An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-wchh-9x6h-7f6p in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- matrix-commander (PyPI): affected all versions up to 8.0.6; no fix listed\n- matrix-commander (PyPI): affected all versions up to 8.0.6; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/GHSA-wchh-9x6h-7f6p/ (Markdown: https://insights.sbomify.com/GHSA-wchh-9x6h-7f6p/index.md)","id":"GHSA-wchh-9x6h-7f6p","markdown":"https://insights.sbomify.com/GHSA-wchh-9x6h-7f6p/index.md","name":"GHSA-wchh-9x6h-7f6p","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Matrix crypto library","requires_auth":"none","summary":"Vulnerabilities in the libolm cryptographic library allow side-channel attacks and signature malleability, compromising Matrix encryption security.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Problem\n\nMultiple 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.
