CVE-2026-115569

Fallow is a codebase intelligence tool for TypeScript and JavaScript. From 2.68.0 until 3.34.0, Fallow follows attacker-controlled Jest projects paths outside the project root through absolute paths, parent segments, dot-prefixed wildcard globs, or symlinks. In version 3.33.1, the same behavior also affects Vitest test.projects paths, Vitest inline-project extends paths, and symlinked script --config paths. Fallow parses the outside files as test-runner configuration and uses them to credit dependencies, setup files, and JSX import sources, which can change unused dependency and unused file findings in CI or agent analysis. The outside file contents are not printed or sent over the network. This issue is fixed in version 3.34.0.
