# CVE-2025-27507: IDOR Vulnerabilities in ZITADEL's Admin API that Primarily Impact LDAP Configurations

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.6% , percentile 48: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 48% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs an account (high (admin)). Exposure depends on who can log in.
- Only applies if your dependency tree includes github.com/zitadel/zitadel/v2 (Go) < 2.63.8, fixed in 2.63.8 ; github.com/zitadel/zitadel/v2 (Go) >= 2.64.0, < 2.64.5, fixed in 2.64.5 ; github.com/zitadel/zitadel/v2 (Go) >= 2.65.0, < 2.65.6, fixed in 2.65.6 ; github.com/zitadel/zitadel/v2 (Go) >= 2.66.0, < 2.66.11, fixed in 2.66.11 . Check your lockfile, including transitive dependencies.

## What it is

The open-source identity infrastructure software Zitadel allows administrators to disable the user self-registration. ZITADEL's Admin API contains Insecure Direct Object Reference (IDOR) vulnerabilities that allow authenticated users, without specific IAM roles, to modify sensitive settings. While several endpoints are affected, the most critical vulnerability lies in the ability to manipulate LDAP configurations. Customers who do not utilize LDAP for authentication are not at risk from the most severe aspects of this vulnerability. However, upgrading to the patched version to address all identified issues is strongly recommended. This vulnerability is fixed in 2.71.0, 2.70.1, ,2.69.4, 2.68.4, 2.67.8, 2.66.11, 2.65.6, 2.64.5, and 2.63.8.
