The yonifre Lenix scss compiler (versions up to 1.2) contains a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This vulnerability could allow an attacker with high privileges and requiring user interaction to inject malicious scripts, potentially impacting confidentiality, integrity, and availability to a limited extent. The CVSS 3.1 vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, and a scope change with low impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker with high privileges to execute stored malicious scripts in the context of the web pages generated by the Lenix scss compiler. This may lead to limited confidentiality, integrity, and availability impacts as indicated by the CVSS score. No known exploits in the wild have been reported, so the practical impact currently appears limited.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor vendor communications for updates. Until a fix is available, limit exposure by restricting high-privilege access and exercising caution with user inputs that may be processed by the compiler.
