CVE-2025-59047 – matrix-sdk-base has panic in the `RoomMember::normalized_power_level()` method

CVE ID : CVE-2025-59047

Published : Sept. 11, 2025, 6:15 p.m. | 27 minutes ago

Description : matrix-sdk-base is the base component to build a Matrix client library. 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`. The issue is fixed in matrix-sdk-base 0.14.1. The affected method isn’t used internally, so avoiding calling `RoomMember::normalized_power_level()` prevents the panic.

Severity: 2.7 | LOW
