CVE-2026-106471
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk19th percentile - higher than 19% of all known CVEs
Summary
A flaw was found in Candlepin where the central authorization filter incorrectly grants access when any one of multiple @Verify-annotated parameters is accessible, instead of requiring access to every verified entity. A low-privilege authenticated attacker who can access the first referenced object can bypass authorization checks on subsequent objects. When target resource identifiers are known, this can enable unauthorized disclosure of consumer information and unauthorized modification of entitlements and related subscription resources, including across organizations.
Risk Assessment
An attacker with a basic account can access data from other organizations and modify entitlements and subscriptions, leading to confidentiality and integrity breaches. The risk includes privilege escalation and unauthorized changes in the environment.
Recommendation
Update Candlepin to a version containing the authorization filter fix that requires access to every verified entity. Review access logs for unusual entitlement and subscription operations.
