CVE-2026-103869— Pulp-ansible: bearer tokens are reused across remotes in a worker

Quick assessment

Affected
Red Hat Red Hat Ansible Automation Platform 2
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 Pulp-Ansible 在处理集远程（collection remotes）的承载令牌（bearer-token）刷新时存在一个缺陷。访问令牌被保存在一个模块级别的变量中，并在该工作进程中重复用于所有令牌下载操作。攻击者若能同步一个使用令牌刷新的 Ansible 远程，并将该远程指向其控制的服务器，即可获得另一个远程所对应的访问令牌，并在签发该令牌的服务端重复使用此令牌。Pulp 中存储的内容不会被更改，服务也不会中断。

Vulnerability Title
Pulp-ansible: bearer tokens are reused across remotes in a worker
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in pulp-ansible's bearer-token refresh for collection remotes. The access token is kept in one module-level variable and reused for every token download in that worker. A user who can sync an Ansible remote that uses token refresh, and can point that remote at a server they control, receives an access token obtained for a different remote, and can reuse it at the service that issued it. Content stored in Pulp is not changed, and the service is not stopped.
