CVE-2026-14668

8.1 highEPSS 0.3%

High (8.1) in postgresql postgresql. EPSS 0.3% chance of exploitation in the next 30 days.

Type confusion regarding input of PostgreSQL ctid data type selectivity estimator allows an object creator to view a calculation derived from the value of an arbitrary 4-byte span of memory, via a chosen non-ctid input. While the calculation loses precision, substantial memory value recovery appears possible. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
