CWE-36
Absolute Path Traversal
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize absolute path sequences such as /abs/path that can resolve to a location that is outside of that directory.
Impactr finds and proves whether CWE-36 — or flaws like it — are actually reachable in your own web apps and APIs, with a reproducible exploit as evidence.
