Status: published. Published: 2026-10-28. Updated: 2026-11-03.

Topluyo is a social networking platform.

An attacker who controls a target URL can execute arbitrary operating system commands with the privileges of the user running the application upon opening the link. Version 2026.9.2410 patches the issue.
