Versions between 2.1.0 and 2.14.19, 3.2.0-rc1, 3.1.0-rc1 through 3.1.7, and 3.0.0-rc1 through 3.0.18 contain a race condition in the repository credentials handler that can cause the Argo CD server to panic and crash when concurrent operations are performed on the same repository URL. The vulnerability is located in numerous repository related handlers in the util/db/repository_secrets.go file. A valid API token with repositories resource permissions (create, update, or delete actions) is required to trigger the race condition. This vulnerability causes the entire Argo CD server to crash and become unavailable. Attackers can repeatedly and continuously trigger the race condition to maintain a denial-of-service state, disrupting all GitOps operations. This issue is fixed in versions 2.14.20, 3.2.0-rc2, 3.1.8 and 3.0.19.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.3},"cwes":["CWE-362"],"references":["https://github.com/argoproj/argo-cd/commit/701bc50d01c752cad96185f848088d287a97c7b7","https://github.com/argoproj/argo-cd/pull/6103","https://github.com/argoproj/argo-cd/security/advisories/GHSA-g88p-r42r-ppp9"],"products":["argoproj:argo_cd"],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2025-55191","score":0.00483,"percentile":0.41675,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-g88p-r42r-ppp9","url":"https://osv.dev/vulnerability/GHSA-g88p-r42r-ppp9","summary":"Repository Credentials Race Condition Crashes Argo CD Server","modified":"2026-08-24T10:25:33.348750151Z","packages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","ranges":[">=2.1.0 <2.14.20"],"fixed":["2.14.20"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","ranges":[">=3.2.0-rc1 <3.2.0-rc2"],"fixed":["3.2.0-rc2"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","ranges":[">=3.1.0-rc1 <3.1.8"],"fixed":["3.1.8"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","ranges":[">=3.0.0-rc1 <3.0.19"],"fixed":["3.0.19"]}]},{"id":"GO-2025-3994","url":"https://osv.dev/vulnerability/GO-2025-3994","summary":"Repository Credentials Race Condition Crashes Argo CD Server in github.com/argoproj/argo-cd","modified":"2026-08-24T10:25:33.348750151Z","packages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-cd","purl":"pkg:golang/github.com/argoproj/argo-cd","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v2","purl":"pkg:golang/github.com/argoproj/argo-cd/v2","ranges":[">=2.1.0 <2.14.20"],"fixed":["2.14.20"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-cd/v3","purl":"pkg:golang/github.com/argoproj/argo-cd/v3","ranges":[">=3.0.0-rc1 <3.0.19",">=3.1.0-rc1 <3.1.8",">=3.2.0-rc1 <3.2.0-rc2"],"fixed":["3.0.19","3.1.8","3.2.0-rc2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
