n\nRoot Cause:\nWhen handling FRAME_TYPE_FEEDBACK frames, bRPC calls Stream::SetRemoteConsumed() which contains CHECK(_cur_buf_size \u003e 0) and unconditionally asserts CHECK(buf.IsEmpty()) on the frame payload. A feedback frame that carries an unexpected payload, or a feedback frame received on a stream where flow control is disabled (cur_buf_size == 0), reaches these assertions. On failure, CHECK failures abort the process, allowing an unauthenticated single client (once a stream is established) to terminate the server and cause a denial of service.\n\nAffected Scenarios:\nUse bRPC server with the streaming control feature (Stream API) served from untrusted network.\n\nHow to Fix:\n1. Upgrade bRPC to version 1.18.0, which fixes this issue.\n2. Apply this patch:  https://github.com/apache/brpc/pull/3494 \n\nThe fix rejects malformed feedback frames with EPROTO and closes only the affected stream instead of crashing the whole process, and it bounds buffer shrinking so cur_buf_size never drops to 0 while flow control is enabled.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Apache bRPC: Remote denial of service (crash) via malformed stream feedback frames","id":"CVE-2026-82210","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Nexi XPay Build \u003c= 7.6.2 - Unauthenticated Payment Completion and Order Key Disclosure","id":"CVE-2026-82211"},"packages":[],"prev":{"headline":"domain-scoped PSL domain cookie","id":"CVE-2026-82209"},"products":["Apache bRPC"],"published":"2026-10-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-21","vendors":["Apache Software Foundation"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-82210/"}
