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-2026-4789 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/kyverno/kyverno (Go): affected from 1.16.0; fixed in 1.17.0\n- github.com/kyverno/kyverno (Go): affected from 1.16.0; fixed in 1.17.0\n- github.com/kyverno/kyverno (Go): affected from 1.16.0; fixed in 1.17.0\n- kyverno (Bitnami): affected from 1.16.0; fixed in 1.17.2\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-2026-4789/ (Markdown: https://insights.sbomify.com/CVE-2026-4789/index.md)","id":"CVE-2026-4789","markdown":"https://insights.sbomify.com/CVE-2026-4789/index.md","name":"CVE-2026-4789","record":{"aliases":["BIT-kyverno-2026-4789","ECHO-f9cf-25f6-fcd8","GHSA-rggm-jjmc-3394","GO-2026-5621","MINI-79f7-x45p-7rph","MINI-8gfv-8g4p-9w22","MINI-cj2p-r577-5pj7","MINI-vxv9-m823-v55m"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes policy engine","requires_auth":"none","summary":"Attackers can exploit unrestricted CEL HTTP functions in Kyverno to perform Server-Side Request Forgery, potentially accessing internal resources.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"kyverno","vendor":"kyverno"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Kyverno, versions 1.16.0 and later, are vulnerable to SSRF due to unrestricted CEL HTTP functions.","ecosystems":["Bitnami","Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"CVE-2026-4789","id":"CVE-2026-4789","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":4,"n_references":3,"next":{"headline":"Cross-site scripting in Premium Addons for Elementor – Powerful Elementor Templates \u0026 Widgets","id":"CVE-2026-4790"},"packages":[{"ecosystem":"Bitnami","fixed":["1.17.2"],"introduced":["1.16.0"],"last_affected":[],"package":"kyverno","purl":"pkg:bitnami/kyverno","source":"BIT-kyverno-2026-4789"},{"ecosystem":"Go","fixed":["1.17.0"],"introduced":["1.16.0"],"last_affected":[],"package":"github.com/kyverno/kyverno","purl":null,"source":"GHSA-rggm-jjmc-3394"},{"ecosystem":"Go","fixed":["1.17.0"],"introduced":["1.16.0"],"last_affected":[],"package":"github.com/kyverno/kyverno","purl":"pkg:golang/github.com/kyverno/kyverno","source":"GHSA-rggm-jjmc-3394"},{"ecosystem":"Go","fixed":["1.17.0"],"introduced":["1.16.0"],"last_affected":[],"package":"github.com/kyverno/kyverno","purl":"pkg:golang/github.com/kyverno/kyverno","source":"GO-2026-5621"}],"prev":{"headline":"Multiple Vulnerabilities affect IBM Tivoli Netcool Impact","id":"CVE-2026-4788"},"products":["Kyverno"],"published":"2026-03-30","related":[{"cvss_score":10,"headline":"Kyverno Cross-Namespace Privilege Escalation via Policy apiCall","id":"CVE-2026-22039","kev_date_added":null,"published":"2026-01-27"},{"cvss_score":8.6,"headline":"Kyverno vulnerable to bypass of policy rules that use namespace selectors in match statements","id":"CVE-2025-46342","kev_date_added":null,"published":"2025-04-30"},{"cvss_score":8.1,"headline":"Kyverno: ServiceAccount token leaked to external servers via apiCall service URL","id":"CVE-2026-41323","kev_date_added":null,"published":"2026-04-24"},{"cvss_score":8.1,"headline":"kyverno apicall servicecall implicit bearer token injection leaks kyverno serviceaccount token","id":"CVE-2026-40868","kev_date_added":null,"published":"2026-04-21"},{"cvss_score":8.1,"headline":"kyverno verifyImages rule bypass possible with malicious proxy/registry","id":"CVE-2022-47633","kev_date_added":null,"published":"2022-12-23"},{"cvss_score":7.7,"headline":"Kyverno: Cross-Namespace Read Bypasses RBAC Isolation (CVE-2026-22039 Incomplete Fix)","id":"CVE-2026-41068","kev_date_added":null,"published":"2026-04-24"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-01","vendors":["Kyverno"]},"summary":"Attackers can exploit unrestricted CEL HTTP functions in Kyverno to perform Server-Side Request Forgery, potentially accessing internal resources.","url":"https://insights.sbomify.com/CVE-2026-4789/"}
