CVE-2021-40527Network attack vector

Developer-file disclosure via embedded AWS credentials

Published Oct 25, 2021 · Updated Aug 4, 2024

Information disclosure in the com.onepeloton.erlich Android app 1.7.22 and earlier allows remote attackers to read S3 developer files. The application embeds AWS credentials in plaintext, allowing extracted keys to authenticate to the developer bucket. No application login or user interaction is required; possession of an affected app package exposes the credentials and permits remote access to developer data.
