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.

Read the publisher's advisory## Summary In 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. ## Details Nextcloud 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. ## Affected Packages / Versions - Package: `@openclaw/nextcloud-talk` (npm) - Affected: `<= 2026.2.2` - Fixed: `>= 2026.2.6` Note: This advisory applies to the optional Nextcloud Talk plugin package. Core `openclaw` is not impacted unless you installed and use `@openclaw/nextcloud-talk`. ## Fix Commit(s) - [6b4b6049b47c3329a7014509594647826669892d](https://github.com/openclaw/openclaw/commit/6b4b6049b47c3329a7014509594647826669892d) ## Timeline - Introduced: [660f87278c9f292061e097441e0b10c20d62b31b](https://github.com/openclaw/openclaw/commit/660f87278c9f292061e097441e0b10c20d62b31b) (2026-01-20) - Fixed in repo: [6b4b6049b47c3329a7014509594647826669892d](https://github.com/openclaw/openclaw/commit/6b4b6049b47c3329a7014509594647826669892d) (2026-02-04 UTC) - First fixed tag containing the change: [v2026.2.3](https://github.com/openclaw/openclaw/releases/tag/v2026.2.3) - First fixed npm release of `@openclaw/nextcloud-talk`: `2026.2.6` (published 2026-02-07 UTC) ## Mitigation Upgrade `@openclaw/nextcloud-talk` to `>= 2026.2.6`. ## Release Process Note The patched version range is set to the first npm release that contains the fix.

Read the publisher's advisoryCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.
A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.
See how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.
Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
