How to fix

Fixed in: Apache Roller 6.1.7

Technical details

The user search feature in the authoring interface matched search text against both usernames and email addresses for non-administrative users, leaking email information through search result inference. An authenticated attacker can confirm email addresses one character at a time by observing whether results match. The fix (Apache Roller 6.1.7) restricts matching to usernames only for non-admins and properly escapes wildcard characters in search queries.

Affected products
