Exploitation Status

No confirmed exploitation observed yet

  • A successful exploit gives an attacker total control of the affected component, not partial access.
  • CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

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-2025-47933 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 377,636 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

This vulnerability allows an attacker to perform arbitrary actions on behalf of the victim via the API, such as creating, modifying, and deleting Kubernetes resources. Due to the improper filtering of URL protocols in the repository page, an attacker can achieve cross-site scripting with permission to edit the repository.

In ui/src/app/shared/components/urls.ts, the following code exists to parse the repository URL.

https://github.com/argoproj/argo-cd/blob/0ae5882d5ae9fe88efc51f65ca8543fb8c3a0aa1/ui/src/app/shared/components/urls.ts#L14-L26

Since this code doesn't validate the protocol of repository URLs, it's possible to inject javascript: URLs here.

https://github.com/argoproj/argo-cd/blob/0ae5882d5ae9fe88efc51f65ca8543fb8c3a0aa1/ui/src/app/shared/components/repo.tsx#L5-L7

As the return value of this function is used in the href attribute of the a tag, it's possible to achieve cross-site scripting by using javascript: URLs.

Browsers may return the proper hostname for javascript: URLs, allowing exploitation of this vulnerability.

Patches

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

  • v3.0.4
  • v2.14.13
  • v2.13.8

The patch incorporates a way to validate the URL being passed in. Returning null if the validation fails.

Workarounds

There are no workarounds other than depending on the browser to filter the URL.

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-2025-47933 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-2025-47933 can be triaged on real exposure rather than presence alone.

Tailored to CVE-2025-47933. 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.
