How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-59047, inspect your project dependencies for matrix-sdk-base:

inspect dependencies for matrix-sdk-base

Analyze the terminal output to locate any version of matrix-sdk-base in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.14.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-682: Incorrect Calculation, where the product performs a calculation that generates incorrect or unintended results that are later used in security-critical decisions or resource management. In matrix-sdk-base, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In matrix-sdk-base before 0.14.1, calling the `RoomMember::normalized_power_level()` method can cause a panic if a room member has a power level of `Int::Min`. ### Patches The issue is fixed in matrix-sdk-base 0.14.1. ### Workarounds The affected method isn’t used internally, so avoiding calling `RoomMember::normalized_power_level()` prevents the panic.
