OpenClaw has a Discord `allowFrom` slug-collision authorization bypass

Moderate severity GitHub Reviewed Published Feb 23, 2026 in openclaw/openclaw

Package

npm openclaw (npm)

Affected versions

<= 2026.2.21-2

Patched versions

2026.2.22

Description

OpenClaw supports Discord allowlists using either user IDs or names/tags. Name/tag matching depends on slug normalization, so different user tags can collide to the same slug and unintentionally satisfy a name-based allowlist entry.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected versions: <= 2026.2.21-2
  • Patched versions: >= 2026.2.22

What Changed

  • openclaw security audit now warns on Discord name/tag allowlist entries (DM allowlists, guild/channel users, and pairing-store entries).
  • Runtime authorization now prefers resolved user IDs when a configured name/tag can be resolved, without rewriting config files on disk.
  • Name-based entries remain supported for compatibility.

Recommendations

  • Prefer stable Discord user IDs for security-sensitive allowlists.
  • Run openclaw security audit and address warnings where practical.

OpenClaw thanks @tdjackey for reporting.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
