⚡ A sneaky flaw in Docmost could let attackers write arbitrary files just by zipping them up! 🚀 Think of it like an unguarded delivery box—if nobody checks what's inside, anyone can slip in a package that doesn't belong. That’s exactly what’s happening here when the Zip Import Feature doesn’t validate filenames! An attacker could exploit this vulnerability to overwrite important files on the server, potentially leading to data corruption or loss. This could be absolutely devastating for teams relying on Docmost for collaborative documentation, as the trust in the platform could be shattered.
Think of it like an unguarded delivery box—if nobody checks what's inside, anyone can slip in a package that doesn't belong. That’s exactly what’s happening here when the Zip Import Feature doesn’t validate filenames! This vulnerability arises from a lack of validation on filenames during the zip import process, allowing attackers to use Zip Slip techniques to manipulate file paths and write files to arbitrary locations on the server.
