CVE-2026-84889— A path traversal vulnerability in file handling components could allow an authenticated attacker to write files to arbitrary locations on the server filesystem

Quick assessment

Affected
IBM Langflow OSS
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.

IBM Langflow OSS是美国IBM公司的一款可视化构建AI工作流的低代码工具平台。 IBM Langflow OSS 1.0.0版本至1.10.3版本存在路径遍历漏洞，该漏洞源于对受限目录的路径名限制不当，容易受到路径遍历攻击，可能导致远程认证攻击者执行任意代码。
