3DescriptionCVE.org
The JS Archive List plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 6.1.7 via the 'included' shortcode attribute. This is due to the deserialization of untrusted input supplied via the 'included' parameter of the plugin's shortcode. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
AnalysisAI
PHP object injection in the JS Archive List WordPress plugin (versions up to 6.1.7) allows authenticated contributors and above to deserialize untrusted data through the shortcode 'included' parameter. While no direct exploitation path exists in the plugin itself, attackers could leverage gadget chains from other installed plugins or themes to achieve arbitrary file deletion, information disclosure, or remote code execution. A patch is not currently available.
