Vulnerability from github – Published: 2023-09-06 18:30 – Updated: 2024-01-25 18:30A vulnerability in the RADIUS message processing feature of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to cause the affected system to stop processing RADIUS packets.
This vulnerability is due to improper handling of certain RADIUS accounting requests. An attacker could exploit this vulnerability by sending a crafted authentication request to a network access device (NAD) that uses Cisco ISE for authentication, authorization, and accounting (AAA). This would eventually result in the NAD sending a RADIUS accounting request packet to Cisco ISE. An attacker could also exploit this vulnerability by sending a crafted RADIUS accounting request packet to Cisco ISE directly if the RADIUS shared secret is known. A successful exploit could allow the attacker to cause the RADIUS process to unexpectedly restart, resulting in authentication or authorization timeouts and denying legitimate users access to the network or service. Clients already authenticated to the network would not be affected.
Note: To recover the ability to process RADIUS packets, a manual restart of the affected Policy Service Node (PSN) may be required. For more information, see the Details ["#details"] section of this advisory.

GHSA-67C9-F6V2-QV86
Vulnerability from github – Published: 2026-09-17 20:30 – Updated: 2026-09-17 20:30Summary
Steeltoe's Consul discovery client parses the secure metadata field on each registered service instance using bool.Parse, which throws on any value other than true or false. A single service instance registered with a malformed secure value (for example yes or 1) aborts construction of the entire instance list for that service, making the service undiscoverable. When GetAllInstancesAsync is used, one malformed instance in any service can abort enumeration across all services.
This is the same "one malformed field aborts the whole batch" availability class as CVE-2026-50196, but affecting the Consul discovery client.
Impact
Any principal that can register a service in the Consul catalog can trigger a service-discovery outage for all Steeltoe applications resolving that service. The outage affects all instances of the targeted service — not just the malformed one — and persists until the offending registration is removed.
Affected configuration
- Application uses
ConsulDiscoveryClient(any deployment). - The Consul catalog contains at least one service instance with a
securemetadata value that is nottrueorfalse. - Mixed-platform environments where non-.NET clients register services with non-standard metadata values are more likely to encounter this condition.
Mitigations
If an immediate upgrade is not possible:
- Audit the Consul catalog for service registrations with non-standard
securemetadata values. - Restrict write access to the Consul service registration API to trusted services.
