CVE-2026-62231 getgrav CVE debrief
The Grav API plugin (getgrav/grav-plugin-api) before 1.0.6 contains an authorization bypass vulnerability. API keys can be created with a restricted scopes array, but the ApiKeyAuthenticator class never reads or enforces these scopes. It loads and returns the owning user's full account object, allowing a key created with limited scopes (e.g., read-only) to perform any write, delete, or administrative operation the owning user is authorized for. This issue was fixed in version 1.0.6. The vulnerability can be exploited by an attacker with a limited-scope API key, potentially leading to unauthorized access and modification of sensitive data.

Who should care
Users of the Grav API plugin, especially those who have not upgraded to version 1.0.6, should be aware of this vulnerability and take necessary precautions to protect their systems. This includes reviewing and restricting API key scopes, monitoring API usage for suspicious activity, and implementing additional security measures.
Technical summary
The Grav API plugin before 1.0.6 is vulnerable to an authorization bypass. When creating API keys, users can specify a restricted scopes array. However, the ApiKeyAuthenticator class does not enforce these scopes, allowing users with limited-scope keys to perform operations beyond their intended permissions. This vulnerability can be exploited by an attacker with a limited-scope API key, potentially leading to unauthorized access and modification of sensitive data. The issue was fixed in version 1.0.6.
Defensive priority
High
Recommended defensive actions
- Upgrade the Grav API plugin to version 1.0.6 or later
- Review and restrict API key scopes
- Monitor API usage for suspicious activity
- Implement additional security measures, such as IP whitelisting or rate limiting
- Review compensating controls for exposed systems while remediation is scheduled and verified
- Check relevant monitoring, detection, and logs for exposed assets that need extra review
- Track exceptions, retest remediated assets, and close the item only after evidence is documented
