CVE-2026-39845
In versions prior to 5.17, the webhook add-on did not utilize existing SSRF protections.
Does this matter?
Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.
Description
Weblate is a web based localization tool. In versions prior to 5.17, the webhook add-on did not utilize existing SSRF protections. This issue has been fixed in version 5.17. If developers are unable to update immediately, they can disable the webhook add-on as a workaround.
