Record description
Lukas Weichselbaum identifies himself in a public LinkedIn post as part of the team that built PageBreak, an internal Google security agent. He describes how external, engineer-written validators verify running-app behavior and recounts three reported findings: a signature-oracle bypass in an admin.google.com flow, JavaScript cache poisoning at apis.google.com, and universal XSS in the Tag Assistant extension. These are his team account of findings, not independent reproductions or proof that the vulnerabilities were exploited outside authorized testing.
