Description
WordPress Plugin A/B Test is prone to a directory traversal vulnerability because it fails to sufficiently sanitize user-supplied input. Exploiting this issue can allow an attacker to obtain sensitive information that could aid in further attacks. WordPress Plugin A/B Test version 1.0.6 is vulnerable; other versions may also be affected.
Remediation
Edit the source code to ensure that input is properly verified or disable the plugin until a fix is available
