CVE-2026-84713— Automation-controller: automation-controller: notification.recipients/subject/error lack prevent_search, allowing zero-privilege cross-tenant recovery of notification recipient secrets via filter oracle

Quick assessment

Affected
Red Hat Red Hat Ansible Automation Platform 2.7
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

发现了一个在 automation-controller 通知子系统中的一个漏洞。尽管 NotificationTemplate.notification_configuration 受到 API 过滤的保护，但其 recipient 值在每次发送时都以明文形式复制到未保护的 Notification.recipients 字段中。由于 credential-types 端点可由任何经过身份验证的用户列出，并且 API 过滤器后端在不进行逐跳授权的情况下遍历对象关系，因此没有特权的用户可以使用关系过滤器作为布尔计数

Vulnerability Title
Automation-controller: automation-controller: notification.recipients/subject/error lack prevent_search, allowing zero-privilege cross-tenant recovery of notification recipient secrets via filter oracle
Source: CVE Program / CVE List V5
Vulnerability 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.
