CVE-2018-14036

CVE-2018-14036 is a directory traversal vulnerability affecting freedesktop AccountsService versions prior to 0.6.50.

This medium-severity vulnerability (CVSS 6.5) can be exploited remotely with low attack complexity and requires low privileges, leading to high confidentiality impact. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
