Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-40584 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/argoproj/argo-cd/v2 (Go): affected from 2.4.0; fixed in 2.6.15, 2.7.14, 2.8.3\n- github.com/argoproj/argo-cd/v2 (Go): affected from 2.4.0; fixed in 2.6.15\n- github.com/argoproj/argo-cd/v2 (Go): affected from 2.4.0; fixed in 2.6.15\n- github.com/argoproj/argo-cd/v2 (Go): affected from 2.7.0; fixed in 2.7.14\n- github.com/argoproj/argo-cd/v2 (Go): affected from 2.7.0; fixed in 2.7.14\n- github.com/argoproj/argo-cd/v2 (Go): affected from 2.8.0; fixed in 2.8.3\n- github.com/argoproj/argo-cd/v2 (Go): affected from 2.8.0; fixed in 2.8.3\n- argo-cd (Bitnami): affected from 2.4.0; fixed in 2.6.15, 2.7.14, 2.8.3\n- github.com/argoproj/argo-cd (Go): affected all versions; 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-2023-40584/ (Markdown: https://insights.sbomify.com/CVE-2023-40584/index.md)","id":"CVE-2023-40584","markdown":"https://insights.sbomify.com/CVE-2023-40584/index.md","name":"CVE-2023-40584","record":{"aliases":["BIT-argo-cd-2023-40584","GHSA-g687-f2gx-6wm8","GO-2023-2050"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes CD tool","requires_auth":"low_privilege","summary":"A malicious user can cause a denial of service in Argo CD repo-server by uploading a crafted tar.gz archive that exploits unvalidated file sizes and permissions.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"argo_cd","vendor":"argoproj"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Argo CD is a declarative continuous deployment for Kubernetes. All versions of ArgoCD starting from v2.4 have a bug where the ArgoCD repo-server component is vulnerable to a Denial-of-Service attack vector. Specifically, the said component extracts a user-controlled tar.gz file without validating the size of its inner files. As a result, a malicious, low-privileged user can send a malicious tar.gz file that exploits this vulnerability to the repo-server, thereby harming the system's functionality and availability. Additionally, the repo-server is susceptible to another vulnerability due to the fact that it does not check the extracted file permissions before attempting to delete them. Consequently, an attacker can craft a malicious tar.gz archive in a way that prevents the deletion of its inner files when the manifest generation process is completed. A patch for this vulnerability has been released in versions 2.6.15, 2.7.14, and 2.8.3. Users are advised to upgrade. The only way to completely resolve the issue is to upgrade, however users unable to upgrade should configure RBAC (Role-Based Access Control) and provide access for configuring applications only to a limited number of administrators. These administrators should utilize trusted and verified Helm charts.","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":"Denial of Service to Argo CD repo-server","id":"CVE-2023-40584","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"argoproj:argo_cd","products":["argoproj:argo_cd"],"type":"denial_of_service","year":"2023"},"n_packages":9,"n_references":2,"next":{"headline":"Unauthenticated access to Ironic API","id":"CVE-2023-40585"},"packages":[{"ecosystem":"Bitnami","fixed":["2.6.15","2.7.14","2.8.3"],"introduced":["2.4.0","2.7.0","2.8.0"],"last_affected":[],"package":"argo-cd","purl":"pkg:bitnami/argo-cd","source":"BIT-argo-cd-2023-40584"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/argoproj/argo-cd","purl":"pkg:golang/github.com/argoproj/argo-cd","source":"GO-2023-2050"},{"ecosystem":"Go","fixed":["2.6.15","2.7.14","2.8.3"],"introduced":["2.4.0","2.7.0","2.8.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","source":"GO-2023-2050"},{"ecosystem":"Go","fixed":["2.6.15"],"introduced":["2.4.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v2","purl":null,"source":"GHSA-g687-f2gx-6wm8"},{"ecosystem":"Go","fixed":["2.6.15"],"introduced":["2.4.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","source":"GHSA-g687-f2gx-6wm8"},{"ecosystem":"Go","fixed":["2.7.14"],"introduced":["2.7.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v2","purl":null,"source":"GHSA-g687-f2gx-6wm8"},{"ecosystem":"Go","fixed":["2.7.14"],"introduced":["2.7.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","source":"GHSA-g687-f2gx-6wm8"},{"ecosystem":"Go","fixed":["2.8.3"],"introduced":["2.8.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v2","purl":null,"source":"GHSA-g687-f2gx-6wm8"},{"ecosystem":"Go","fixed":["2.8.3"],"introduced":["2.8.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","source":"GHSA-g687-f2gx-6wm8"}],"prev":{"headline":"libp2p nodes vulnerable to OOM attack","id":"CVE-2023-40583"},"products":["argo-cd"],"published":"2023-09-07","related":[{"cvss_score":10,"headline":"Argo CD: Project API Token Exposes Repository Credentials","id":"CVE-2025-55190","kev_date_added":null,"published":"2025-09-04"},{"cvss_score":10,"headline":"Argo CD will blindly trust JWT claims if anonymous access is enabled","id":"CVE-2022-29165","kev_date_added":null,"published":"2022-05-20"},{"cvss_score":9.9,"headline":"Cluster secret might leak in cluster details page in Argo CD","id":"CVE-2023-40029","kev_date_added":null,"published":"2023-09-07"},{"cvss_score":9.9,"headline":"Improper access control allows admin privilege escalation in Argo CD","id":"CVE-2022-24768","kev_date_added":null,"published":"2022-03-23"},{"cvss_score":9.8,"headline":"Argo CD vulnerable to Bypassing of Brute Force Protection via Application Crash and In-Memory Data Loss","id":"CVE-2024-21652","kev_date_added":null,"published":"2024-03-18"},{"cvss_score":9.6,"headline":"ArgoCD ServerSideDiff is vulnerable to Kubernetes Secret Extraction","id":"CVE-2026-42880","kev_date_added":null,"published":"2026-05-07"},{"cvss_score":9.1,"headline":"Argo CD allows cross-site scripting on repositories page","id":"CVE-2025-47933","kev_date_added":null,"published":"2025-05-29"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-26","vendors":["argoproj"]},"summary":"A malicious user can cause a denial of service in Argo CD repo-server by uploading a crafted tar.gz archive that exploits unvalidated file sizes and permissions.","url":"https://insights.sbomify.com/CVE-2023-40584/"}
