How severe is CVE-2022-31035?

CVE-2022-31035 has a CVSS score of 9/10, rated CRITICAL. Immediate patching is strongly recommended.

Which packages are affected by CVE-2022-31035?

CVE-2022-31035 affects the following packages: github.com/argoproj/argo-cd (Go), github.com/argoproj/argo-cd/v2 (Go), github.com/argoproj/argo-cd/v2 (Go), github.com/argoproj/argo-cd/v2 (Go), github.com/argoproj/argo-cd/v2 (Go). Ecosystems affected: Go.

How do I fix CVE-2022-31035?

Update github.com/argoproj/argo-cd to 2.1.16 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-31035 is resolved across your whole dependency graph.

How do I detect CVE-2022-31035 in my Go dependencies?

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.

How do I mitigate CVE-2022-31035 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is CVE-2022-31035 actively exploited in the wild?

No public exploit code has been indexed for CVE-2022-31035 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2022-31035?

CVE-2022-31035 has an EPSS (Exploit Prediction Scoring System) score of 1.0%, placing it in the 63th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2022-31035?

CVE-2022-31035 is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2022-31035 published, and has it been updated?

CVE-2022-31035 was published on June 27, 2022 and was last updated on October 28, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Impact

All unpatched versions of Argo CD starting with v1.0.0 are vulnerable to a cross-site scripting (XSS) bug allowing a malicious user to inject a javascript: link in the UI. When clicked by a victim user, the script will execute with the victim's permissions (up to and including admin).

The script would be capable of doing anything which is possible in the UI or via the API, such as creating, modifying, and deleting Kubernetes resources.

Patches

A patch for this vulnerability has been released in the following Argo CD versions:

v2.4.1
v2.3.5
v2.2.10
v2.1.16

Workarounds

There are no completely-safe workarounds besides upgrading.

Mitigations:

Avoid clicking external links presented in the UI. Here is an example of an Application node with an external link:

The link's title is user-configurable. So even if you hover the link, and the tooltip looks safe, the link might be malicious. The only way to be certain that the link is safe is to inspect the page's source.
Carefully limit who has permissions to edit resource manifests (this is configured in RBAC).
