GHSA-xrwr-fcw6-fmq8: weblate (CVE-2026-34244)

Package	Ecosystem	Affected	Fixed in
weblate	PyPI	<5.17	5.17

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Weblate versions before 5.17 are vulnerable to server-side request forgery through project-level machine translation configuration. A user with the project.edit permission, granted by the per-project Administration role, can point machine translation service URLs at internal network addresses, and up to 200 characters of the response are shown back in an error message. Upgrade to Weblate 5.17 or later. As a workaround, limit the available machinery services with the WEBLATE_MACHINERY setting.
