CVE-2026-15359: Unknown Templately

Medium severity, CVSS 6.5. EPSS: 0.3% chance of exploitation in the next 30 days.

The Templately WordPress plugin before 3.7.1 does not have an authorisation check on one of its request handlers, allowing unauthenticated attackers to overwrite the administrator's stored cloud service connection with an account under their control, disconnecting the legitimate administrator and redirecting the site's cloud template library to attacker-controlled content.
