A fix is available — apply it.

Craft CMS versions >= 5.0.0-RC1 before 5.10.6 and >= 4.0.0-RC1 before 4.18.2 contain a theoretical path traversal weakness in the ensurePathIsContained function of the Local file system class. The order of operations validates the path before normalization, so normalization could invalidate prior validation assumptions (a desanitization-style issue) and potentially resolve to files outside the intended volume directory. The vendor notes the issue is not directly exploitable and no exploitable scenario has been discovered; the fix is recommended for hardening.
