GHSA-wchh-9x6h-7f6p
GHSA-wchh-9x6h-7f6p is a security vulnerability in matrix-commander. O3 Security confirms whether GHSA-wchh-9x6h-7f6p is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
Problem
Multiple vulnerabilities were disclosed in 2024 affecting libolm (Olm): AES timing / side‑channel, Ed25519 signature malleability, and timing leaks in base64 decoding; several CVEs were assigned. Patches and mitigations were published; maintainers recommend upgrading to fixed versions. In addition, a 2022 “Olm/Megolm protocol confusion” advisory affecting some SDKs was critical and required client-side fixes. Use patched versions of libolm and up-to-date Matrix SDKs; avoid unpatched clients/servers.
Olm is a dependency of matrix-commander (Python version, not Rust version).
WARNING:
Due to cryptographic olm dependency deprecation, this program is cryptographically unsafe to use until https://github.com/matrix-nio/matrix-nio/pull/555 is merged. Good news: https://github.com/8go/matrix-commander-rs is a Rust alternative not having this issue.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for matrix-commander. 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.
Remediation status
No patched version of matrix-commander has shipped for GHSA-wchh-9x6h-7f6p yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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.
How O3 protects you
O3 pinpoints whether GHSA-wchh-9x6h-7f6p 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-wchh-9x6h-7f6p. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-wchh-9x6h-7f6p in your dependencies?
O3 detects GHSA-wchh-9x6h-7f6p across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
