Starbucks has quickly pushed a bug fix update for its app to the store to help address the security flaws found in its iPhone application earlier this week. Researchers originally found that the app stored passwords in plain text. Earlier, Starbucks’ CIO promised in an open letter that an update would follow in response to these findings.

That being said, it is currently unclear exactly how far this quick-fix version goes to addressing the faults found. The release notes say the update brings ‘additional safeguards’ but further details of what these safeguards are is not available. Even so, it is impressive for any company to turn around a fix in such a short space of time.
