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-2026-50563/ (Markdown: https://insights.sbomify.com/CVE-2026-50563/index.md)","id":"CVE-2026-50563","markdown":"https://insights.sbomify.com/CVE-2026-50563/index.md","name":"CVE-2026-50563","record":{"aliases":["GHSA-v455-mv2v-5g92","GO-2026-5858"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"},{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes.
