GHSA-qhj8-q5r6-8q6j

Fix: matrix-org/matrix-rust-sdk#5635

GHSA-qhj8-q5r6-8q6j is a CWE-682 vulnerability in matrix-sdk-base. O3 Security confirms whether GHSA-qhj8-q5r6-8q6j is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Real-World Exposure

1 pkg affected
🦀matrix-sdk-base

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.

Description

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.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for matrix-sdk-base. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update matrix-sdk-base to 0.14.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qhj8-q5r6-8q6j is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-qhj8-q5r6-8q6j is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-qhj8-q5r6-8q6j. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

Frequently Asked Questions

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.
