Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-26056 exists.\n\nAffected packages and fixed versions:\n- github.com/yokecd/yoke (Go): affected all versions; no fix listed\n- github.com/yokecd/yoke (Go): affected all versions up to 0.19.0; no fix listed\n- github.com/yokecd/yoke (Go): affected all versions up to 0.19.0; no fix listed\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-2026-26056/ (Markdown: https://insights.sbomify.com/CVE-2026-26056/index.md)","id":"CVE-2026-26056","markdown":"https://insights.sbomify.com/CVE-2026-26056/index.md","name":"CVE-2026-26056","record":{"aliases":["GHSA-wj8p-jj64-h7ff","GO-2026-4493"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes IaC tool","requires_auth":"low_privilege","summary":"Attackers with CR permissions can execute arbitrary WASM code in the Yoke ATC controller, potentially escalating privileges to cluster-admin.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"yoke","vendor":"yokecd"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Yoke is a Helm-inspired infrastructure-as-code (IaC) package deployer.

The ATC controller downloads and executes the WASM module without proper URL validation, enabling attackers to create arbitrary Kubernetes resources or potentially escalate privileges to cluster-admin level.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Arbitrary WASM Code Execution via AnnotationOverrideFlight Injection in Yoke ATC","id":"CVE-2026-26056","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"Skill Scanner Unsecured Network Binding Vulnerability","id":"CVE-2026-26057"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/yokecd/yoke","purl":"pkg:golang/github.com/yokecd/yoke","source":"GO-2026-4493"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["0.19.0"],"package":"github.com/yokecd/yoke","purl":null,"source":"GHSA-wj8p-jj64-h7ff"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["0.19.0"],"package":"github.com/yokecd/yoke","purl":"pkg:golang/github.com/yokecd/yoke","source":"GHSA-wj8p-jj64-h7ff"}],"prev":{"headline":"Unauthenticated Admission Webhook Endpoints in Yoke ATC","id":"CVE-2026-26055"},"products":["yoke"],"published":"2026-02-12","related":[{"cvss_score":7.5,"headline":"Unauthenticated Admission Webhook Endpoints in Yoke ATC","id":"CVE-2026-26055","kev_date_added":null,"published":"2026-02-12"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-12","vendors":["yokecd"]},"summary":"Attackers with CR permissions can execute arbitrary WASM code in the Yoke ATC controller, potentially escalating privileges to cluster-admin.","url":"https://insights.sbomify.com/CVE-2026-26056/"}
