ParameterPositionPathDescriptionCWE
data:image/bmp;base64,...request body/Dompdf processes an HTML page containing an inlined BMP image via a data URI. Because it fails to validate the header dimensions against the actual image bounds before passing it to the GD library, an attacker can trigger a large memory allocation (memory amplification) by providing a small BMP file with large declared dimensions.CWE-400
