# CVE-2026-76806: Solidtime: Path Traversal in Toggl ZIP Data Importer - arbitrary directory creation + filesystem existence oracle

Status: published. Published: 2026-11-04. Updated: 2026-11-04.

Solidtime is an open-source time-tracking app. Prior to 0.16.0, TogglDataImporter::importData() read attacker-controlled project id values from projects.json in uploaded ZIP imports and concatenated them into filesystem paths without validation. Because Spatie\TemporaryDirectory\TemporaryDirectory::path() creates missing parent directories, traversal sequences could escape the temporary sandbox and create directories at arbitrary writable host paths. Distinguishable ImportController responses for existing versus missing targets exposed whether suffix-constrained host paths derived from projects_users/{id}.json or tasks/{id}.json existed, because the importer always appended .json. Any registered user able to create an organization and use POST /api/v1/organizations/{org}/import with type=toggl_data_importer could reach the flaw, potentially causing minor availability impact through directory exhaustion and disclosing host layout information. This issue is fixed in version 0.16.0.
