It was discovered that Dompdf was not properly validating processed HTML content that referenced PHAR files, which could result in the deserialization of untrusted data. An attacker could possibly use this issue to execute arbitrary code. (CVE-2021-3838)

It was discovered that Dompdf was not properly validating processed HTML content that referenced both a remote base and a local file, which could result in the bypass of a chroot check. An attacker could possibly use this issue to expose sensitive information. (CVE-2022-2400)
