CVE-2026-111456 · Severity: high · CVSS 7.1 · Published 2026-11-12

Candlepin is a subscription management system used by Red Hat Satellite to manage software entitlements and subscriptions. An attacker with a valid consumer certificate from one organization can bypass authorization checks to register new consumers in a different organization, gaining access to that organization's subscription pools and potentially its entitlements. This allows unauthorized access to subscription benefits and subscription data across organizational boundaries.

## Technical details

The ConsumerResource.setupOwner() function in Candlepin's consumer registration module performs authorization checks only for user-authenticated callers, not for certificate-authenticated consumers. An attacker with a valid consumer identity certificate can supply an arbitrary organization key to register a new consumer in a different organization, bypassing the permission check. The attacker then receives an identity certificate for the new consumer, allowing access to the target organization's subscription pools and entitlements.
