Deeper analysis

The Page View Count WordPress plugin before version 2.4.15 is affected by an SQL injection vulnerability tracked as CVE-2022-0434. The plugin fails to sanitize or escape the post_ids parameter before incorporating it into a SQL statement exposed through a REST endpoint that is reachable by both unauthenticated and authenticated users. The issue is classified under CWE-89 and carries a CVSS 3.1 score of 9.8 reflecting network-accessible attack vectors with no required authentication or user interaction.

Unauthenticated attackers can supply crafted input to the vulnerable REST endpoint and execute arbitrary SQL queries against the underlying database. Successful exploitation can result in full compromise of confidentiality, integrity, and availability of the WordPress site data, consistent with the CVSS vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H.

The referenced WPScan advisory at https://wpscan.com/vulnerability/be895016-7365-4ce4-a54f-f36d0ef2d6f1 documents the flaw and the affected plugin versions. The current EPSS score of 0.8792, with a recorded peak of 0.9056, indicates sustained exploitation interest following disclosure.
