This vulnerability (CVE-2026-65447) is an unauthenticated Cross-Site Scripting (XSS) flaw in Contest Gallery versions up to 30.0.6. It arises from improper neutralization of input during web page generation (CWE-79), allowing attackers to inject malicious scripts that can affect confidentiality, integrity, and availability. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and a scope change with low impact on confidentiality, integrity, and availability. No patch or official remediation level is currently documented.

Successful exploitation could allow remote attackers to execute arbitrary scripts in the context of the affected web application without authentication. This may lead to partial compromise of confidentiality, integrity, and availability of the affected system or user data. The scope is changed, indicating that the vulnerability affects resources beyond the initially vulnerable component.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or workaround is currently documented, users should monitor vendor communications for updates. Until a patch is available, consider applying any recommended temporary mitigations from the vendor if provided.
