Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Versions of neuro-cortex-memory before 3.18.0 are affected. The Cortex visualization tool treats the directory a user has open in Claude Code as a trusted Cortex source root when it finds two marker files there, so a malicious project can get attacker-chosen Python code run with the victim's local user privileges when the victim invokes the open_visualization tool. Upgrade neuro-cortex-memory to version 3.18.0 or later.
