CVE-2021-43762Network attack vector

Unauthenticated content exposure via Unicode selector bypass

Published Jan 13, 2022 · Updated Sep 17, 2024

Improper input validation in Adobe Experience Manager 6.5.10.0 and earlier allows remote attackers to bypass dispatcher controls. Dispatcher rules match Latin numeric selectors but fail to recognize equivalent non-Latin digits, while AEM interprets them as selectors and invokes renderers. An unauthenticated crafted request can therefore reach restricted JSON-rendered content; Adobe also identifies its Cloud Service offering as affected.
