It carries a CVSS score of 8.0 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account.

Vulnerability Overview

lib\modules\contributors\contributor_list_table.php in the Podlove Podcast Publisher plugin 2.5.3 and earlier for WordPress has SQL injection in the orderby parameter to wp-admin/admin.php, exploitable through 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. 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 < 2.6.0 takes any authenticated account. 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 2.6.0: builds < 2.6.0 are affected, anything from 2.6.0 onward is not.

Remediation

Update to version 2.6.0, 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 2.6.0 closes this, and updating the plugin is the step that ends it.
