CVE-2026-31906 Apache Software Foundation CVE debrief

Apache OFBiz contains a reflected cross-site scripting (XSS) vulnerability due to improper neutralization of input during web page generation. The flaw affects all versions prior to 24.09.06. An attacker can exploit this by crafting a malicious URL that, when visited by an authenticated or unauthenticated user, executes arbitrary JavaScript in the victim's browser context. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) indicates network attack vector, low complexity, no privileges required, user interaction required, changed scope, and low impacts to confidentiality and integrity with no availability impact. Apache released version 24.09.06 on May 19, 2026 to remediate this issue. No known exploitation in the wild or ransomware campaign use has been reported.
