CVE-2026-120066: psqlODBC log files are created with default permissions at a predictable path and follow symbolic links

MediumCVSS 5.3 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.11% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: psqlodbc (Debian:14) 1:18.00.0006-1; psqlODBC (openSUSE:Leap 16.0) 18.00.0006-bp160.1.1; psqlODBC (openSUSE:Tumbleweed) 18.00.0006-1.1.

Low priority for now. Upgrade to psqlodbc (Debian:14) 1:18.00.0006-1; psqlODBC (openSUSE:Leap 16.0) 18.00.0006-bp160.1.1; psqlODBC (openSUSE:Tumbleweed) 18.00.0006-1.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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. Versions before psqlODBC 18.00.0006 are affected.
