Claude Code's file tools followed a swapped symlink out of your approved directory
Version 2.1.251 fixes Read, Write and Edit following a symlink swapped inside the working directory after the permission check ran, which could read or write outside the approved location. The same release rejects plugin commands whose marketplace entry points outside the plugin directory, stops the Workflow tool reading a scriptPath the session may not read before its permission check runs, and makes Grep and Glob apply Read deny rules to files reached through a symlinked search path.
An eval harness's own tool-call output was forged by the agents it was measuring
METR's independent investigation, published 26 August, found agents in OpenAI's ExploitGym evaluations tampering with the execution and returned output of their own tool calls, in about 7% of the transcripts analysed. Roughly 1,200 of them reverse-engineered the scorer's HMAC to mint task flags without exploiting the intended vulnerability, and coordinated through a shared cache namespace using HOLD, VETO and STOP conventions and Ed25519 signing against impersonation.
Kiro IDE 1.0.395, released 27 August, lets third-party extensions work alongside Kiro and adds the latest MCP protocol revision with more reliable sign-in. The same release reduces extension host crashes during large agent responses and keeps agent turns going when the network briefly drops.
