CVE-2026-28800
Published: 06 March 2026
Summary
CVE-2026-28800 is a medium-severity Path Traversal (CWE-22) vulnerability in Natroteam Natro Macro. Its CVSS base score is 6.4 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Bidirectional Communication (T1102.002); ranked at the 18.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AC-17 (Remote Access) and AC-3 (Access Enforcement).
Deeper analysis
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.

Directly enforces authorization decisions so that only explicitly permitted principals can activate or use the Discord Remote Control feature.
Requires explicit security controls and authentication for all remote-access methods, eliminating exposure of the macro's control channel in non-private Discord channels.
Mandates identification and authentication of non-organizational users before granting access to the remote-control capability, addressing the CWE-287 flaw.
