Dool in versions up to 1.3.8 is vulnerable to symlink following when the "--devel" flag is used, as the application opens a log file without the "O_NOFOLLOW" flag. A local attacker can exploit this by creating a symlink at the expected log file path pointing to a sensitive file, causing dool to truncate and overwrite the target file with log data, which is especially impactful if dool is run with elevated privileges.
