CVE-2026-33212Network attack vector

Authenticated task-log disclosure via missing scope check

Published Apr 15, 2026 · Updated Apr 15, 2026

Improper access control in Weblate before 5.17 allows remote authenticated users to read pending-task logs through the tasks API. The get_task path in weblate/api/views.py treated a pending Celery result as lacking component context, so the component access check did not run before task data was returned. Exploitation requires guessing a live task's random UUID, and default API rate limits make repeated guesses impractical.
