@@ -76,6 +76,7 @@ Docs: https://docs.openclaw.ai
 - Cron/Service: execute manual `cron.run` jobs outside the cron lock (while still persisting started/finished state atomically) so `cron.list` and `cron.status` remain responsive during long forced runs. (#23628) Thanks @dsgraves.
 - Cron/Timer: keep a watchdog recheck timer armed while `onTimer` is actively executing so the scheduler continues polling even if a due-run tick stalls for an extended period. (#23628) Thanks @dsgraves.
 - Cron/Run log: clean up settled per-path run-log write queue entries so long-running cron uptime does not retain stale promise bookkeeping in memory.
+- Cron/Run log: harden `cron.runs` run-log path resolution by rejecting path-separator `id`/`jobId` inputs and enforcing reads within the per-cron `runs/` directory.
 - Cron/Isolation: force fresh session IDs for isolated cron runs so `sessionTarget="isolated"` executions never reuse prior run context. (#23470) Thanks @echoVic.
 - Plugins/Install: strip `workspace:*` devDependency entries from copied plugin manifests before `npm install --omit=dev`, preventing `EUNSUPPORTEDPROTOCOL` install failures for npm-published channel plugins (including Feishu and MS Teams).
 - Feishu/Plugins: restore bundled Feishu SDK availability for global installs and strip `openclaw: workspace:*` from plugin `devDependencies` during plugin-version sync so npm-installed Feishu plugins do not fail dependency install. (#23611, #23645, #23603)
