Technical Analysis

OpenClaw's Discord integration package versions before 2026.9.3 have a missing authorization issue affecting the emoji and sticker upload actions. A sender with permission to invoke these actions can bypass the sender-scoped media policy before loading a local file, causing OpenClaw to read bytes from a local file path that would normally be rejected by the configured media roots. This can lead to out-of-policy local file data being included in outbound emoji or sticker uploads. Exploitation requires access to guild asset actions and knowledge or derivation of a useful local path. The vulnerability does not permit unrestricted filesystem browsing or code execution. The issue is resolved in version 2026.9.3 of @openclaw/discord.

Potential Impact

An attacker with limited permissions (sender permitted to invoke emoji or sticker upload actions) can cause the application to read local files outside the allowed media roots and include their content in outbound uploads. This could lead to unauthorized disclosure of local file contents. However, the vulnerability does not allow arbitrary filesystem browsing or remote code execution.

Mitigation Recommendations

Upgrade to @openclaw/discord version 2026.9.3 or later, where this vulnerability is fixed. No other mitigation is indicated or required.
