CVE-2026-120067: psqlODBC stack buffer overflow copying ctid and oid values for updatable cursors

MediumCVSS 5.9 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 23/100)

  • 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: 0.34% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. 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

For updatable cursors, which are enabled by default, psqlODBC adds hidden ctid and, for tables with OIDs, oid columns to the query. It copies each value into a 32-byte stack buffer using the length the server sent, without checking it against the buffer size, so a value of 32 bytes or more writes past the buffer. A server not trusted under current SSL settings can send such a value. So can any database user who can create a view with its own column named ctid that the application reads with an updatable cursor. Builds with _FORTIFY_SOURCE abort; other builds overwrite adjacent stack memory. Versions before psqlODBC 18.00.0006 are affected.
