EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

How urgent is this, really

CVE-2022-41354 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.

Where this sits among everything scored

Of 377,333 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description

Impact

All versions of Argo CD starting with v0.5.0 are vulnerable to an information disclosure bug allowing unauthorized users to enumerate application names by inspecting API error messages. An attacker could use the discovered application names as the starting point of another attack. For example, the attacker might use their knowledge of an application name to convince an administrator to grant higher privileges (social engineering).

Many Argo CD API endpoints accept an application name as the only parameter. Since Argo CD RBAC requires both the application name and its configured project name (and, if apps-in-any-namespace is enabled, the application's namespace), Argo CD fetches the requested application before performing the RBAC check. If the application does not exist, the API returns a "not found". If the application does exist, and the user does not have access, the API returns an "unauthorized" error. By trial and error, an attacker can infer which applications exist and which do not.

Note that application resources are not fetched for API calls from unauthenticated users. If your Argo CD instance is accessible from the public internet, unauthenticated users will not be able to cause Argo CD to make Kubernetes API calls.

The patch changes API behavior to return "unauthorized" both when the application is missing and when the user is not authorized to access it. This change in API behavior may impact API clients. Check your code to make sure it will handle the new API behavior properly.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/argoproj/argo-cd, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    No patched version of github.com/argoproj/argo-cd has shipped for CVE-2022-41354 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2022-41354 can be triaged on real exposure rather than presence alone.

Tailored to CVE-2022-41354. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
