An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-50565 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/fission/fission (Go): affected all versions; fixed in 1.24.0\n- github.com/fission/fission (Go): affected all versions; fixed in 1.24.0\n- github.com/fission/fission (Go): affected all versions; fixed in 1.24.0\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-2026-50565/ (Markdown: https://insights.sbomify.com/CVE-2026-50565/index.md)","id":"CVE-2026-50565","markdown":"https://insights.sbomify.com/CVE-2026-50565/index.md","name":"CVE-2026-50565","record":{"aliases":["GHSA-8wcj-mfrc-jx5q","GO-2026-5850"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes serverless framework","requires_auth":"high_privilege","summary":"Fission builder pods automatically mount privileged service account tokens into user-supplied containers, allowing attackers to escalate privileges and access cluster resources.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-538","name":"Insertion of Sensitive Information into Externally-Accessible File or Directory"},{"id":"CWE-269","name":"Improper Privilege Management"},{"id":"CWE-250","name":"Execution with Unnecessary Privileges"}],"description":"Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes.
