CVE-2026-92709 concerns rsyslog's omfile dynaFile facility when a dynamic file-path template incorporates untrusted input as a path component without secure path handling. Crafted input can cause the rendered output path to traverse outside the administrator-intended logging directory. The available information does not identify affected rsyslog versions, a vulnerable function, or a vendor-fixed release.

An important rsyslog omfile dynaFile path-traversal/file-write issue. In explicitly deployed configurations where an attacker can influence a value used as a dynaFile path component, rsyslog may create or append to files outside the intended log directory, constrained by its effective privileges, filesystem permissions, mandatory access controls, and sandboxing. Code execution requires additional deployment-specific conditions and is not representative of default configurations.
