Custom Fonts – Host Your Fonts Locally is a WordPress plugin that allows users to host their custom fonts directly on their website. It is predominantly used by website developers and designers who want to enhance website aesthetics and performance by managing typography locally. The plugin is popular in design-focused projects due to its flexibility in font management. Using Custom Fonts – Host Your Fonts Locally, designers can create a consistent look across their website by ensuring fonts load directly from their server rather than external locations.

The vulnerability identified relates to version detection of the Custom Fonts – Host Your Fonts Locally plugin. This type of detection vulnerability allows for assessing whether the version in use is outdated or not. If a site is using an outdated version of a plugin, it might lack important security patches and improvements provided in newer releases. Such vulnerabilities highlight the importance of regularly updating plugins to mitigate potential risks. The primary concern is the outdated software usage that can lead to larger security issues if not addressed promptly. By identifying plugin versions, users can ensure their websites implement the best practices in security by utilizing the latest software versions.

Technical details of this vulnerability include detecting the version of the Custom Fonts – Host Your Fonts Locally plugin by parsing the readme.txt file. Through HTTP GET requests to specific paths, the scanner searches for patterns related to version declarations. The use of regex expressions facilitates the extraction of version strings, which are then compared to a known latest version. If the identified version is older than the latest known version, it signals that the plugin may be outdated. Crucial endpoints include paths specific to the WordPress plugin directory where such versioning files typically reside.

If exploited, the effects of using an outdated plugin version might include exposure to publicly known vulnerabilities previously addressed in newer releases. Such vulnerabilities could be used by attackers to compromise site data or functionality. Even if the vulnerability does not directly lead to an attack, it increases the likelihood of a successful exploit by adversaries familiar with older software flaws. The lack of updates makes systems vulnerable to exploits detailed in past security advisories for the plugin. Regular updates mitigate this risk by ensuring all known vulnerabilities have been patched.
