CVE-2026-118405 · Severity: medium · CVSS 4.3 · Published 2026-11-11

Apache Roller is a web-based blogging platform used to publish and manage online content. Logged-in users can enumerate other users' email addresses by searching the user interface character-by-character, even though email addresses are not supposed to be visible to regular users. This allows attackers with valid accounts to discover private contact information of other users.

## 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.
