CVE-2026-82377 Details
Description
Missing Authorization in Apache Roller 6.1.5 allows an authenticated user to read, modify, or delete weblog content belonging to other weblogs through the legacy XML-RPC Blogger and MetaWeblog APIs, because the handlers authenticate the caller but do not verify the caller's permission on the weblog or entry actually affected. Only installations that enable the non-default global XML-RPC setting are affected; the per-weblog API flag defaults to enabled for UI-created weblogs. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which applies an explicit per-method permission check, or to keep the XML-RPC feature disabled.
A vulnerability in Apache Roller version 6.1.5 allows authenticated users to read, modify, or delete content on other weblogs via the legacy XML-RPC Blogger and MetaWeblog APIs. The issue arises because the handlers authenticate users but fail to check their permissions on the specific weblog or entry involved. This vulnerability affects only installations with the global XML-RPC setting enabled, as the per-weblog API flag is usually turned on for weblogs created through the user interface.
Users are advised to upgrade to Apache Roller version 6.1.6 or later, which includes a per-method permission check, or to disable the XML-RPC feature.
