pdfme pdf-lib versions before 5.5.10 contain an unbounded buffer growth vulnerability in the DecodeStream.ensureBuffer() method that allows attackers to cause denial of service by supplying a crafted PDF with a FlateDecode stream containing a decompression bomb. Attackers can upload a small compressed PDF that decompresses to hundreds of megabytes, exhausting memory and crashing the Node.js process or freezing browser tabs during PDF parsing.
