Is Enable Media Replace safe? Known vulnerabilities and latest version

Subscriber PHP Object Injection in Enable Media Replace <= 4.2.2 versions.

The Enable Media Replace WordPress plugin before 4.2.3 does not restrict the classes allowed when deserializing stored metadata during its media replace-and-update-links routine, allowing unauthenticated users to inject a PHP object that is instantiated when a user with upload access performs a routine media replacement, resulting in PHP Object Injection and local file inclusion of existing PHP/HTML files, which can be escalated to remote code execution where an attacker-influenced PHP or HTML file is present on the server. This is a regression of CVE-2023-4643, which was fixed in 4.1.3 and reintroduced in 4.1.4.

The Enable Media Replace plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.2.2. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with author-level access and above, to modify the post_content of any published post referencing the replaced media — including Administrator-owned posts — making changes immediately visible to unauthenticated visitors. The doReplaceQuery() method performs a database-wide search-and-replace across all posts containing the old media URL without any per-post capability check, meaning a single Author-triggered request can silently overwrite a large number of posts that WordPress's standard admin UI and REST API would otherwise forbid that user from editing.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in ShortPixel Enable Media Replace allows Stored XSS. This issue affects Enable Media Replace: from n/a through 4.2.1.

The Enable Media Replace plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘location_dir’ parameter in all versions up to, and including, 4.1.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Enable Media Replace plugin for WordPress is vulnerable to unauthorized modification of data due to an improper capability check on the 'RemoveBackGroundViewController::load' function in all versions up to, and including, 4.1.7. This makes it possible for authenticated attackers, with Author-level access and above, to replace any attachment with a removed background attachment.

The Enable Media Replace plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's file_modified shortcode in all versions up to, and including, 4.1.6 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in ShortPixel Enable Media Replace enable-media-replace allows Reflected XSS.This issue affects Enable Media Replace: from n/a through <= 4.1.5.

The Enable Media Replace plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the SHORTPIXEL_DEBUG parameter in all versions up to, and including, 4.1.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Exploiting this vulnerability requires the attacker to know the ID of an attachment uploaded by the user they are attacking.

The Enable Media Replace WordPress plugin before 4.1.3 unserializes user input via the Remove Background feature, which could allow Author+ users to perform PHP Object Injection when a suitable gadget is present on the blog

The Enable Media Replace WordPress plugin before 4.0.2 does not prevent authors from uploading arbitrary files to the site, which may allow them to upload PHP shells on affected sites.

The Enable Media Replace WordPress plugin before 4.0.0 does not ensure that renamed files are moved to the Upload folder, which could allow high privilege users such as admin to move them outside to the web root directory via a path traversal attack for example
