Unsanitized postratings_image Parameter in WP-PostRatings Plugin

CVE-2021-25117 · MEDIUM Severity

CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N

The WP-PostRatings WordPress plugin before 1.86.1 does not sanitise the postratings_image parameter from its options page (wp-admin/admin.php?page=wp-postratings/postratings-options.php). Even though the page is only accessible to administrators, and protected against CSRF attacks, the issue is still exploitable when the unfiltered_html capability is disabled.
