CVE-2026-34244Network attack vector

Authenticated internal response disclosure via unvalidated machinery URL

Published Apr 15, 2026 · Updated Apr 15, 2026

SSRF in Weblate before 5.17 allows remote authenticated users to read up to 200 characters from internal HTTP responses. Project-level machinery validation accepts user-configured service URLs, requests private-network targets, and copies response text into errors. The project.edit permission, granted by per-project Administration, is required; exposure is limited to the first 200 response characters.
