## Overview

### Impact
The API for tasks 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.

### Patches
* https://github.com/WeblateOrg/weblate/pull/18515

### Workarounds
The attacker needs to guess the random UUID of the task, so exploiting this is unlikely with the default API rate limits.

### References
This issue was identified by Michal Čihař.

## Affected packages

- `weblate < 5.17`

## Remediation

Upgrade to a patched release:

- `weblate 5.17`
