Authorization Flaw in Grav API plugin (CVE-2026-62231)
Summary
Vulnerability in Grav API plugin (CVE-2026-62231). Confidential information can be exposed externally. Mitigation: upgrade to 1.0.6 or later.
Original description
The description as published by the source.
The Grav API plugin (getgrav/grav-plugin-api) before 1.0.6 contains an authorization bypass: 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, so a key created with limited scopes (e.g. read-only) can perform any write, delete, or administrative operation the owning user is authorized for. Fixed in 1.0.6.
