An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-21662 exists.\n\nAffected product: Argoproj Argo Cd. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2024-21662/ (Markdown: https://insights.sbomify.com/CVE-2024-21662/index.md)","id":"CVE-2024-21662","markdown":"https://insights.sbomify.com/CVE-2024-21662/index.md","name":"CVE-2024-21662","record":{"aliases":[],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes GitOps tool","requires_auth":"none","summary":"Attackers can bypass rate limiting and brute force protections by overflowing the login attempt cache, enabling accelerated brute force attacks against the admin account.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"argo_cd","vendor":"argoproj"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Prior to versions 2.8.13, 2.9.9, and 2.10.4, an attacker can effectively bypass the rate limit and brute force protections by exploiting the application's weak cache-based mechanism. This loophole in security can be combined with other vulnerabilities to attack the default admin account. This flaw undermines a patch for CVE-2020-8827 intended to protect against brute-force attacks. The application's brute force protection relies on a cache mechanism that tracks login attempts for each user. This cache is limited to a `defaultMaxCacheSize` of 1000 entries. An attacker can overflow this cache by bombarding it with login attempts for different users, thereby pushing out the admin account's failed attempts and effectively resetting the rate limit for that account. This is a severe vulnerability that enables attackers to perform brute force attacks at an accelerated rate, especially targeting the default admin account. Users should upgrade to version 2.8.13, 2.9.9, or 2.10.4 to receive a patch.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Argo CD vulnerable to Bypassing of Rate Limit and Brute Force Protection Using Cache Overflow","id":"CVE-2024-21662","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"argoproj:argo_cd","products":["argoproj:argo_cd"],"type":"security_feature_bypass","year":"2024"},"n_packages":0,"n_references":5,"next":{"headline":"Remote code execution on ReconServer due to improper input sanitization on the prips command","id":"CVE-2024-21663"},"packages":[],"prev":{"headline":"Argo CD Denial of Service (DoS) Vulnerability Due to Unsafe Array Modification in Multi-threaded Environment","id":"CVE-2024-21661"},"products":["argo-cd"],"published":"2024-03-18","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":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-01","vendors":["argoproj"]},"summary":"Attackers can bypass rate limiting and brute force protections by overflowing the login attempt cache, enabling accelerated brute force attacks against the admin account.","url":"https://insights.sbomify.com/CVE-2024-21662/"}
