What is CVE-2026-33212?

Weblate, a web-based localization tool, contains a vulnerability in its tasks API that fails to properly validate user access for pending tasks. This security weakness allows unauthorized users to potentially view logs of ongoing operations, which should be restricted according to the task's access scope. While the exploitation of this issue requires brute-forcing the random UUID of the task, making it unlikely under normal API rate limits, it still poses a risk. The problem has been addressed in version 5.17, emphasizing the importance of upgrading to protect sensitive information.
