Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-77459 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/argoproj/argo-cd/v3 (Go): affected from 3.0.0; fixed in 3.3.15, 3.4.10, 3.5.4, 3.6.0-rc2\n- github.com/argoproj/argo-cd/v3 (Go): affected from 3.0.0; fixed in 3.3.15\n- github.com/argoproj/argo-cd/v3 (Go): affected from 3.0.0; fixed in 3.3.15\n- github.com/argoproj/argo-cd/v3 (Go): affected from 3.4.0; fixed in 3.4.10\n- github.com/argoproj/argo-cd/v3 (Go): affected from 3.4.0; fixed in 3.4.10\n- github.com/argoproj/argo-cd/v3 (Go): affected from 3.5.0; fixed in 3.5.4\n- github.com/argoproj/argo-cd/v3 (Go): affected from 3.5.0; fixed in 3.5.4\n- github.com/argoproj/argo-cd/v3 (Go): affected from 3.6.0-rc1; fixed in 3.6.0-rc2\n- github.com/argoproj/argo-cd/v3 (Go): affected from 3.6.0-rc1; fixed in 3.6.0-rc2\n- argo-cd (Bitnami): affected from 2.10.0; fixed in 3.3.15, 3.4.10, 3.5.4\n- github.com/argoproj/argo-cd (Go): affected all versions; no fix listed\n- github.com/argoproj/argo-cd/v2 (Go): affected from 2.10.0; 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-2026-77459/ (Markdown: https://insights.sbomify.com/CVE-2026-77459/index.md)","id":"CVE-2026-77459","markdown":"https://insights.sbomify.com/CVE-2026-77459/index.md","name":"CVE-2026-77459","record":{"aliases":["BIT-argo-cd-2026-77459","ECHO-cd0d-ea4a-763c","GHSA-fmxq-cgp8-87wp","GO-2026-6784","MINI-2g2h-8r69-vrwf","MINI-2hwq-x39g-w4qg","MINI-5cwp-q9wc-g6vq","MINI-6654-3wjh-6w57","MINI-66m4-q2jm-cgc3","MINI-6h6m-gx7c-ph9q","MINI-75fp-58fh-26hw","MINI-798r-9rr8-rrfm","MINI-9qp5-663r-vpfc","MINI-c7cw-85vg-mgj3","MINI-cxjq-642f-j427","MINI-cxr8-365j-4w93","MINI-f7ww-vcgf-gf59","MINI-fxfx-72xf-hpg6","MINI-gp8p-p58x-p897","MINI-gq75-x9mx-vj4c","MINI-j5v8-q9jf-hpmq","MINI-jmxw-v97w-h9jg","MINI-m985-mm38-g6jv","MINI-mmx6-qwq3-2528","MINI-q3fj-pgmx-gjfm","MINI-q95x-48jv-48v9","MINI-r23v-m7m7-2m86","MINI-rmrp-9xv7-m6qf"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes GitOps tool","requires_auth":"low_privilege","summary":"Attackers with Git write access can bypass Argo CD project restrictions via delete hooks, creating resources in forbidden namespaces or clusters.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","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-863","name":"Incorrect Authorization"}],"description":"Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. From 2.10.0 until 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2, Argo CD creates PostDelete resource hooks without applying the AppProject destination and resource authorization checks used during ordinary synchronization. The omitted checks include cluster-scoped and namespaced resource allow/deny lists. A user who can write to an Application's Git repository can commit a delete hook targeting a forbidden namespace, server, group, kind, or resource name, and deletion of the Application causes the application-controller to create that resource with its destination-cluster credentials. The reachable impact is bounded by the controller's cluster access but can include cluster-scoped resources, disallowed namespaces, persistent hook objects, and secondary objects created by a hook Job. PreSync, Sync, PostSync, and SyncFail hooks continue to use the normal project checks. This issue is fixed in versions 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2.","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":"Argo CD: AppProject destination-namespace and resource restrictions bypassed by PreDelete/PostDelete resource hooks","id":"CVE-2026-77459","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":14,"n_references":9,"next":{"headline":"EspoCRM: Mass email template renderer leaks restricted record fields","id":"CVE-2026-77460"},"packages":[{"ecosystem":"Bitnami","fixed":["3.3.15","3.4.10","3.5.4"],"introduced":["2.10.0","3.4.0","3.5.0"],"last_affected":[],"package":"argo-cd","purl":"pkg:bitnami/argo-cd","source":"BIT-argo-cd-2026-77459"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/argoproj/argo-cd","purl":"pkg:golang/github.com/argoproj/argo-cd","source":"GO-2026-6784"},{"ecosystem":"Go","fixed":[],"introduced":["2.10.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","source":"GO-2026-6784"},{"ecosystem":"Go","fixed":[],"introduced":["2.10.0"],"last_affected":["2.14.21"],"package":"github.com/argoproj/argo-cd/v2","purl":null,"source":"GHSA-fmxq-cgp8-87wp"},{"ecosystem":"Go","fixed":[],"introduced":["2.10.0"],"last_affected":["2.14.21"],"package":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","source":"GHSA-fmxq-cgp8-87wp"},{"ecosystem":"Go","fixed":["3.3.15","3.4.10","3.5.4","3.6.0-rc2"],"introduced":["3.0.0","3.4.0","3.5.0","3.6.0-rc1"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","source":"GO-2026-6784"},{"ecosystem":"Go","fixed":["3.3.15"],"introduced":["3.0.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v3","purl":null,"source":"GHSA-fmxq-cgp8-87wp"},{"ecosystem":"Go","fixed":["3.3.15"],"introduced":["3.0.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","source":"GHSA-fmxq-cgp8-87wp"},{"ecosystem":"Go","fixed":["3.4.10"],"introduced":["3.4.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v3","purl":null,"source":"GHSA-fmxq-cgp8-87wp"},{"ecosystem":"Go","fixed":["3.4.10"],"introduced":["3.4.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","source":"GHSA-fmxq-cgp8-87wp"},{"ecosystem":"Go","fixed":["3.5.4"],"introduced":["3.5.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v3","purl":null,"source":"GHSA-fmxq-cgp8-87wp"},{"ecosystem":"Go","fixed":["3.5.4"],"introduced":["3.5.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","source":"GHSA-fmxq-cgp8-87wp"},{"ecosystem":"Go","fixed":["3.6.0-rc2"],"introduced":["3.6.0-rc1"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v3","purl":null,"source":"GHSA-fmxq-cgp8-87wp"},{"ecosystem":"Go","fixed":["3.6.0-rc2"],"introduced":["3.6.0-rc1"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","source":"GHSA-fmxq-cgp8-87wp"}],"prev":{"headline":"exists/2 predicate silently dropped on limited relationships with a parent() filter in AshSql","id":"CVE-2026-77454"},"products":["argo-cd"],"published":"2026-10-13","related":[],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-14","vendors":["argoproj"]},"summary":"Attackers with Git write access can bypass Argo CD project restrictions via delete hooks, creating resources in forbidden namespaces or clusters.","url":"https://insights.sbomify.com/CVE-2026-77459/"}
