No CVSS score has been assigned to GHSA-cpf4-pmr4-w6cx yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-cpf4-pmr4-w6cx?

GHSA-cpf4-pmr4-w6cx affects the following packages: github.com/zitadel/zitadel (Go), github.com/zitadel/zitadel (Go). Ecosystems affected: Go.

How do I fix GHSA-cpf4-pmr4-w6cx?

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 GHSA-cpf4-pmr4-w6cx is resolved across your whole dependency graph.

How do I detect GHSA-cpf4-pmr4-w6cx 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 GHSA-cpf4-pmr4-w6cx if there is no patch (or I can't update yet)?

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.

How does O3 Security protect against GHSA-cpf4-pmr4-w6cx?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-cpf4-pmr4-w6cx can be triaged on real exposure rather than presence alone.

Is GHSA-cpf4-pmr4-w6cx actively exploited in the wild?

No public exploit code has been indexed for GHSA-cpf4-pmr4-w6cx 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 GHSA-cpf4-pmr4-w6cx?

GHSA-cpf4-pmr4-w6cx has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 21th 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 GHSA-cpf4-pmr4-w6cx?

GHSA-cpf4-pmr4-w6cx is classified as CWE-639 (CWE-639). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-cpf4-pmr4-w6cx published, and has it been updated?

GHSA-cpf4-pmr4-w6cx was published on November 5, 2025 and was last updated on November 17, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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.
