WordPress · Ninja Forms Contact Form · CVE-2022-2903
**Name of the Vulnerable Software and Affected Versions**
Ninja Forms Contact Form WordPress plugin versions prior to 3.6.13
**Description**
The issue arises from the unserialization of the content of an imported file, potentially leading to PHP object injections when an admin imports a malicious file and a suitable gadget chain is present on the blog. This could occur intentionally or unintentionally.
**Recommendations**
For versions prior to 3.6.13, update to version 3.6.13 or later to resolve the issue. As a temporary workaround, consider restricting file imports to trusted sources and avoiding the import of files from unverified locations.
