High (8.8). EPSS 0.6% estimated probability of exploitation activity in the next 30 days.
On this page
Type confusion in PostgreSQL statistics import allows a table maintainer to execute arbitrary code as the operating system user running the database, via nested SET DATA TYPE during conversion of values to import. Within major version 18, minor versions before PostgreSQL 18.7 are affected. Versions before PostgreSQL 18 are unaffected.

Red Hat
Red Hat rates this Important.
This vulnerability is evaluated as Important because authenticated users with table modification rights could execute arbitrary commands under the privileges of the database service account. However, Red Hat Enterprise Linux environments deploy PostgreSQL streams earlier than version 18, which do not contain the vulnerable statistics import functionality. Consequently, default installations on supported Red Hat platforms are not impacted by this flaw.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
