Firewall rule inheritance bypass in Cisco Terminal Services (TS) Agent allows an authenticated remote attacker to escape their own firewall policy and operate under the network access rules of a different user account. Affected versions span TSAgent-1.0 through TSAgent-1.4.2 per EUVD-2026-53447. No public exploit code has been identified at time of analysis and the vulnerability is not listed in the CISA KEV catalog, but the low attack complexity and network-accessible vector make it straightforward to attempt for any credentialed user in an affected deployment.
