CVE-2026-34999: Volcengine Openviking

Medium severity, CVSS 5.3. EPSS: 0.8% chance of exploitation in the next 30 days.

OpenViking versions 0.2.5 prior to 0.2.14 contain a missing authentication vulnerability in the bot proxy router that allows remote unauthenticated attackers to access protected bot proxy functionality by sending requests to the POST /bot/v1/chat and POST /bot/v1/chat/stream endpoints. Attackers can bypass authentication checks and interact directly with the upstream bot backend through the OpenViking proxy without providing valid credentials.

Affected products

• Volcengine Openviking: from 0.2.5, before 0.2.14 (fixed in 0.2.14)
