CVE-2026-84720— Automation-controller: automation-controller: workflowjobnode.ancestor_artifacts lacks prevent_search, exposing no_log set_stats artifacts via orm-traversal count-oracle

Quick assessment

Affected
Red Hat Red Hat Ansible Automation Platform 2.5 for RHEL 8
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.

在 Ansible Automation Platform 的 automation-controller 中发现了一个安全漏洞。WorkflowJobNode 表的 数据库列用于存储在工作流节点之间传播的原始合并的 工件。该列未被 函数包裹保护，因此尽管它在 API 序列化器中被省略（即不通过 API 暴露），REST 过滤器后端仍接受对该列的任意字段查询。 由于该列在 Ansible 的 屏蔽机制应用之前就被持久化存储到数据库中，导致具有工作流只读权限的用户，或者任何通过世界可读的 端点绕过 JSON 跨关系过

Vulnerability Title
Automation-controller: automation-controller: workflowjobnode.ancestor_artifacts lacks prevent_search, exposing no_log set_stats artifacts via orm-traversal count-oracle
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the Ansible Automation Platform automation-controller. The WorkflowJobNode.ancestor_artifacts database column, which stores the raw merged set_stats artifacts propagated between workflow nodes, is not wrapped in prevent_search() and is therefore accepted for arbitrary field lookups by the REST filter backend, even though it is omitted from the API serializer. Because the column is persisted before Ansible's no_log masking is applied, a user with only read access to a workflow — or, via a regular-expression lookup that bypasses the JSON cross-relation filter guard through the world-readable credential-types endpoint, any authenticated user with no roles — can use the result count as a boolean/count oracle to recover, character by character, secret values that a playbook author explicitly marked no_log, including across organizations.
