4) Security features bypass
EUVDB-ID: #VU76042
Risk: Low
CVSSv3.1: 2 [CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-2455
CWE-ID:
CWE-254 - Security Features
Exploit availability: No
DescriptionThe 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.

6) SQL injection
EUVDB-ID: #VU79454
Risk: Medium
CVSSv3.1: 6.4 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-39417
CWE-ID:
CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary SQL queries in database.
