Open advisories
2 actionable advisories, newest first. Withdrawn advisories and news are excluded. Coverage is partial.
The BetaLocalFilesystemMemoryTool in the Anthropic TypeScript SDK created memory files and directories using the Node.js default modes (0o666 for files, 0o777 for directories), leaving them world-readable on systems with a standard umask and world-writable in environments with a permissive umask such as many Docker base images. A local attacker on a shared host could read persisted agent state, and in containerized deployments could modify memory files to influence subsequent model behavior. Users on the affected versions are advised to update to the latest version. Claude SDK thanks lucasfutures for the report.
Recommended action: Upgrade to 0.91.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
The local filesystem memory tool in the Anthropic TypeScript SDK validated model-supplied paths using a string prefix check that did not append a trailing path separator. A model steered by prompt injection could supply a crafted path that resolved to a sibling directory sharing the memory root's name as a prefix, allowing reads and writes outside the sandboxed memory directory. Users on the affected versions are advised to update to the latest version. Claude SDK for TypeScript thanks hackerone.com/nicksim for reporting this issue!
Recommended action: Upgrade to 0.81.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
