      <title>CVE-2026-53653 — Grav: Unauthenticated denial of service via unbounded image derivative dimensions</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-53653</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; getgrav grav&lt;/p&gt;
&lt;p&gt;Grav is a file-based Web platform. Prior to 1.7.53 and 2.0.0-rc.8, Grav allows an unauthenticated visitor to exhaust server memory and CPU by requesting image derivatives with oversized dimensions through URL query image actions such as forceResize in Grav::fallbackUrl, which passes request parameters to ImageMedium magic actions without a dimension or pixel ceiling. This issue is fixed in versions 1.7.53 and 2.0.0-rc.8.&lt;/p&gt;</description>
