Answer in brief
CVE-2026-115569 records a Low severity (CVSS 3.3) vulnerability in Fallow: Jest and Vitest `projects` entries let an analyzed repository make Fallow read files outside the project root. The current sources do not mark it as known exploited. The current feed maps fallow-rs/fallow (generic), fallow-rs/fallow-cli (generic), fallow-rs/fallow-core (generic), @fallow-cli/fallow-node (generic). Check affected ranges and fixed versions before updating.

CVSS is 3.3. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
