# CVE-2026-118409: Apache Roller: Commenter email addresses recoverable through public search

Status: published. Published: 2026-11-11. Updated: 2026-11-11.

Exposure of Sensitive Information to an Unauthorized Actor in Apache Roller 4.0 through 6.1.6 allows an unauthenticated visitor to recover the email addresses of people who left approved comments. The search index stored commenter email addresses, and the public weblog search accepted queries on that field, including wildcard queries that confirm an address one character at a time. Users are recommended to upgrade to Apache Roller 6.1.7 or later and rebuild the search index.
