CVE-2026-13423
Streamit < 4.5.2 - Unauthenticated Remote Code Execution via Arbitrary Function Call
The Streamit WordPress theme before 4.5.2 does not perform any authorization or nonce verification on one of its unauthenticated AJAX routes, which invokes an attacker-supplied PHP function with an attacker-supplied argument array, allowing unauthenticated attackers to call arbitrary functions (for example to create an administrator account), leading to privilege escalation and remote code execution.
