Unauthenticated script execution in victim browsers
Published Jul 13, 2026 · Updated Jul 13, 2026
Reflected XSS in RT-Themes RT-Theme 18 Extensions 2.5 and earlier allows remote attackers to execute script in a victim's browser. Neither the CNA record nor Patchstack identifies the vulnerable parameter, request handler, or output operation that reflects untrusted input. Exploitation is unauthenticated but requires a victim to follow a crafted link or otherwise submit the attacker-controlled request, after which the script runs in that site's browser context.
