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.
CVE-2025-59047
This low-severity CVE scores 2.7 under NVD CVSS v3. EPSS exploit probability: 0.4%, top 70% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
