NVD 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.

🚨 Critical - Apache Roller XML-RPC RCE and Authorization Bypass (CVE-2026-82384, CVE-2026-82377) Apache Roller 6.1.5 has two serious XML-RPC flaws: CVE-2026-82384 allows unauthenticated attackers to trigger pre-auth deserialization of attacker-controlled data, potentially leading to RCE, even when global XML-RPC is disabled. CVE-2026-82377 allows authenticated users to read, modify, or delete content in other weblogs when global XML-RPC is enabled, due to missing per-weblog authorization checks. 👉 Affected: Apache Roller 6.1.5 | Upgrade to 6.1.6
