Source description

As published by the source; long descriptions are shortened.

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.

# Patch Next advisory brief: GHSA-wchh-9x6h-7f6p

Advisory: olm dependency deprecation: CVE-2022-39255 and CVE-2024-45193
IDs: GHSA-wchh-9x6h-7f6p
Record: https://patchnext.com/advisories/ghsa-wchh-9x6h-7f6p (revision 1, source checked 26 Oct 2026, 13:50 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI matrix-commander: affected <= 8.0.6

## Suggested inspection (read-only)
- `python -m pip show matrix-commander`: prints the installed version. Run with the environment that serves production active.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on matrix-commander.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-wchh-9x6h-7f6p (GitHub-reviewed advisory GHSA-wchh-9x6h-7f6p lists affected ranges: PyPI matrix-commander >=0 <=8.0.6)

Commands are suggestions: review each one before running it.
