Discovering and exploiting a remote code execution vulnerability in OpenCode (GHSA-632h-h47v-g4x4)

Datadog Security Labs discovered GHSA-632h-h47v-g4x4 in OpenCode, where a content-type confusion bug in the /global/upgrade endpoint let attackers trigger remote code execution by serving a malicious npm tarball through a crafted cross-origin HTML form submission. OpenCode 1.18.22 fixes the issue, which affected versions 1.14.30 through 1.18.21 when installed via npm, pnpm, or Bun. #OpenCode #GHSA-632h-h47v-g4x4 #Anomaly #DatadogSecurityLabs

MemTensor npm and PyPI Packages Compromised in Credential-Stealing Supply Chain Attack

Malicious releases of MemTensorโ€™s @memtensor/memos-cloud-openclaw-plugin and MemoryOS package were published on npm and PyPI, respectively, and they drop a cross-platform Go payload named sckit that searches developer home directories for secrets and sends them to C2 infrastructure under skyleen[.]fr. The compromise spans GitHub repository commits, registry releases, and release-tooling changes, putting users, CI runners, and developer machines at risk while exposing tokens and credentials from services such as GitHub, GitLab, AWS, Vault, SSH, and PyPI. #MemTensor #MemOS #OpenClaw #MemoryOS #sckit #skyleenfr
