CVE-2026-63408

Description

Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site-s content. Prior to 1.0.0-rc.16, the Grav API plugin JwtAuthenticator::extractBearerToken() accepts a JWT from the token URL query parameter on every /api/v1 route, including state-changing endpoints. Request URLs consequently expose valid access tokens through Apache, proxy, and CDN logs, browser history, and Referer headers, allowing a party with access to those records to reuse the token with the owner-s API privileges. This issue is fixed in version 1.0.0-rc.16.
