CVE-2023-4779 describes a Stored Cross-Site Scripting (XSS) vulnerability in the User Submitted Posts plugin for WordPress, affecting versions up to and including 20230811. This flaw stems from insufficient input sanitization and output escaping within the [usp_gallery] shortcode, specifically with user-supplied attributes like 'before'. Authenticated attackers with contributor-level permissions or higher can inject malicious web scripts into pages. The vulnerability carries a CVSS score of 5.4 (Medium), indicating a network-based attack with low complexity, requiring user interaction, and resulting in low impact to confidentiality and integrity. While the attack requires an authenticated user, the potential for script execution on user access makes it a concern. Currently, there is no evidence of active exploitation, nor are there publicly available exploit modules in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage for this CVE are minimal, suggesting it has not garnered significant attention.
