@@ -67,6 +67,7 @@ Docs: https://docs.openclaw.ai
 - Gateway/CLI: when `gateway.bind=lan`, use a LAN IP for probe URLs and Control UI links. (#11448) Thanks @AnonO6.
 - CLI: make `openclaw plugins list` output scannable by hoisting source roots and shortening bundled/global/workspace plugin paths.
 - Hooks: fix bundled hooks broken since 2026.2.2 (tsdown migration). (#9295) Thanks @patrickshao.
+- Security/Plugins: install plugin and hook dependencies with `--ignore-scripts` to prevent lifecycle script execution.
 - Routing: refresh bindings per message by loading config at route resolution so binding changes apply without restart. (#11372) Thanks @juanpablodlc.
 - Exec approvals: render forwarded commands in monospace for safer approval scanning. (#11937) Thanks @sebslight.
 - Config: clamp `maxTokens` to `contextWindow` to prevent invalid model configs. (#5516) Thanks @lailoo.
