GHSA-39mp-545q-w789: OpenClaw: Non-owner command-authorized sender can change the owner-only `/send` session delivery policy
Fixed in OpenClaw 2026.3.24, the current shipping release.**Title**  
Non-owner command-authorized sender can change the owner-only `/send` session delivery policy**CWE**  
CWE-285 Improper Authorization**CVSS v3.1**  
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L  
Base score: **5.4 (Medium)****Severity Assessment**  
Medium. This is a real owner-only authorization bypass, but the demonstrated impact is limited to persistent mutation of the current session’s delivery policy rather than direct code execution, sandbox escape, or cross-host compromise.**Impact**  
A non-owner sender who is allowed to run commands can invoke `/send on|off|inherit` and persistently change the current session’s `sendPolicy`, even though OpenClaw documents `/send` as owner-only.That lets a lower-trust participant:disable reply delivery for the current session (`/send off`), suppressing future replies in that chat;re-enable reply delivery (`/send on`) after the owner intentionally disabled it;remove the session override (`/send inherit`).**Affected Component**  
Verified against the latest published GitHub release tag `v2026.3.23` (`ccfeecb6887cd97937e33a71877ad512741e82b2`), published `2026-03-23T23:15:50Z`.Exact vulnerable path on the shipped tag:`src/auto-reply/reply/commands-session.ts:212-239``handleSendPolicyCommand(...)` checks only `params.command.isAuthorizedSender`.when true, it mutates `params.sessionEntry.sendPolicy` and persists the session entry.Authorization behavior that makes this reachable:`src/auto-reply/command-auth.ts:401-407``senderIsOwner` is computed separately from general command authorization.`src/auto-reply/command-auth.ts:420-429`command authorization can succeed even when `senderIsOwner === false`.`src/auto-reply/command-auth.owner-default.test.ts:10-47`existing coverage confirms a sender can be command-authorized while not treated as owner.Documented owner-only contract:`docs/tools/slash-commands.md:112``/send on|off|inherit` is documented as owner-only.`docs/concepts/session-tool.md:156``sendPolicy` is documented as settable via `sessions.patch` or owner-only `/send on|off|inherit`.Related privilege model:`src/gateway/method-scopes.ts:131-133``sessions.patch` is admin-scoped, which reinforces that session-delivery-policy mutation is treated as privileged state.Version history:The vulnerable handler exists in release history going back at least to commit `ea018a68ccb92dbc735bc1df9880d5c95c63ca35` (`refactor(auto-reply): split reply pipeline`).Earliest released affected tag found: `v2026.1.14-1`Latest released affected tag verified: `v2026.3.23`**Technical Reproduction**Check out the shipped release tag `v2026.3.23`.Configure a channel where:a non-owner sender is allowed to run commands, for example through `commands.allowFrom`;the owner identity is distinct, for example via `commands.ownerAllowFrom`.Start or reuse a session with a live `sessionEntry` and `sessionStore`.Send `/send off` as the non-owner but command-authorized sender.Confirm the resolved command context has:`isAuthorizedSender === true``senderIsOwner === false`Observe that the handler still accepts the command, mutates `sessionEntry.sendPolicy`, and persists the session entry.**Demonstrated Impact**  
The vulnerable handler performs a real persistent session-state change:`src/auto-reply/reply/commands-session.ts:232-238``/send inherit` deletes `sessionEntry.sendPolicy`other modes assign `sessionEntry.sendPolicy = sendPolicyCommand.mode`the handler then calls `persistSessionEntry(params)`The mutation is not gated by owner status, only by general command authorization.That changes subsequent delivery behavior for the current session, which matches the documented meaning of `sendPolicy`.**Environment**Product: OpenClawVerified shipped tag: `v2026.3.23`Shipped tag commit: `ccfeecb6887cd97937e33a71877ad512741e82b2`Published GitHub release time: `2026-03-23T23:15:50Z`Verification date: `2026-03-24`**Duplicate Check**  
Upon inspection there is no preexisting GHSA for `/send`.This is distinct from:`GHSA-r7vr-gr74-94p8`that advisory covered owner-only authorization bypasses for `/config` and `/debug`, not `/send`.This is the same authorization class, but a different privileged command surface that still lacks the owner check.**In Scope Check**  
This report is in scope under `SECURITY.md` because:it does **not** rely on adversarial operators sharing one gateway host or config;it does **not** rely on trusted local state tampering;`SECURITY.md:151-152` explicitly says non-owner sender status matters for owner-only tools and commands;`/send` is explicitly documented as owner-only, so this is a direct owner-only authorization bypass, not a complaint about normal shared-agent steering.This is therefore a concrete authorization flaw against a documented product boundary.**Remediation Advice**Change `/send` to require owner status, not just command authorization.Reuse the same owner-only rejection pattern already used by privileged command surfaces such as `/config`, `/debug`, and owner-only `/plugins` writes.Add regression coverage for the exact case where:a non-owner sender is command-authorized;`/send` must still be rejected unless `senderIsOwner === true`.Verify that the owner can still use `/send on|off|inherit` normally.
