Socket identified three compromised @memtensor/memos-cloud-openclaw-plugin versions and one compromised MemoryOS version, all carrying a cross-platform credential stealer. The npm versions were subsequently yanked: the npm packument retains their publication timestamps but no longer exposes tarball metadata; OSV MAL-2026-16476 and GHSA-mhjf-v53x-7p87 retain all three affected versions. The PyPI release was also removed from the registry; deps.dev retains its 2026-09-23T05:25:22Z publication timestamp and OSV MAL-2026-16475 retains the affected version.",
