Came across an issue where the _EndCentralDirSig aka 0x06054b50 value seems to exist in the zip data itself (which consisted of .XLSX files). The value existed within the last 1024 bytes of the zipped archive that ZipFile.jl seemed to confuse with the End of central directory record (EOCD).
I have crafted a zip file to simulate the failure.
