Summary

pgcollection is an open source extension to PostgreSQL. A type confusion issue in versions 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.

Risk Assessment

An authenticated database user could take over the PostgreSQL server and execute arbitrary code as the postgres account. This could lead to a full compromise of data confidentiality, integrity, and availability.

Recommendation

Immediately upgrade pgcollection to version 2.1.2 or later. Until patched, restrict privileges of users allowed to run SQL queries using this extension.
