Summary

TripleLift's ad rendering script (video-bundle.js) contains a DOM-based cross-site scripting vulnerability that allows unauthenticated attackers to execute arbitrary JavaScript in a publisher's domain by sending crafted postMessage payloads without origin validation. Attackers can cause a victim to visit an attacker-controlled page that sends malicious postMessage events to a publisher page running the ad script, enabling session hijacking and unauthorized DOM manipulation.
