# CVE-2026-118405: Apache Roller: Exposure of other users' email addresses through the user 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 any logged-in user to learn other users' email addresses. The user search in the authoring interface shows only user names, but it also matched the search text against email addresses, so a user could confirm an address one character at a time. Users are recommended to upgrade to Apache Roller 6.1.7 or later, which matches only user names for users who are not administrators.
