CVE-2026-82386 Details
Description
Improper Restriction of XML External Entity Reference in Apache Roller 6.1.5 allows a weblog administrator to read files readable by the Roller process and reach internal network addresses by importing a crafted OPML document, because the bookmark import parser does not disable external entity resolution. No non-default configuration is required; the import is reached through the administrator bookmark-import action. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which uses a hardened parser that disables external entities and document type declarations.
A vulnerability in Apache Roller version 6.1.5 allows weblog administrators to read files accessible to the Roller process and access internal network addresses. This is achieved by importing a specially crafted OPML document, as the bookmark import parser fails to disable external entity resolution. The issue does not require any non-default configuration and can be exploited through the administrator's bookmark-import action.
Users are advised to upgrade to Apache Roller version 6.1.6 or later, which includes a revised parser that disables external entities and document type declarations.
