CVE-2026-13423: CWE-94 Improper Control of Generation of Code ('Code Injection') in Streamit
The Streamit WordPress theme through 4.5.0 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.
AI Analysis
Technical Summary
CVE-2026-13423 is a code injection vulnerability (CWE-94) in the Streamit WordPress theme through version 4.5.0. The theme exposes an unauthenticated AJAX endpoint that does not perform authorization or nonce checks, allowing attackers to supply arbitrary PHP function names and arguments. This can lead to unauthorized function execution, including creating administrator accounts, resulting in privilege escalation and remote code execution.
Potential Impact
Unauthenticated attackers can exploit this vulnerability to execute arbitrary PHP functions on the server, which may allow them to escalate privileges to administrator level and execute remote code. This compromises the confidentiality, integrity, and availability of the affected WordPress site.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the vulnerable AJAX endpoint if possible or disable the Streamit theme. Monitor vendor channels for updates and apply patches promptly once released.
