Prebid.js 11.36.0 released with security fixes
Prebid.js released version 11.36.0 on September 28, 2026. This maintenance release includes two core PRs: sanitizing untrusted ORTB responses to enhance security, and resetting GPT targeting on bid win. Several bidder adapters (Pubstack, Ogury, msft, AdSpirit, MCodeMedia, SSP Geniee) received fixes and updates. A notable change is the refactoring of bidder COPPA config access across various adapters. The update also includes documentation updates for IntentIq ID and a name change for MCodeMedia. These changes aim to improve stability, security, and compliance for publishers using Prebid.js.
Prebid.js is a widely used open-source header bidding wrapper. Security and stability fixes are important for the AdTech ecosystem, but this is a routine maintenance release without major feature changes.
