Fallow: A `.*` glob segment let an analyzed repository make Fallow test paths in the parent of the project root

影響: npm:fallow < 3.34.0 → 3.34.0, npm:@fallow-cli/fallow-node < 3.34.0 → 3.34.0, rust:fallow-cli < 3.34.0 → 3.34.0, rust:fallow-config < 3.34.0 → 3.34.0, rust:fallow-core < 3.34.0 → 3.34.0

The glob crate tests .. against a segment that starts with a literal .. Fallow validates plugin glob patterns and refuses absolute paths and .. segments, but these segments passed that validation. The attacker controls the repository content. The attacker must also be able to read the Fallow output, for example a CI log or a pull request…
