Summary

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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of solidtime-io/solidtime published their own advisory on GitHub. Reviewed sources take precedence over it.
