CVE-2026-96883: Type confusion in AWS pgcollection allows remote code execution
Description
pgcollection is an open source extension to PostgreSQL. A type confusion issue in AWS pgcollection 2.0.0 through 2.1.1 might allow an authenticated remote user to execute arbitrary code as the postgres operating system user via crafted SQL statements that rely on mismatched type metadata in collection value retrieval and array conversion functions. To remediate this issue, users should upgrade to version 2.1.2 or later.
