2) Security features bypass

EUVDB-ID: #VU76042

Risk: Low

CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-2455

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.
