CVE-2023-25445

Overview

The HappyFiles Pro WordPress plugin contains a missing authorization vulnerability, classified as a broken access control issue. The flaw exists in versions through 1.8.1, where the plugin fails to perform proper permission checks on certain functions. This allows unprivileged users to execute actions that should require higher privileges, such as administrative capabilities [1].

Attack

Vector and Requirements

No authentication bypass is required beyond having an account on the target WordPress site. An attacker who can access the site (e.g., as a subscriber or other low-privileged role) can exploit the missing authorization checks to invoke functions intended for administrators or other higher-privileged roles. The vulnerability does not require any special network position or additional user interaction [1].

Potential

Impact

Successful exploitation enables an attacker to perform unauthorized actions, potentially including modifying plugin settings, accessing protected data, or other operations that affect the site's functionality. The CVSS score of 5.4 (Medium) reflects the Plugin has been flagged by vulnerability tracking as moderately dangerous and likely to be used in mass-exploit campaigns against thousands of websites [1].

Mitigation and

Remediation

The vendor has released a patched version 1.8.2. Users are strongly advised to update immediately. If an immediate update is not possible, users should seek assistance from their hosting provider or web developer. Security platforms like Patchstack offer mitigation rules that can block exploitation attempts until the update is applied [1].
