CVE-2026-39915
HighCVSS 8.1Summary
TIM Flow before 26.0.6 contains a CRLF injection vulnerability that allows remote attackers to inject arbitrary HTTP headers and response body content by embedding unsanitized carriage return and line feed sequences in the rt URL parameter, which is reflected into Set-Cookie response headers. Attackers can craft malicious requests to induce authenticated users to execute arbitrary JavaScript in their browser context, enabling session token theft and account credential modification.
Risk Assessment
CRLF injection can lead to session hijacking, credential theft, and account modification, posing a serious threat to application security and user data.
Recommendation
Update TIM Flow to version 26.0.6 or later, which includes a fix for neutralizing CRLF sequences in the rt parameter.
