CVE-2026-126119 Streamit Plugin < 1.3.10 - Unauthenticated Remote Code Execution via Arbitrary Function Call

9.8 criticalEPSS 0.2%

Critical (9.8) in unknown streamit. EPSS 0.2% estimated probability of exploitation activity in the next 30 days.

On this page
The Streamit WordPress plugin before 1.3.10 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.

If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-126119 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.
