CVE-2023-5817

18
FAUCET Score

CVE-2023-5817 describes a Stored Cross-Site Scripting (XSS) vulnerability in the Neon text plugin for WordPress, affecting all versions up to and including 1.1. This flaw stems from insufficient input sanitization of the 'color' attribute within the neontext_box shortcode. Authenticated attackers with contributor-level permissions or higher can inject malicious web scripts into pages, which then execute when a user views the compromised page. The vulnerability has a CVSS score of 5.4 (MEDIUM), indicating a low attack complexity and requiring user interaction, with potential impacts on confidentiality and integrity. While it allows for arbitrary script execution, it does not lead to a complete compromise of the system. Currently, there is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage for this CVE are minimal, suggesting a low level of public awareness or concern.
