NVD description
OpenClaw's Nextcloud Talk plugin versions prior to 2026.2.6 accept equality matching on the mutable actor.name display name field for allowlist validation, allowing attackers to bypass DM and room allowlists. An attacker can change their Nextcloud display name to match an allowlisted user ID and gain unauthorized access to restricted conversations.
What to do
- Upgrade OpenClaw to
2026.2.6or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
