Title
Incomplete protection against CVE-2025-11226
Summary
Path-traversal vulnerability in QOS.CH Sarl Logback-classic on Java (logback-classic module) allows path-traversal vulnerability. More specifically, an
MDC-based discriminator value flows unsanitized into a nested
FileAppender path, letting an attacker who influences that MDC value
(e.g. via an HTTP header)
create and append log files outside the intended directory.
This issue affects Logback-classic: from 0.9.14 through 1.6.2.
