CWE-30
Path Traversal: 'dir..filename'
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize 'dir..filename' (leading backslash dot dot) sequences that can resolve to a location that is outside of that directory.
Impactr finds and proves whether CWE-30 — or flaws like it — are actually reachable in your own web apps and APIs, with a reproducible exploit as evidence.
