Critical RCE Exploits Exposed: Apache OFBiz Patches Severe Authentication Bypass Flaws

The Apache OFBiz project has released a critical security update to patch several important vulnerabilities affecting its popular open-source business application suite. Flexible enough to span various industries, Apache OFBiz uses a common architecture designed to let developers easily extend and enhance custom features.

The updates address multiple high-severity bugs—including authentication bypasses, cookie manipulation, and remote code execution (RCE) flaws—affecting all versions of the software prior to 24.09.06. Users are strongly recommended to upgrade to version 24.09.06 immediately to fully secure their environments.

The most severe flaw addressed in this cycle involves an improper authentication vulnerability (CVE-2026-45434) tied directly to the platform’s password-reset functions. A logic flaw within the password-change routine allows an attacker to bypass authentication controls entirely. In vulnerable environments, a successful exploit can be escalated to achieve full Remote Code Execution (RCE) on the server, giving attackers a direct gateway to the host system.

Another entry point for remote code execution was uncovered in the platform’s input validation layers. Due to an improper input validation vulnerability (CVE-2026-31378), attackers can manipulate standard input structures to override JSON attributes. This manipulation allows them to bypass internal URL allowlist protections, allowing the application to process unauthorized instructions and ultimately leading to RCE.

A separate improper authentication bug (CVE-2026-31387) allows threat actors to tamper with browser cookies. By leveraging this cookie manipulation vulnerability, an authenticated attacker can successfully forge JSON Web Tokens (JWT). This token forgery allows malicious users to orchestrate account impersonation attacks, potentially taking over higher-privileged or administrative user sessions across the business application.

A flaw (CVE-2026-29207) involving improper neutralization of special elements within the system’s template engine exposes the platform’s Content Component. Low-privilege users can exploit this Server-Side Template Injection (SSTI) vulnerability to execute arbitrary code on the server context.

To eliminate this risk vector entirely, the Apache OFBiz development team has introduced permanent structural restrictions in the updated software:

• Deprecation of FTL Templates: In version 24.09.06, “Data Resource” records containing a dataTemplateTypeId = “FTL” (FreeMarker Template Language) are no longer supported by the system.
• Privilege Reduction: The default “Ecommerce Customer” security group has been completely stripped of its content management grants.

To secure production systems and business pipelines, administrators must upgrade to Apache OFBiz 24.09.06 or later at their earliest opportunity.
