[Enxin Xie <linkinstar () apache org>]

Severity: moderate

Affected versions:

- Apache Answer through 1.2.0

Description:

Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability in Apache 
Answer.

This issue affects Apache Answer: through 1.2.0.

Under normal circumstances, a user can only bookmark a question once, and will only increase the number of questions 
bookmarked once. However, repeat submissions through the script can increase the number of collection of the question 
many times.

Users are recommended to upgrade to version [1.2.1], which fixes the issue.
