What an attacker can do

The source says because checkpath() in src/lrz.c only rejects '../' sequences unless built with --enable-pubdir, attackers can send files named with absolute paths to overwrite any file writable by the receiving user. Vendor/CNA’s CVSS 4.0 assessment (base score 7.7/10) rates confidentiality, integrity and availability impact as high.
