At a glance
CVE-2023-28693 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Advanced Youtube Channel Pagination WordPress plugin, affecting versions <= 1.0. It carries a CVSS score of 5.5 (reachable over the network; low attack complexity). No fixed release has been reported yet; treat installations running this software as exposed. Disclosed April 2023, reported by qilin_99.
Vulnerability Overview
The Advanced Youtube Channel Pagination plugin for WordPress is vulnerable to Cross-Site Request Forgery due to a missing nonce check on the ‘youtube_channel_pagination_init’ parameter in versions up to, and including, 1.0. Combined with insufficient input sanitization and output escaping, this makes it possible for unauthenticated attackers to modify plugin settings and inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Advanced Youtube Channel Pagination <= 1.0 carries this weakness at youtube_channel_pagination_init, and reaching it takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. No fixed build of this plugin is recorded for Advanced Youtube Channel Pagination yet, so installs running <= 1.0 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
The attempt arrives as an ordinary request to Advanced Youtube Channel Pagination: WordSec's web application firewall inspects request payloads before WordPress loads them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
