CVE-2024-1056

CVSS v3.1

6.4

Medium

VectorAV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N
Name of the Vulnerable Software and Affected Versions FunnelKit Funnel Builder Pro plugin for WordPress versions up to, and including, 3.4.5
Description The issue is related to Stored Cross-Site Scripting, where the allow iframe tag in post function uses the wp kses allowed html filter to globally allow script and iframe tags in posts. This allows authenticated attackers with contributor access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Recommendations For versions up to, and including, 3.4.5, consider disabling the allow iframe tag in post function as a temporary workaround until a patch is available. Restrict access to the wp kses allowed html filter to minimize the risk of exploitation. Avoid using the wp kses allowed html filter to allow script and iframe tags in posts until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
