Reflected XSS via unescaped AJAX post identifier
Published Mar 14, 2022 · Updated Aug 2, 2024
Reflected XSS in Ohio Web Technologies WP Voting Contest Lite before 3.0 allows remote attackers to execute script via an AJAX request. The wpvc_social_share_icons action returns the post_id parameter without sanitizing or escaping attacker-controlled markup. The action accepts unauthenticated requests, but exploitation requires a victim to submit the crafted request and renders script in that victim's browser context.
