 "title": "Link Whisper Free <= 0.9.7 - Authenticated (Subscriber+) Missing Authorization to Broken Link Scan, Link Ignore List and Plugin Option Updates",
 "description": "The Link Whisper Free plugin for WordPress is vulnerable to unauthorized modification of data because several AJAX actions (wpil_error_process, wpil_add_link_to_ignore, wpil_clear_process_tracker, wpil_has_run_wizard, wpil_wizard_set_completion_flag and wpil_update_expanded_details_toggle) are missing capability checks in all versions up to, and including, 0.9.7. This makes it possible for authenticated attackers with Subscriber-level access and above to start broken link scans, add posts to the plugin's link ignore list, and change the plugin's wizard and display state.",
