CVE-2026-114370— Undertow: undertow: pathresourcemanager safepaths check allows sibling-directory symlink traversal

Quick assessment

Affected
Red Hat Red Hat build of Apache Camel for Spring Boot 4
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Undertow 服务器的 PathResourceManager 组件中发现了一个漏洞。该组件负责从文件系统提供静态文件服务。此问题的根源在于：用于验证符号链接是否指向安全位置的机制，仅检查目标路径是否以特定字符串开头，而未确保该路径与完整的目录名称完全匹配。这可能导致攻击者在某个目录的名称以与授权安全目录相同的字符开头时，访问该安全目录的兄弟目录中的文件。

Vulnerability Title
Undertow: undertow: pathresourcemanager safepaths check allows sibling-directory symlink traversal
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the PathResourceManager component of the Undertow web server. This component is responsible for serving static files from the file system. The issue occurs because the mechanism used to verify if a symbolic link points to a safe location only checks if the target path starts with a specific string, without ensuring it matches a full directory name. This could allow an attacker to access files in a sibling directory if that directorys name starts with the same characters as an authorized safe directory.
