The practical impact depends on your Matrix channel policies and what capabilities are enabled downstream.\n\n### Mitigation\n\n- Upgrade to `openclaw >= 2026.2.2`.\n- Ensure Matrix allowlists contain only full Matrix user IDs (MXIDs) like `@user:server` (or `*`). Do not use display names or bare localparts.\n\n### Fix Commit(s)\n\n- `8f3bfbd1c4fb967a2ddb5b4b9a05784920814bcf`\n\n### Release Process Note\n\nThe patched version is already published to npm; the advisory can be published once you're ready.\n\nThanks @MegaManSec (https://joshua.hu) of [AISLE Research Team](https://aisle.com/) for reporting.", "title": "osv -
