How to fix
- Fixed in: Apache Roller 6.1.7 or later
Rebuild the search index after upgrading to 6.1.7 to remove the email field entirely; existing indexes will retain the field but the query validation check will prevent access to it.
Technical details
The vulnerability is an information disclosure flaw where comment author email addresses were indexed in the search index and queryable through the public weblog search interface. An attacker can use wildcard queries on the email field to enumerate valid email addresses one character at a time. The fix restricts search queries to only the intended search fields (entry content, title, and comment text) and stops indexing email addresses; existing indexes retain the field but query validation prevents access.
Affected products
- Apache Roller 4.0 through 6.1.6
