CWE-94: Improper Control of Generation of Code ('Code Injection')
Reaching this weakness in xSmart - App Landing Page WordPress Theme in Tech Presentation, Promo Marketing & Advertising Agency <= 1.2.9.4 takes an account at Subscriber level or above. Code injection means input from a request reaches a language construct that evaluates code, so the attacker's text is executed rather than treated as data.
The injected code runs with the web server's privileges, giving the attacker the same access to the database and filesystem as WordPress itself. No fixed build of this theme is recorded for xSmart - App Landing Page WordPress Theme in Tech Presentation, Promo Marketing & Advertising Agency yet, so installs running <= 1.2.9.4 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
