AI-suggested

Upgrade Apache Roller to version 6.1.6 or later, which implements explicit per-method permission checks to fix the authorization issue. Alternatively, disable the global XML-RPC feature if it is not required, as this feature is non-default and disabling it prevents exploitation of this vulnerability.

Description

Apache Roller 6.1.5 contains a missing authorization vulnerability in its legacy XML-RPC Blogger and MetaWeblog APIs. Authenticated users can read, modify, or delete content from other weblogs because the API handlers authenticate the caller but do not verify permissions on the affected weblog or entry. This issue affects installations with the non-default global XML-RPC setting enabled. The vulnerability is fixed in Apache Roller 6.1.6 by adding explicit per-method permission checks. Users are advised to upgrade or disable the XML-RPC feature to mitigate the risk.
