Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Detects unauthorized successful logons resulting from improper authentication implementations.
Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.
Security awareness training instructs users on secure authentication practices and avoiding credential compromise.
Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.
Non-repudiation requires strong authentication mechanisms to irrefutably attribute performed actions to specific individuals or processes.
Session content review can reveal authentication bypasses or failures in session establishment.
Review of authentication-related audit records can detect improper authentication mechanisms or bypasses.
Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Vulnerability in Discord-based remote control feature of AutoHotkey macro directly enables bidirectional C2 via web service (T1102.002), remote access tooling (T1219), AutoHotkey command execution for input simulation (T1059.010), and file ingress via unrestricted uploads/path traversal (T1105).
NVD Description
Natro Macro is an open-source Bee Swarm Simulator macro written in AutoHotkey. Prior to version 1.1.0, anyone with Discord Remote Control set up in a non-private channel gives access to any user with the permission to send message in said…

channel access to do anything on their computer. This includes keyboard and mouse inputs and full file access. This issue has been patched in version 1.1.0.
Deeper analysisAI
CVE-2026-28800 affects Natro Macro, an open-source Bee Swarm Simulator macro written in AutoHotkey, in versions prior to 1.1.0. The vulnerability arises from the use of Discord Remote Control in non-private channels, which improperly grants broad access to users with message-sending permissions in those channels. This flaw is classified under CWE-22 (Path Traversal), CWE-287 (Improper Authentication), and CWE-434 (Unrestricted Upload of File with Dangerous Type), with a CVSS v3.1 base score of 6.4 (AV:N/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H). The issue was published on 2026-03-06.
An attacker who has permission to send messages in a Discord channel where the victim has configured Remote Control can exploit this vulnerability. Exploitation requires the victim to have user interaction, such as approving the remote control session, and involves high attack complexity and high privileges on the attacker's side within the Discord context. Successful exploitation allows the attacker full control over the victim's computer, including simulating keyboard and mouse inputs as well as complete file system access.
The GitHub security advisory at https://github.com/NatroTeam/NatroMacro/security/advisories/GHSA-ph9r-2qjm-ghvg confirms that the issue has been addressed in Natro Macro version 1.1.0, recommending users upgrade to the patched version to mitigate the risk.
