The vulnerability has been assigned a CVSS v3.1 Base Score of 6.1 (MEDIUM) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N (NVD).

The HTML injection vulnerability can result in the modification of web page content or the execution of malicious scripts, potentially leading to theft of sensitive information, malware distribution, phishing attacks, website defacement, or denial of service. This can significantly impact the reputation and security of the organization (ESec Forte).

The vulnerability requires proper input validation and sanitization of user input to prevent HTML injection attacks. Organizations using OpenCRX version 5.2.0 should implement these security measures or upgrade to a patched version when available (ESec Forte).
