Summary
OpenClaw: Plugin subagent routes could bypass gateway authorization with synthetic admin scopes
Details

Summary

In affected versions of openclaw, the plugin subagent runtime dispatched gateway methods through a synthetic operator client that always carried broad administrative scopes. Plugin-owned HTTP routes using auth: "plugin" could therefore trigger admin-only gateway actions without normal gateway authorization.

Impact

This is a critical authorization bypass. An external unauthenticated request to a plugin-owned route could reach privileged subagent runtime methods and perform admin-only gateway actions such as deleting sessions, reading session data, or triggering agent execution.

Affected Packages and Versions

  • Package: openclaw (npm)
  • Affected versions: >= 2026.3.7, < 2026.3.11
  • Fixed in: 2026.3.11

Technical Details

The new plugin subagent runtime preserved neither the original caller's auth context nor least-privilege scope. Instead, it executed gateway dispatches through a fabricated operator client with administrative scopes, which was reachable from plugin-owned routes that intentionally bypass normal gateway auth so plugins can perform their own webhook verification.

Fix

OpenClaw now preserves real authorization boundaries for plugin subagent calls instead of dispatching them through synthetic admin scopes. The fix shipped in openclaw@2026.3.11.

Workarounds

Upgrade to 2026.3.11 or later.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
