DescriptionWeblate is a web based localization tool. In versions prior to 5.17, the tasks API didn't verify user access for pending tasks. This could expose logs of in-progress operations to users who don't have access to given scope. The attacker needs to brute-force the random UUID of the task, so exploiting this is unlikely with the default API rate limits. This issue has been fixed in version 5.17.
