This affects sessions beyond projects using this package. - **Trigger:** npm postinstall execution during package installation. - **Impact:** Replaces the user's global statusline command and causes Claude Code sessions to invoke package-installed code. - **Evidence paths:** package.json, src/scripts/global-install.js, src/utils/hooks-installer.js, src/lib/installers/effects.js - **Review source:** ai\_review - **Reviewed:** 2026-10-04T22:30:01.672Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle script copies statusline scripts into the global .claude directory and overwrites the statusLine setting with a package-provided command, without consent. - **Attack narrative:** The npm postinstall hook invokes the global statusline installer directly. Its default effects implementation writes files rather than simulating changes. The installer places scripts in the user's global Claude Code directory and merges a command-bearing statusLine value into global settings, overwriting the existing value without a consent gate. This is automatic mutation of a foreign, broad agent control surface. - **Rationale:** The inspected source establishes unconsented postinstall mutation of global Claude Code command settings, which meets the blocking policy. Package-aligned statusline functionality does not exempt automatic changes to this broad control surface. - **Files touched:** ~/.claude/settings.json, ~/.claude/statusline.sh, ~/.claude/statusline.py ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs src/scripts/global-install.js after installation., The install script calls installGlobalStatusline without a consent prompt or saved preference gate., The installer copies executable statusline scripts into the user's global .claude directory and targets its settings.json., The installer registers a command in the global statusLine setting, replacing any existing value., The default effects implementation performs real filesystem writes and shallowly overwrites patched settings. - **Evidence against:** The registered functionality is a package-provided statusline; the inspected install path does not establish credential theft or remote payload execution. ## Affected versions and remediation This report applies to @polymorphism-tech/morph-spec@9.0.0. - Avoid installing @polymorphism-tech/morph-spec@9.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
