The rafasashi SVG Captcha library versions up to 1.0.11 contain a reflected Cross-site Scripting (XSS) vulnerability due to improper neutralization of input during web page generation. This flaw allows attackers to inject malicious scripts that execute in the context of the victim's browser, potentially leading to information disclosure, manipulation of data, or disruption of service. The CVSS 3.1 base score is 7.1, indicating a high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability. No patch or vendor advisory is currently provided.

Successful exploitation of this vulnerability can lead to reflected XSS attacks, which may allow attackers to execute arbitrary scripts in the context of users' browsers. This can result in partial loss of confidentiality, integrity, and availability of affected systems or data. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
