Reflected XSS in AndroidBubbles Keep Backup Daily 2.0.2 and earlier allows remote attackers to execute scripts via the t parameter. The plugin reflects the t request parameter into an HTML response without sufficient sanitization or output escaping. No authentication is required, but a victim must follow a crafted link; execution occurs in that victim’s browser context, enabling page-content access or modification.
