Filter Gallery < 1.1.5 - Subscriber+ Arbitrary Post Overwrite and Plugin Option Deletion via Fail-Open Nonce Check
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
The Filter Gallery WordPress plugin before 1.1.5 does not verify the nonce on several of its AJAX handlers when the nonce field is omitted, and applies no capability check, allowing low-privileged users to overwrite the content of arbitrary posts and delete the Filter Gallery WordPress plugin before 1.1.5's stored gallery options.
