CVE-2025-9194

Constructor <= 1.6.5 - Missing Authorization to Authenticated (Subscriber+) Theme Clean

Published Oct 3, 2025 CVSS 3.1 · 4.3 Medium EPSS < 1% KEV · Not listed

Description

The Constructor theme for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the clean() function in all versions up to, and including, 1.6.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to trigger a theme clean.

Analysis

Technical impact

A missing capability check in the clean() function of the Constructor WordPress theme permits authenticated users with Subscriber-level access or higher to trigger a theme clean operation. This operation can remove or reset theme files and potentially alter or delete site content, thereby compromising the integrity of the website.

Affected Systems

The vulnerability affects all installations of the Constructor theme from the vendor "antonshevchuk:Constructor" for versions up to and including 1.6.5.

Risk and Exploitability

The CVSS score of 4.3 indicates moderate severity, while the EPSS score of less than 1% shows a very low probability of exploitation currently. The issue is not listed in CISA’s KEV catalog. Attackers must be authenticated with Subscriber or higher privileges to exploit the flaw, making the risk contingent on the presence of such accounts.

Affected Products

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