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-2026-82953/ (Markdown: https://insights.sbomify.com/CVE-2026-82953/index.md)","id":"CVE-2026-82953","markdown":"https://insights.sbomify.com/CVE-2026-82953/index.md","name":"CVE-2026-82953","record":{"aliases":["GHSA-389h-hr53-4f3g"],"analysis":null,"analysis_generated_by":null,"assigner":"apache","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"NULL pointer dereference in the RTMP protocol implementation in Apache bRPC (version \u003c 1.18.0) on all platforms allows remote attackers to crash the server (denial of service) via a crafted createStream command.\n\nRoot Cause:\nWhen an RTMP service rejects a createStream request by returning a null stream from RtmpService::NewStream(), the server sends an error response to the client. If writing this rejection response fails (for example, because the client closes the connection immediately after sending the createStream command), the error-handling path in RtmpChunkStream::OnCreateStream() dereferences the null stream pointer to access stream-\u003e_onfail_id, causing the process to crash.\n\nAffected Scenarios:\nRun an Apache bRPC RTMP server whose RtmpService::NewStream() may return null (i.e., the service rejects createStream requests). A remote client that sends a createStream command and then closes the connection before the rejection response is written can crash the server.\n\nHow to Fix:\n(Choose one of the following options)\n1. Upgrade bRPC to version 1.18.0, which fixes this issue.\n2.
