Description

This security bulletin contains information about 1 vulnerability.


1) Improper access control (CVE-ID: CVE-2026-73281)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: 5.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to bypass intended local-only restrictions on agent operations.

The vulnerability exists due to improper access control in ssh-agent session binding handling when processing forwarded agent binding requests while the agent is locked. A remote user can send crafted requests through a forwarded agent to bypass intended local-only restrictions on agent operations.

This may permit adding PKCS#11 tokens and using keys with destination restrictions through a forwarded agent.
