OpenClaw Matrix before 2026.8.1 Authorization Bypass via Case Folding
OpenClaw's Matrix integration (npm package @openclaw/matrix) versions >= 2026.2.2 and < 2026.8.1 lowercase complete Matrix user IDs — including historical localparts and the case-sensitive server-name portion — when deriving the OpenClaw authorization identity. As a result, distinct authenticated Matrix accounts can normalize to the same authorization identity. A Matrix participant controlling a colliding account identifier (a protocol-valid identifier that differs from the configured one only by characters OpenClaw case/Unicode folds; display-name matching is not required) can inherit allowlist, owner-command, exec-approval, or plugin-approval authority configured for another account. The issue is fixed in 2026.8.1.
