OpenDocMan 2.4.0 through 2.10.0 contains a decompression bomb vulnerability that allows authenticated users to exhaust PHP memory by uploading crafted office documents. Attackers can upload a small ODT, DOCX, or XLSX file whose XML entries decompress to hundreds of megabytes, crashing PHP workers and degrading availability.
