CVE-2026-31380 Apache Software Foundation CVE debrief

CVE-2026-31380 is an Expression Language Injection issue in Apache OFBiz affecting versions before 24.09.06. The supplied advisory guidance recommends upgrading to 24.09.06, which fixes the flaw. Because expression-language weaknesses can allow attacker-controlled input to be interpreted in server-side expression contexts, this should be treated as a priority security update for affected deployments.

Who should care

Administrators, developers, and security teams running Apache OFBiz, especially deployments that are internet-facing or that process untrusted form, URL, or API input.

Technical summary

The supplied source material maps this vulnerability to CWE-917, Improper Neutralization of Special Elements used in an Expression Language Statement. That class of issue arises when untrusted input is not properly neutralized before it is handled by an expression language evaluator. The affected range is Apache OFBiz versions before 24.09.06; version 24.09.06 is identified as the fixed release.

Defensive priority

High for any exposed Apache OFBiz deployment; plan to patch at the next maintenance window.

Recommended defensive actions

  • Upgrade Apache OFBiz to version 24.09.06 or later.
  • Inventory all OFBiz installations, including test, staging, and bundled instances.
  • Review custom code and integrations for any paths that evaluate or forward user-controlled data into expression language contexts.
  • Strengthen input validation and server-side safeguards around untrusted input paths.
  • Monitor the Apache security reference and NVD entry for any follow-up advisory details or clarifications.
