Detectable: evidence found.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade Red Hat to 3.2.7-r0 or 1.19.1.

An update is now available for Red Hat OpenShift GitOps. Bug Fix(es) and Enhancement(s): * GITOPS-8080 (CVE-2025-58183 openshift-gitops-1/argocd-rhel8: Unbounded allocation when parsing GNU sparse map [gitops-1.19]) * GITOPS-8083 (CVE-2025-58183 openshift-gitops-1/dex-rhel8: Unbounded allocation when parsing GNU sparse map [gitops-1.19]) * GITOPS-7849 (Cherry pick Repo Type Fix to Argo CD 3.1 stream) * GITOPS-7992 (openshift-gitops-operator-metrics-monitor ServiceMonitor is attempting to use a bearerTokenFile configuration in its endpoints definition) * GITOPS-8225 (RC 1.19.0-2 : haproxy replica remains 1 with HA upgrade) * GITOPS-8249 (Prevent argoCD from automatically refreshing to gitops repository ) * GITOPS-8411 (CVE-2025-55190 still blocking due to github.com/argoproj/argo-cd/v2@v2.14.11 in gitops-rhel8:v1.18.1) * GITOPS-8535 (Show All Namespaces or Current Namespace Only option) * GITOPS-8591 (Reciving TargetDown after upgrading GitOps )

Impact

The vulnerability allows an attacker with valid login credentials or a stolen API token to access sensitive repository credentials via the project details API endpoint. This can lead to unauthorized tampering with projects linked to the API token. However, it does not provide full system control or broader administrative privileges. The severity is rated as high due to the confidentiality, integrity, and availability impacts on the affected projects.

Summary

CVE-2025-55190 is an information leak vulnerability in Red Hat OpenShift GitOps (Argo CD component) where the project details API endpoint may unintentionally expose sensitive repository credentials. An attacker must have privileges to create or have stolen an API token to exploit this vulnerability. The impact is limited to tampering with projects associated with the compromised API token and does not grant full system control. Red Hat has issued a security update in OpenShift GitOps v1.19.1 to fix this issue. Additional fixes for related issues and enhancements are included in this update. The vulnerability is tracked under CWE-522 (Insufficiently Protected Credentials) and CWE-770 (Allocation of Resources Without Limits or Throttling).

CWE-522Insufficiently Protected Credentials (opens in a new tab)
Class weaknessOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
Architecture and Design
Use an appropriate security mechanism to protect the credentials.
Architecture and Design
Make appropriate use of cryptography to protect the credentials.
Implementation
Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).

CWE-770Allocation of Resources Without Limits or Throttling (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #25
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
Requirements
Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
Architecture and Design
Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended.
