CVE-2026-29226: Apache OFBiz SSRF Vulnerability

CVE-2026-29226 Overview

CVE-2026-29226 is a Server-Side Request Forgery (SSRF) vulnerability in Apache OFBiz. The flaw resides in the Content component operations and affects all versions before 24.09.06. Apache OFBiz is an open source enterprise resource planning (ERP) suite providing customer relationship management, e-commerce, and supply chain functionality. The vulnerability allows unauthenticated attackers to coerce the OFBiz server into issuing arbitrary HTTP requests to internal or external destinations. The Apache OFBiz project has released version 24.09.06 to address the issue.

Critical Impact

An unauthenticated remote attacker can leverage the Content component to make the OFBiz server send crafted requests, enabling reconnaissance of internal networks, interaction with internal services, and potential exposure of metadata endpoints in cloud deployments.

Affected Products

• Apache OFBiz versions before 24.09.06
• All deployments exposing the Content component to network-reachable clients
• Cloud-hosted OFBiz instances with access to internal metadata services

Technical Details for CVE-2026-29226

Vulnerability Analysis

The vulnerability is classified as Server-Side Request Forgery [CWE-918]. It exists in operations exposed by the Apache OFBiz Content component. The component accepts user-supplied input that is incorporated into outbound HTTP requests without sufficient validation of the destination URL.

An attacker can submit a crafted request that instructs the OFBiz server to fetch a resource from an arbitrary URL. Because the request originates from the server, it can reach hosts and ports that are otherwise unreachable from the public network. This includes internal management interfaces, databases, and cloud instance metadata endpoints.

The attack vector is network-based and requires no authentication or user interaction. Confidentiality, integrity, and availability impacts are all rated low, reflecting limited direct data access while still enabling pivoting and reconnaissance.

Root Cause

The root cause is missing or insufficient validation of URLs supplied to Content component operations. The component dereferences attacker-controlled destinations during normal content retrieval workflows. Allowlist enforcement on outbound hosts and protocols is not applied before the request is dispatched.

Attack Vector

An attacker sends an HTTP request to a network-reachable OFBiz endpoint exposing a vulnerable Content operation. The request contains a URL pointing to an internal service, a cloud metadata endpoint, or a controlled external collaborator. The OFBiz server issues the outbound request and may return the response body, headers, or error information to the attacker. Refer to the Apache Security Mailing List announcement and the OpenWall OSS-Security discussion for further technical context.

// No verified proof-of-concept is publicly available at this time.

Detection Methods for CVE-2026-29226

Indicators of Compromise

• Outbound HTTP requests from the OFBiz application server to internal IP ranges such as 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16 that are not part of normal application behavior
• Requests from the OFBiz host to cloud metadata addresses such as 169.254.169.254
• Unexpected entries in OFBiz access logs referencing Content component operations with external or loopback URL parameters

Detection Strategies

• Inspect web server and application logs for Content component requests containing URL parameters with non-standard schemes (file://, gopher://) or internal hostnames
• Correlate inbound HTTP requests to OFBiz with outbound network connections from the same process to detect SSRF chaining
• Monitor egress traffic from the OFBiz server and alert on connections to addresses outside an approved destination allowlist

Monitoring Recommendations

• Forward OFBiz application logs and host network telemetry to a centralized analytics platform for correlation
• Deploy egress filtering with logging at the network boundary of the OFBiz host to record all outbound destinations
• Establish a baseline of legitimate outbound destinations from the OFBiz service and alert on deviations

How to Mitigate CVE-2026-29226

Immediate Actions Required

• Upgrade Apache OFBiz to version 24.09.06 or later as published in the Apache Security Mailing List advisory
• Restrict network egress from the OFBiz server to only the destinations required for business operations
• Block the OFBiz host from reaching cloud instance metadata services unless explicitly required
• Review access logs for the Content component for evidence of prior exploitation attempts

Patch Information

Apache has released Apache OFBiz 24.09.06, which remediates the SSRF in the Content component. Administrators should plan an upgrade following the project's standard upgrade procedure. Details are available in the Apache Security Mailing List thread.

Workarounds

• Place the OFBiz Content component endpoints behind a reverse proxy that filters URL parameters and rejects requests targeting internal address ranges
• Apply firewall rules on the OFBiz host to deny outbound traffic to RFC1918 ranges and cloud metadata endpoints
• Limit exposure of OFBiz administrative and Content endpoints to trusted networks via network segmentation or VPN access

# Example iptables rules to block egress to internal and metadata addresses
iptables -A OUTPUT -m owner --uid-owner ofbiz -d 169.254.169.254 -j DROP
iptables -A OUTPUT -m owner --uid-owner ofbiz -d 10.0.0.0/8 -j DROP
iptables -A OUTPUT -m owner --uid-owner ofbiz -d 172.16.0.0/12 -j DROP
iptables -A OUTPUT -m owner --uid-owner ofbiz -d 192.168.0.0/16 -j DROP
