Description OSIDB Bzimport 2026-11-12 14:34:13 UTC 
Exposure of sensitive information in PostgreSQL security_barrier processing allows a database user to infer values hidden by a security_barrier view, via applying a leaky function to a CASE test value or internal parameter that indirectly represents a protected column.  Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
