CVE-2026-105152 · Severity: medium · CVSS 4.3 · Published 2026-11-11

Apache Roller is a blogging platform used to create and manage weblogs. A weblog administrator can craft custom templates that bypass security restrictions to access sensitive data, including password hashes of the weblog creator and authors whose entries appear on the page. This allows account takeovers if an attacker gains administrative access to a weblog.

## How to fix

- Fixed in Apache Roller 6.1.7 or later

Restrict weblog administrator template authoring privileges to trusted users only, as this vulnerability requires that an attacker have the ability to author custom weblog templates.

## Technical details

The vulnerability exists in Roller's template wrapper classes (WeblogWrapper and WeblogEntryWrapper), which exposed public getPojo() accessor methods that returned the underlying persistent objects directly rather than the restricted interface intended for templates. Weblog templates are rendered under Velocity's SecureUberspector, which should limit method access, but the public accessors bypassed this restriction. An authenticated weblog administrator can exploit this to read password hashes and other sensitive fields from wrapped objects.

## Affected products
