Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls @openclaw/nextcloud-talk
How to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2026-28474, inspect your project dependencies using npm:
npm ls @openclaw/nextcloud-talk

"details" : "## Summary\n\nIn affected versions of the optional Nextcloud Talk plugin (installed separately; not bundled with the core OpenClaw install), an untrusted webhook field (`actor.name`, display name) could be treated as an allowlist identifier. An attacker could change their Nextcloud display name to match an allowlisted user ID and bypass DM or room allowlists.\n\n## Details\n\nNextcloud Talk webhook payloads provide a stable sender identifier (`actor.id`) and a mutable display name (`actor.name`). In affected versions, the plugin’s allowlist matching accepted equality on the display name, which is attacker-controlled.\n\n## Affected Packages / Versions\n\n- Package: `@openclaw/nextcloud-talk` (npm)\n- Affected: `<= 2026.2.2`\n- Fixed: `>= 2026.2.6`\n\nNote: This advisory applies to the optional Nextcloud Talk plugin package. Core `openclaw` is not impacted unless you installed and use `@openclaw/nextcloud-talk`.\n\n## Fix Commit(s)\n\n- [6b4b6049b47c3329a7014509594647826669892d](https://github.com/openclaw/openclaw/commit/6b4b6049b47c3329a7014509594647826669892d)\n\n## Timeline\n\n- Introduced: [660f87278c9f292061e097441e0b10c20d62b31b](https://github.com/openclaw/openclaw/commit/660f87278c9f292061e097441e0b10c20d62b31b) (2026-01-20)\n- Fixed in repo: [6b4b6049b47c3329a7014509594647826669892d](https://github.com/openclaw/openclaw/commit/6b4b6049b47c3329a7014509594647826669892d) (2026-02-04 UTC)\n- First fixed tag containing the change: [v2026.2.3](https://github.com/openclaw/openclaw/releases/tag/v2026.2.3)\n- First fixed npm release of `@openclaw/nextcloud-talk`: `2026.2.6` (published 2026-02-07 UTC)\n\n## Mitigation\n\nUpgrade `@openclaw/nextcloud-talk` to `>= 2026.2.6`.\n\n## Release Process Note\n\nThe patched version range is set to the first npm release that contains the fix. Once you are ready, you can publish this advisory without additional version edits.\n\nThanks @MegaManSec (https://joshua.hu) of [AISLE Research Team](https://aisle.com/) for reporting.",
