CVE-2026-56225 Capgo CVE debrief
CVE-2026-56225 is an authorization bypass vulnerability in Capgo's public API key management handlers (get/put/delete/post). API keys created with mode=all but restricted to a single app via limited_to_apps are only checked for limited_to_orgs and not for limited_to_apps, allowing an app-scoped key to enumerate, update, and delete sibling API keys belonging to the same account that are outside its declared app scope. This enables tampering with account-level credentials. The vulnerability has a CVSS score of 8.7 and is classified as HIGH severity. The CVE was published on 2026-06-23T13:16:44.250Z and last modified on 2026-06-23T14:52:58.543Z.

Who should care
Organizations using Capgo's API key management system should be aware of this vulnerability and take immediate action to mitigate the risk. The vulnerability allows an attacker to tamper with account-level credentials, potentially leading to unauthorized access and data breaches. Security teams and administrators responsible for managing API keys and credentials should prioritize patching and updating their systems.
Technical summary
The vulnerability is caused by a lack of proper authorization checks in Capgo's API key management handlers. Specifically, API keys created with mode=all but restricted to a single app via limited_to_apps are not properly validated, allowing an app-scoped key to access and manipulate sibling API keys outside its declared app scope. This is due to the fact that the system only checks for limited_to_orgs and not for limited_to_apps. As a result, an attacker with an app-scoped key can enumerate, update, and delete API keys belonging to the same account, potentially leading to account-level credential tampering.
Defensive priority
High priority should be given to patching and updating Capgo's API key management system to prevent exploitation of this vulnerability. Security teams should also review and monitor API key usage to detect potential suspicious activity.
Recommended defensive actions
- Apply the patch or update to version 12.128.2 or later
- Review and monitor API key usage for suspicious activity
- Implement additional security controls, such as multi-factor authentication and access restrictions
- Conduct a thorough review of API key management policies and procedures
- Consider implementing compensating controls, such as API key rotation and revocation
