CVE-2025-2109

WP Compress <= 6.30.15 - Unauthenticated Server-Side Request Forgery via init Function

Published Mar 25, 2025 CVSS 3.1 · 5.8 Medium EPSS < 1% KEV · Not listed

Description

The WP Compress – Instant Performance & Speed Optimization plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 6.30.15 via the init() function. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query information from internal services.

Analysis

Technical impact

The WP Compress – Instant Performance & Speed Optimization plugin contains a Server‑Side Request Forgery flaw in its init() function. This flaw allows an unauthenticated remote user to cause the plugin to send arbitrary HTTP or HTTPS requests from the host on which the WordPress site is running. As a result an attacker can probe internal network services, retrieve configuration data, or access resources that are otherwise unreachable from the Internet.

Affected Systems

Any installation of the WP Compress plugin version 6.30.15 or older is affected. The vulnerability has been identified in the plugin released by aresit for WordPress and applies to all WordPress sites that have not updated past that version.

Risk and Exploitability

The CVSS score of 5.8 indicates moderate severity, and the EPSS score of less than 1% points to a low likelihood of exploitation. The vulnerability is not catalogued in CISA’s KEV list, suggesting no widespread exploitation has been reported. Attackers would need network access to the WordPress server and no authentication; once accessed, they could craft SSRF requests to internal or privileged endpoints to gather sensitive information.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
