What is CVE-2024-3996?

The Smart Post Show WordPress plugin prior to version 2.4.28 is susceptible to Stored Cross-Site Scripting due to insufficient sanitization and escaping of certain settings. This security flaw enables high privilege users, such as administrators, to execute malicious scripts, which could lead to unauthorized actions even when the unfiltered_html capability is restricted, like in multisite environments. Proper validation and sanitization measures need to be implemented to mitigate this risk.

Affected Version(s)

Smart Post Show 0 < 2.4.28

Exploit Proof of Concept (PoC)
