CVE-2026-14180— Undertow 输入验证错误漏洞
一分钟漏洞结论
影响对象
Red Hat Red Hat JBoss Enterprise Application Platform 8.1 for RHEL 10
利用判断
尚无明确在野利用证据，仍需结合暴露面评估
建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
Undertow是美国Undertow组织开源的一个Web服务器。 Undertow存在输入验证错误漏洞，该漏洞源于ChunkReader组件中的解析器使用单个内部变量存储剩余块大小和状态标志，攻击者通过发送特制请求的超大块大小导致这些值重叠，诱使解析器误认为请求已提前完成，可能导致第二个“夹带”请求被不同步处理，从而绕过安全控制。

Vulnerability Title
Undertow-core: undertow:http request smuggling via oversized chunk-size bit overlap
来源: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the ChunkReader component of the Undertow HTTP server, which is used by WildFly and JBoss EAP to handle chunked transfer encoding. The issue occurs because the parser uses a single internal variable to store both the remaining chunk size and state flags. By sending a specially crafted request with an extremely large chunk size, an attacker can cause these values to overlap, tricking the parser into thinking a request has finished prematurely. This can allow a second, "smuggled" request to be processed out of sync, potentially bypassing security controls.
