In versions 3.15 and prior, aAn attacker who controls the HTML input can bypass this restriction by embedding a target file path inside an SVG image delivered through a \u00a0data:\u00a0 URI, because dompdf processes the SVG twice and the second pass does not enforce the same protections as the first. When rendering, dompdf hands the SVG to the separate \u00a0php-svg-lib\u00a0 library with external references forced on, and that library has no knowledge of the chroot directory, blocks only the \u00a0phar://\u00a0 scheme, and ultimately reads the referenced file with no path or protocol validation. This lets an external, unauthenticated attacker read arbitrary image files from the server's file system in the default configuration. This issue has been fixed in version 3.16."}], "source": {"advisory": "GHSA-cx96-42px-69fm", "discovery": "UNKNOWN"}}}}
