CVE-2026-105140: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') in obot-platform obot
Description
Obot 0.25.0 before 0.25.6 and 0.26.0 before 0.26.1 contains a race condition in auth provider group refreshes that can restore group memberships just revoked in the identity provider. When overlapping refreshes for the same user commit out of order, stale memberships are persisted and the user retains revoked group-based access for about ten minutes.

Technical Analysis
CVE-2026-105140 describes a race condition vulnerability in obot-platform's obot product affecting versions >=0.25.0 <0.25.6 and >=0.26.0 <0.26.1. The issue occurs during concurrent execution of group membership refreshes in the authentication provider, where improper synchronization allows stale group memberships to be persisted. This results in users retaining revoked group-based access temporarily when overlapping refreshes for the same user commit out of order.
Potential Impact
The vulnerability allows users to retain access to groups from which they have been revoked for about ten minutes due to stale membership data being persisted. This could lead to a short window of unauthorized access based on group membership. The CVSS 4.0 score is low (2.3), reflecting limited impact and complexity.
Mitigation Recommendations
A fix is available in obot versions 0.25.6 and 0.26.1 and later. Users should upgrade to these versions to resolve the race condition and prevent temporary retention of revoked group memberships.
