CVE-2023-48275: 
WordPress vulnerability analysis and mitigation

Multiple WordPress plugins by Trustindex.io were found to contain an arbitrary file upload vulnerability, identified as CVE-2023-48275. The vulnerability was discovered on November 22, 2023, affecting various versions of multiple review widget plugins. The issue impacts numerous plugins including wp-reviews-plugin-for-google, customer-reviews-collector-for-woocommerce, and multiple other review widgets for platforms such as Airbnb, Amazon, and Yelp (WPScan).

The vulnerability stems from missing file type validation in the ~/tabs/featurerequest.php file. This security flaw allows authenticated attackers with editor-level access or higher to upload arbitrary files to the affected site's server. The vulnerability carries a CVSS score of 8.0, indicating a medium to high severity. The issue is particularly concerning as it may enable remote code execution in specific scenarios where the server is overloaded and the unlink() function is not triggered immediately following moveuploadedfile() ([Patchstack](https://patchstack.com/database/vulnerability/wp-reviews-plugin-for-google/wordpress-widgets-for-google-reviews-plugin-11-0-2-arbitrary-file-upload-vulnerability?s_id=cve)).

The vulnerability could allow malicious actors to upload any type of file to the affected website, including potential backdoors that could be executed to gain further access to the website's systems. This could lead to remote code execution under specific server conditions (Patchstack).

All affected plugins have been patched in version 11.1, with the customer-reviews-collector-for-woocommerce fixed in version 4.0. Website administrators are advised to update to these versions or later immediately to resolve the vulnerability. Virtual patching solutions are available through security providers to mitigate the issue until updates can be applied (WPScan, Patchstack).
