Description

This security bulletin contains information about 1 vulnerability.


1) Security features bypass (CVE-ID: CVE-2023-2455)

The vulnerability allows a remote user to bypass implemented security restrictions.

The vulnerability exists due to incomplete fix for #VU40402 (CVE-2016-2193) that did not anticipate a scenario involving function inlining. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications.

This affects only databases that have used CREATE POLICY to define a row security policy.
