Vulnerability Overview

The podlove-podcasting-plugin-for-wordpress plugin before 2.3.16 for WordPress has SQL injection via the insert_id parameter exploitable via CSRF.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Reaching this weakness in Podlove Podcast Publisher < 2.3.16 takes a caller who can reach the endpoint. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.

A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For Podlove Podcast Publisher the fix is 2.3.16: builds < 2.3.16 are affected, anything from 2.3.16 onward is not.

Remediation

Update to version 2.3.16, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Podlove Podcast Publisher: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Podlove Podcast Publisher 2.3.16 closes this, and updating the plugin is the step that ends it.
