CVE-2026-81033— Automatisch through 0.15.0 User Enumeration via Forgot-Password Response Discrepancy

Quick assessment

Affected
automatisch automatisch
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.

Automatisch 通过其对“忘记密码”请求的响应，揭示某个邮箱地址是否已注册。位于 的控制器会查询该地址，并在查询链上附加一个“未找到”的异常抛出：若地址无账户，则触发该异常，全局错误处理器将其渲染为“未找到”状态码；若地址已注册，则流程继续以发送重置消息并返回“无内容”状态码。该路由在未认证的情况下挂载。因此，提交候选邮箱地址并比较两种状态码，即可确定哪些地址拥有账户，且该过程中既不需要凭证，也未设置速率限制。

Vulnerability Title
Automatisch through 0.15.0 User Enumeration via Forgot-Password Response Discrepancy
Source: CVE Program / CVE List V5
Vulnerability Description
Automatisch reveals whether an address is registered through the response to its forgot-password request. The controller at packages/backend/src/controllers/internal/api/v1/users/forgot-password.js looks the address up and chains a not-found throw onto the query, so an address with no account raises an error that the global handler renders as a not-found status, while a registered address proceeds to send the reset message and returns no-content. The route is mounted without authentication. Submitting candidate addresses and comparing the two status codes therefore establishes which addresses hold accounts, with no credential and no rate limiting in the path.
