Which packages are affected by CVE-2025-64431?

CVE-2025-64431 affects the following packages: github.com/zitadel/zitadel (Go), github.com/zitadel/zitadel (Go). Ecosystems affected: Go.

How do I fix CVE-2025-64431?

Update github.com/zitadel/zitadel to 4.6.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-64431 is resolved across your whole dependency graph.

How do I detect CVE-2025-64431 in my Go dependencies?

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

How do I mitigate CVE-2025-64431 if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Is CVE-2025-64431 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-64431 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-2025-64431?

CVE-2025-64431 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 23th 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-2025-64431?

Description

Summary

ZITADEL's Organization V2Beta API contains Insecure Direct Object Reference (IDOR) vulnerabilities that allow authenticated users with specific administrator roles within one organization to access and modify data belonging to other organizations.

Impact

ZITADEL's Organization V2Beta API, intended for managing ZITADEL organizations, contains multiple endpoints that fail to properly authorize authenticated users. An attacker with an administrator role for a specific organization could exploit this to bypass access controls and perform unauthorized actions on other organizations within the same ZITADEL instance.

This could allow an attacker to:

Read organization data, including the name, domains and metadata.
Manipulate (modify) the corresponding organization data.
Delete the corresponding data, up to and including the entire organization.

Note that this vulnerability is limited to organization-level data (name, domains, metadata). No other related data (such as users, projects, applications, etc.) is affected.

Affected Versions

Systems running one of the following versions are affected:

v4.x: 4.0.0-rc.1 through 4.6.2

Patches

The vulnerability has been addressed in the latest release. The patch resolves the issue by correctly validating the caller's permission against the target organization.

v4.x: Upgrade to version 4.6.3 or later.

Workarounds

Upgrading to a patched version is the recommended solution.

If an immediate upgrade is not possible, mitigation can be achieved by disabling the affected Organization V2Beta API endpoints (e.g., /v2beta/organizations/...) at a reverse proxy or Web Application Firewall (WAF) level.
