CVE-2026-15452Network attack vector

Reflected XSS via unescaped request URI

Published Aug 5, 2026 · Updated Aug 5, 2026

Reflected XSS in Smash Balloon Social Photo Feed 6.11.3 and earlier allows remote attackers to execute script through a crafted request URI. The SBI_Callout.php callout renderer uses the REQUEST_URI query string in generated output without sufficient sanitization and escaping. Execution requires an unauthenticated attacker to persuade a user to open a crafted link, after which the injected script runs in that user's browser.
