UBUNTU-CVE-2026-57218
RabbitMQ versions prior to 4.2.6 contain a vulnerability in the AMQP 0-9-1 protocol where an existing consumer continues to receive messages even after the OAuth token expires or its scopes are reduced via connection.update_secret. This occurs because consumers are not canceled or reauthorized when the channel user state changes. The issue is fixed in RabbitMQ version 4.2.6.
AI Analysis
Technical Summary
RabbitMQ AMQP 0-9-1 protocol implementations before version 4.2.6 allow existing consumers to keep receiving messages after OAuth token expiry or scope reduction via connection.update_secret refresh. This happens because the consumers are not canceled or reauthorized at delivery time following changes in the channel user state. The vulnerability is resolved in version 4.2.6.
Potential Impact
An attacker or user with an expired or reduced-scope OAuth token may continue to receive messages they should no longer be authorized to access, potentially leading to unauthorized message consumption. There is no indication of privilege escalation or broader system compromise from the provided data.
Mitigation Recommendations
Upgrade RabbitMQ to version 4.2.6 or later, where this issue is fixed. No other mitigations are indicated. Patch status is confirmed by the vendor advisory stating the fix is in version 4.2.6.
