CVSS v3.1

The buf.pl script before 2.20 in Irssi before 0.8.20 uses weak permissions for the scrollbuffer dump file created between upgrades, which might allow local users to obtain sensitive information from private chat conversations by reading the file.
Technical Analysis
CVE-2016-7553 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
