CVE-2026-62249— Weblate: Restricted-component change history leaked to non-member project users through the nested `GET /api/projects/{slug}/changes/` endpoint

Quick assessment

Affected
WeblateOrg weblate
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.

Weblate 是一个基于 Web 的持续本地化平台，用于管理软件翻译。在 2026.7 之前的版本中，拥有项目访问权限的已认证用户可以通过嵌套的 API 变更端点，获取该项目中受限制组件的变更历史，即使他们没有被直接授予查看这些组件的权限。由于嵌套端点未应用直接组件视图所执行的组件级访问控制检查，请求者能够枚举本应对他们隐藏的组件的变更。所暴露的数据可能包括：受限制组件的身份信息、翻译和单元链接，以及变更负载字段，例如目标语言中的源字符串或翻译字符串内容、旧值以及详情值。该问题已在 2026.7 版本中修复。

Vulnerability Title
Weblate: Restricted-component change history leaked to non-member project users through the nested `GET /api/projects/{slug}/changes/` endpoint
Source: CVE Program / CVE List V5
Vulnerability Description
Weblate is a web-based continuous localization platform used to manage software translations. In versions prior to 2026.7, an authenticated user with access to a project can retrieve the change history of restricted components in that project through nested API change endpoints, even without permission to view those components directly. The nested endpoints do not apply the component-level access checks enforced on the direct component views, so the requester can enumerate changes for components that should be hidden from them. The exposed data can include the restricted component's identity, translation and unit links, and change payload fields such as source or translated string content in the target, old, and details values. This issue is fixed in version 2026.7.
