CVE-2026-77507: Weblate: Object-scoped RSS feeds disclose private change history to unauthorized users
Weblate is a web-based continuous localization platform used to manage software translations. In versions prior to 2026.8, Weblate's object-scoped RSS feeds do not apply the permission checks used elsewhere, allowing unauthorized users to read change-history metadata from private projects and restricted components. On installations that permit anonymous access, this metadata can be retrieved without any authentication. The exposed information can include project and component identities, contributor usernames and full names, action types, timestamps, and translation or unit links, though translated-string content is not included in the feed. Installations using private projects or restricted components are affected. This issue is fixed in version 2026.8.

Frequently Asked Questions
Which installations are affected?
Installations using private projects or restricted components are affected when running a version before 2026.8. Anonymous-access installations allow the exposed metadata to be retrieved without authentication.
What does an attacker need to exploit this issue?
An attacker can request object-scoped RSS feeds over the network. No authentication is required on installations that permit anonymous access.
What information can be exposed through the feeds?
The feeds can disclose private change-history metadata, including project and component identities, contributor usernames and full names, action types, timestamps, and translation or unit links. Translated-string content is not included.
How can the issue be remediated?
Upgrade Weblate to version 2026.8, which fixes the missing permission checks on object-scoped RSS feeds.
