Name of the Vulnerable Software and Affected Versions Easy Digital Downloads – Simple eCommerce for Selling Digital Files plugin for WordPress versions up to, and including 3.3.3

Description The issue concerns deserialization of untrusted input via the upload[file] parameter. This allows authenticated administrative users to call files using a PHAR wrapper, which can deserialize and call arbitrary PHP Objects. These objects can be used to perform malicious actions if a POP chain is also present.

Recommendations For versions up to, and including 3.3.3, update to a version higher than 3.3.3 to resolve the issue. As a temporary workaround, consider restricting access to the upload[file] parameter to minimize the risk of exploitation.
