CVSS 3.1
4.8 mediumCVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:N/I:H/A:NCVE-2026-40986
Medium (4.8) in broadcom spring web flow. EPSS 0.2% chance of exploitation in the next 30 days. Fixed in org.springframework.webflow:spring-webflow 3.0.2, 4.0.1.
Spring Web Flow's JavaScript RemotingHandler renders the body of an error response as HTML even when the response is not "text/html", which can result in a scripting attack in the user's browser if the error response from the server contains error details with input reflected from an attacker.
Affected versions:
Spring Web Flow 4.0.0; 3.0.0 through 3.0.1; 2.5.0 through 2.5.1.
