CVE-2026-82376 Details
Description
Improper Restriction of XML External Entity Reference in Apache Roller 6.1.5 allows a user with entry-editing rights on a weblog to cause the server to parse an attacker-influenced trackback response with an XML parser that does not disable external entity resolution, leading to disclosure of files readable by the Roller process. The Trackback control is hidden in the standard UI, but its action remains directly reachable, and no non-default server configuration is required. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which removes the outbound trackback response parser.
A vulnerability in Apache Roller version 6.1.5 allows users with entry-editing rights to exploit the trackback response parser. The XML parser used does not disable external entity resolution, which can lead to the disclosure of files accessible by the Roller process. Although the Trackback control is not visible in the standard user interface, its functionality can still be accessed directly. This vulnerability does not require any special server configuration.
Users are advised to upgrade to Apache Roller version 6.1.6 or later, which removes the outbound trackback response parser.
