CVE-2026-82384: CWE-502: Deserialization of Untrusted Data in Apache Software Foundation Apache Roller
Deserialization of Untrusted Data in Apache Roller 6.1.5 allows an unauthenticated remote attacker to cause deserialization of attacker-controlled bytes, because the XML-RPC endpoint accepts vendor extension types that are deserialized during request parsing, before authentication. The servlet is mapped unconditionally, so parsing occurs even when the global XML-RPC feature is set to disabled; no non-default configuration is required for this path. This can lead to remote code execution. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which disables the extension types and rejects requests when the XML-RPC feature is disabled.
AI Analysis
Technical Summary
CVE-2026-82384 is a critical vulnerability in Apache Roller version 6.1.5 involving deserialization of untrusted data (CWE-502). The XML-RPC endpoint unconditionally accepts vendor extension types that are deserialized during request parsing prior to authentication. This endpoint is mapped regardless of the global XML-RPC feature setting, allowing exploitation even if XML-RPC is disabled. Exploitation can lead to remote code execution. The vulnerability is fixed in Apache Roller 6.1.6 and later, which disables the vulnerable extension types and rejects requests when XML-RPC is disabled.
Potential Impact
An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary code on the affected system due to unsafe deserialization of attacker-controlled data. This compromises confidentiality, integrity, and availability of the system running Apache Roller 6.1.5.
Mitigation Recommendations
Users should upgrade to Apache Roller version 6.1.6 or later, where the vulnerable extension types are disabled and requests are rejected if the XML-RPC feature is disabled. This official fix effectively mitigates the vulnerability.
