The problem was related to sanitization issues with payloads loading in sandbox mode. Details In the previous versions, there was a potential risk with payloads loading in sandbox mode. The issue occurred due to relative paths not being converted to absolute paths before doing the check for sandbox flag allowing arbitrary files to be read on the filesystem in certain cases when using Nuclei from Go SDK implementation.
