{"apiVersion":"1.0","identifier":"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.","publishedAt":"2026-08-19T16:18:38","lastModifiedAt":"2026-08-19T19:17:22","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-63408","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","epssProbability":0.0036,"riskScore":0.77,"affectedProduct":"Grav API Plugin","affectedVersions":"<1.0.0-rc.16","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-63408","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-63408","en":"https://www.redsauce.net/en/cves/CVE-2026-63408","fr":"https://www.redsauce.net/fr/cves/CVE-2026-63408","pt":"https://www.redsauce.net/pt/cves/CVE-2026-63408","de":"https://www.redsauce.net/de/cves/CVE-2026-63408","sk":"https://www.redsauce.net/sk/cves/CVE-2026-63408","el":"https://www.redsauce.net/el/cves/CVE-2026-63408"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-63408"}}
