Description OSIDB Bzimport 2026-11-12 14:31:25 UTC 
Type confusion in PostgreSQL composite-value field assignment allows an object creator to execute arbitrary code as the operating system user running the database, via changing a composite type between deforming and reforming a value.  Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
