SCA: security update for @anthropic-ai/sdk (GHSA-5474-4w2j-mq4c)

medium Tenable Cloud Security Plugin ID 439667

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Claude SDK for TypeScript provides access to the Claude API from server-side TypeScript or JavaScript
 applications. From version 0.79.0 to before version 0.81.0, 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. This issue has been patched in version 0.81.0. (CVE-2026-34451)

Solution

Update the @anthropic-ai/sdk library and its related packages to version 0.81.0 or later.
