CVE-2026-101062 obot-platform CVE debrief

Who should care

Defenders responsible for Obot instances, particularly those exposed to untrusted networks or used by multiple users, should assess their exposure and take mitigation steps. This includes verifying the current Obot version, restricting access to Obot API endpoints, and monitoring for suspicious activity. Additionally, defenders should review their incident response plans to ensure they can respond quickly in case of an attack. Those managing Obot instances

Why it matters

CVE-2026-101062 is a high-severity vulnerability in Obot versions before v0.23.0 that allows for authentication bypass via OAuth dynamic client registration. Defenders should prioritize verifying exposure, restricting access, and upgrading to mitigate the vulnerability.

• An attacker can obtain unauthorized access to victim's resources
• Victim's resources can be read or modified until token revocation
• Defenders must verify Obot instance exposure and upgrade to v0.23.0 or later
• Authentication and authorization mechanisms require reevaluation

Technical summary

The vulnerability exists in Obot versions before v0.23.0 when running with OBOT_SERVER_ENABLE_AUTHENTICATION=true. OAuth dynamic client registration is exposed without authentication and without restrictions on redirect URIs. An attacker can register a client pointing at their own domain and induce a logged-in victim to visit a crafted authorization URL, receiving an authorization code at the attacker-controlled redirect URI. This code can be exchanged for an access token and refresh token, allowing the attacker to read or modify the victim's resources until the token is revoked.

Defensive priority

Defenders should prioritize verifying exposure of Obot instances to untrusted networks, restricting access to Obot API endpoints, and upgrading to v0.23.0 or later.

Recommended defensive actions

• Verify Obot instance exposure to untrusted networks
• Restrict access to Obot API endpoints
• Upgrade to Obot v0.23.0 or later
• Monitor for suspicious authorization requests
• Perform vulnerability scanning to identify exposed Obot instances
• Review access controls for Obot API endpoints
• Implement additional logging and monitoring for Obot instance activity
