A vulnerability was found in TeamNewPipe NewPipe App up to 0.26.1 on Android. It has been declared as problematic. Affected by this vulnerability is an unknown function. The manipulation with an unknown input leads to a deserialization vulnerability. The CWE definition for the vulnerability is CWE-502. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

NewPipe is an Android app for video streaming written in Java. It supports exporting and importing backups, as a way to let users move their data to a new device effortlessly. However, in versions 0.13.4 through 0.26.1, importing a backup file from an untrusted source could have resulted in Arbitrary Code Execution. This is because backups are serialized/deserialized using Java's Object Serialization Stream Protocol, which can allow constructing any class in the app, unless properly restricted. To exploit this vulnerability, an attacker would need to build a backup file containing the exploit, and then persuade a user into importing it. During the import process, the malicious code would be executed, possibly crashing the app, stealing user data from the NewPipe app, performing nasty actions through Android APIs, and attempting Android JVM/Sandbox escapes through vulnerabilities in the Android OS. The attack can take place only if the user imports a malicious backup file, so an attacker would need to trick a user into importing a backup file from a source they can control. The implementation details of the malicious backup file can be independent of the attacked user or the device they are being run on, and do not require additional privileges. All NewPipe versions from 0.13.4 to 0.26.1 are vulnerable. NewPipe version 0.27.0 fixes the issue by doing the following: Restrict the classes that can be deserialized when calling Java's Object Serialization Stream Protocol, by adding a whitelist with only innocuous data-only classes that can't lead to Arbitrary Code Execution; deprecate backups serialized with Java's Object Serialization Stream Protocol; use JSON serialization for all newly created backups (but still include an alternative file serialized with Java's Object Serialization Stream Protocol in the backup zip for backwards compatibility); show a warning to the user when attempting to import a backup where the only available serialization mode is Java's Object Serialization Stream Protocol (note that in the future this serialization mode will be removed completely).

The advisory is shared at github.com. This vulnerability is known as CVE-2024-32876 since 04/19/2024. The exploitation appears to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available.

Upgrading to version 0.27.0 eliminates this vulnerability. The upgrade is hosted for download at github.com. Applying the patch a69bbab73220f36e53c801cf7e9ea3627bb017eb is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
