CVE-2026-5535 Details
Description
A security flaw has been discovered in FedML-AI FedML up to 0.8.9. This impacts an unknown function of the file FileUtils.java of the component MQTT Message Handler. Performing a manipulation of the argument dataSet results in path traversal. The attack is possible to be carried out remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
A path traversal vulnerability has been identified in the FedML-AI FedML Android client, affecting versions through 0.8.9. The issue arises in the MQTT message handling component, specifically within the FileUtils.java file. The vulnerability allows an attacker to manipulate the dataSet parameter in MQTT messages, leading to unauthorized access and enumeration of directories in the application's accessible filesystem. This exploitation is possible remotely, and a public proof-of-concept is available.
It is recommended to validate the dataSet input to prevent path traversal, enforce canonical path restrictions, and improve MQTT security by applying authentication and strict topic access controls.
