CVE-2026-84713
Description
A flaw was found in the automation-controller notification subsystem. Although NotificationTemplate.notification_ configuration is protected from API filtering, its recipient value is copied in clear text into the unprotected Notification.recipients field on every send. Because the credential-types endpoint is listable by any authenticated user and the API filter backend traverses object relations without per-hop authorization, a user with no privileges can use a relational filter as a boolean count-oracle to recover, character by character and across organizations, the secret recipient values of other tenants' notifications — including PagerDuty service keys and Slack/Mattermost/RocketChat/Webhook bearer-token URLs. This flaw affects confidentiality.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Access Control
Technical Impact: Bypass Protection Mechanism
Access control checks for specific user data or functionality can be bypassed.
Access Control
Technical Impact: Gain Privileges or Assume Identity
Horizontal escalation of privilege is possible (one user can view/modify information of another user).
Access Control
Technical Impact: Gain Privileges or Assume Identity
Vertical escalation of privilege is possible if the user-controlled key is actually a flag that indicates administrator status, allowing the attacker to gain administrative access.
