CVE-2026-120066

MEDIUMCVSS 5.3/10

Last modified

CVE-2026-120066 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. On Unix-like systems, when logging is enabled, psqlODBC creates its log files in /tmp by default, named from the program name, user name, and process ID, with the default permissions, typically world-readable, and follows symbolic links when opening them. A local user can read query text and data from another user's logs, and can place a symbolic link at the predictable path so that the driver appends log data to a file of the attacker's choosing with the victim's privileges.
