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-2026-46617 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 1.23.0\n- github.com/fission/fission (Go): affected all versions; fixed in 1.23.0\n- github.com/fission/fission (Go): affected all versions; fixed in 1.23.0\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-2026-46617/ (Markdown: https://insights.sbomify.com/CVE-2026-46617/index.md)","id":"CVE-2026-46617","markdown":"https://insights.sbomify.com/CVE-2026-46617/index.md","name":"CVE-2026-46617","record":{"aliases":["GHSA-85g2-pmrx-r49q","GO-2026-5241"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes serverless framework","requires_auth":"none","summary":"User function code inherits fetcher service account privileges, allowing unauthorized reading of all secrets and configmaps in the namespace.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"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. Prior to version 1.23.0, Fission runtime pods were created with ServiceAccountName: fission-fetcher, and the fission-fetcher ServiceAccount was granted namespace-wide get on secrets and configmaps (it needs that to load function code, env vars, and config). The runtime pod's automounted token was reachable from inside the user's function container at /var/run/secrets/kubernetes.io/serviceaccount/token, so user-supplied function code inherited the same Kubernetes API privileges and could read any secret or configmap in the function's namespace — far beyond the Function.spec.secrets allowlist that the function specification suggests.
