OpenConnect before 2.26 places the webvpn cookie value in the debugging output, which might allow remote attackers to obtain sensitive information by reading this output, as demonstrated by output posted to the public openconnect-devel mailing list.

Security readout for executives and security teams

OpenConnect versions before 2.26 could print the WebVPN cookie in debug output. If that output was saved, shared, or posted publicly, someone could learn a sensitive VPN session value. The business risk is mainly session confidentiality, not direct server takeover. Exposure is most likely where OpenConnect before 2.26 was used with debugging enabled and debug output was stored, emailed, attached to tickets, or posted publicly. Systems without retained or shared debug output have lower practical exposure. Treat this as a targeted cleanup issue for legacy VPN clients and leaked diagnostics. Prioritize environments with old OpenConnect usage, retained debug logs, or public support exchanges involving VPN troubleshooting. Mitigation focus: Upgrade OpenConnect before 2.26 according to vendor or distribution guidance.; Remove or restrict debug output containing WebVPN cookie values.; Redact VPN cookies before sharing logs or mailing-list diagnostics..
