| 제목 | Eyeo GmbH Adblock Plus 4.36.2 Privilege Escalation |
|---|
| 설명 | A missing origin validation in premium.preload.js allows any JavaScript
running in the context of accounts.adblockplus.org to forge a
payment_success postMessage event and activate the Premium subscription
without payment. The extension background (background.js) further fails
to bind the submitted userId to a verified payment session before
persisting it and initiating license_check. Tested on v4.36.2,
reproducible in ~30 seconds with a single line of JavaScript. |
