CVE-2026-15812

Kronosnet: kronosnet: access control list bypass via link id spoofing on unencrypted dynamic links

Published Jul 21, 2026 CVSS 3.1 · 4.8 Medium EPSS < 1% KEV · Not listed
Description
A vulnerability was found in the internal Access Control List (ACL) subsystem of kronosnet (Version affected: <= 1.34). When the framework is explicitly configured to manage dynamic links (accepting network traffic from any IP address) without network payload encryption, the validation architecture implicitly trusts the link ID provided within incoming data packets. A remote, unauthenticated attacker can exploit this lack of validation by spoofing a legitimate link ID inside crafted network frames. This allows the attacker to fully bypass the ACL framework and inject arbitrary data packets into the application layer, potentially leading to data corruption or service instabilities.
