CVSS v3.1
7.2
High
| Vector | AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
WordPress Importer plugin versions up to, and including, 0.8.3
Description
The issue is related to PHP Object Injection via deserialization of untrusted input in the
maybe unserialize function. This allows authenticated attackers with Administrator-level access and above to inject a PHP Object. However, the vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code, depending on the POP chain present.Recommendations
For WordPress Importer plugin versions up to, and including, 0.8.3, update to a version above 0.8.3 to resolve the issue. As a temporary workaround, consider disabling the
maybe unserialize function until a patch is available. Restrict access to the plugin to minimize the risk of exploitation. Avoid using untrusted input in the deserialization process until the issue is resolved.Fix
