The yaycommerce Brand product versions up to 1.1.6 suffer from a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows attackers with at least low privileges and user interaction to inject malicious scripts that execute in the context of other users, potentially leading to partial compromise of confidentiality, integrity, and availability. The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, and scope change with low impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can result in stored XSS attacks, which may allow attackers to execute arbitrary scripts in the context of other users. This can lead to partial disclosure of information, modification of data, and disruption of service. The CVSS score of 6.5 reflects a medium impact on confidentiality, integrity, and availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should apply standard XSS mitigations such as input validation and output encoding where possible. Monitor vendor communications for updates regarding patches or official mitigations.
