CVE-2026-57421 describes a reflected cross-site scripting (XSS) vulnerability in CRM Perks Forms (versions up to 1.1.7). The issue is caused by improper neutralization of input during web page generation, which allows attackers to inject malicious scripts that execute in the victim's browser. The CVSS 3.1 score is 7.1 (high), with network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability rated as low to low to low respectively. No vendor advisory or patch information is provided, and no known exploits in the wild have been reported.

Successful exploitation of this vulnerability can allow an attacker to execute arbitrary scripts in the context of a user's browser session, potentially leading to partial disclosure of sensitive information, modification of data, or disruption of service. The CVSS vector indicates that the attack can be performed remotely without privileges but requires user interaction. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with untrusted input and consider implementing web application firewalls or input validation as temporary mitigations.
