CVE-2023-27890 describes a Cross-Site Scripting (XSS) vulnerability in the Export User plugin (versions up to 2.0) for MyBB, specifically exploitable when an administrator generates DSGVO data. This medium-severity vulnerability (CVSS 5.4) allows an attacker to inject malicious scripts via the Custom User Title, Location, or Bio fields, requiring low privileges and user interaction. While the potential impact is limited to low confidentiality and integrity, it's crucial to note that this vulnerability affects products no longer supported by their maintainer. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
