CVE-2026-15298
No known patch is available for this vulnerability.
The affected plugin has not been updated on WordPress.org since before this CVE was disclosed; the latest installable version is still vulnerable. If you have the affected software installed, you should uninstall or replace it rather than wait for an update.
Description
The TelSender plugin for WordPress is vulnerable to DOM-Based Cross-Site Scripting in all versions up to, and including, 1.14.14. This is due to insufficient input sanitization when processing Telegram API responses containing attacker-controlled chat titles. This makes it possible for unauthenticated attackers to inject malicious scripts via Telegram chat titles that execute when an administrator opens the TelSender settings page and clicks the "Tested" button.
