CWE-24
Path Traversal: '../filedir'
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize ../ sequences that can resolve to a location that is outside of that directory.
Impactr finds and proves whether CWE-24 — or flaws like it — are actually reachable in your own web apps and APIs, with a reproducible exploit as evidence.
