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-2020-11576 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/argoproj/argo-cd (Go): affected from 1.5.0; fixed in 1.5.1\n- github.com/argoproj/argo-cd (Go): affected from 1.5.0; fixed in 1.5.1\n- github.com/argoproj/argo-cd (Go): affected from 1.5.0; fixed in 1.5.1\n- argo-cd (Bitnami): affected from 1.5.0 up to 1.5.0; 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-2020-11576/ (Markdown: https://insights.sbomify.com/CVE-2020-11576/index.md)","id":"CVE-2020-11576","markdown":"https://insights.sbomify.com/CVE-2020-11576/index.md","name":"CVE-2020-11576","record":{"aliases":["BIT-argo-cd-2020-11576","GHSA-vj54-cjrx-x696","GO-2022-0882"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Argo CD","requires_auth":"none","summary":"Attackers can enumerate valid non-SSO usernames in Argo CD by observing distinct HTTP status codes from the session API endpoint.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"argo_cd","vendor":"argoproj"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-203","name":"Observable Discrepancy"}],"description":"Fixed in v1.5.1, Argo version v1.5.0 was vulnerable to a user-enumeration vulnerability which allowed attackers to determine the usernames of valid (non-SSO) accounts because /api/v1/session returned 401 for an existing username and 404 otherwise.","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":"Observable Discrepancy in Argo","id":"CVE-2020-11576","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"argoproj:argo_cd","products":["argoproj:argo_cd"],"type":"information_disclosure","year":"2020"},"n_packages":4,"n_references":3,"next":{"headline":"Information disclosure in n/a","id":"CVE-2020-11579"},"packages":[{"ecosystem":"Bitnami","fixed":[],"introduced":["1.5.0"],"last_affected":["1.5.0"],"package":"argo-cd","purl":"pkg:bitnami/argo-cd","source":"BIT-argo-cd-2020-11576"},{"ecosystem":"Go","fixed":["1.5.1"],"introduced":["1.5.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd","purl":null,"source":"GHSA-vj54-cjrx-x696"},{"ecosystem":"Go","fixed":["1.5.1"],"introduced":["1.5.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd","purl":"pkg:golang/github.com/argoproj/argo-cd","source":"GHSA-vj54-cjrx-x696"},{"ecosystem":"Go","fixed":["1.5.1"],"introduced":["1.5.0"],"last_affected":[],"package":"github.com/argoproj/argo-cd","purl":"pkg:golang/github.com/argoproj/argo-cd","source":"GO-2022-0882"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2020-11565"},"products":["n/a"],"published":"2020-04-08","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can enumerate valid non-SSO usernames in Argo CD by observing distinct HTTP status codes from the session API endpoint.","url":"https://insights.sbomify.com/CVE-2020-11576/"}
