CVE-2026-105139: Obot-Platform Obot

Medium severity, CVSS 4.3. EPSS: 0.2% chance of exploitation in the next 30 days.

Obot 0.26.0 before 0.26.2 contains an authorization bypass vulnerability that allows authenticated users matching any vMCP profile to reach prompts and resources of ungranted components. Because profiles were enforced only on tools, attackers can access prompts, resources, and resource templates through the vMCP owner's shared component connection.

Affected products

• Obot-Platform Obot: from 0.26.0, before 0.26.2 (fixed in 0.26.2)
