Type confusion from incomplete PostgreSQL type-cache invalidation allows an object creator to execute arbitrary code as the operating system user running the database, via a composite type change while its cache entry is being populated. Within major version 18, minor versions before PostgreSQL 18.7 are affected. Versions before PostgreSQL 18 are unaffected.
