CVE-2026-73360Network attack vector

Script execution via undisclosed XSS flaw

Published Aug 18, 2026 · Updated Aug 18, 2026

Cross-site scripting in Premio Chaty Pro through 3.5.8 allows remote attackers to run script in a visitor browser via unspecified vectors. Patchstack has not disclosed the vulnerable endpoint, parameter, or code path, so the public record does not show which input reaches unescaped HTML or script output. Exploitation is unauthenticated but requires a user to load the affected page in the site's origin, limiting the demonstrated consequence to browser-side script execution with low confidentiality, integrity, and availability impact.
