CVE-2025-55191: Repository Credentials Race Condition Crashes Argo CD Server

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.48% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: github.com/argoproj/argo-cd/v2 (Go) 2.14.20; github.com/argoproj/argo-cd/v3 (Go) 3.0.19, 3.1.8, 3.2.0-rc2; govulncheck-vulndb (openSUSE:Leap 15.6) 0.0.20251023T162509-150000.1.110.1.

Low priority for now. Upgrade to github.com/argoproj/argo-cd/v2 (Go) 2.14.20; github.com/argoproj/argo-cd/v3 (Go) 3.0.19, 3.1.8, 3.2.0-rc2; govulncheck-vulndb (openSUSE:Leap 15.6) 0.0.20251023T162509-150000.1.110.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. 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.
