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

Quick assessment

Affected
solidtime-io solidtime
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Solidtime 是一款开源的时间追踪应用。在 0.16.0 版本之前，TogglDataImporter::importData() 方法会从上传的 ZIP 导入文件中的 projects.json 读取由攻击者控制的项目 ID 值，并在未进行任何验证的情况下将其拼接到文件系统路径中。由于 Spatie\TemporaryDirectory\TemporaryDirectory::path() 会自动创建缺失的父目录，路径遍历序列可能逃逸出临时沙箱，在任意可写的宿主机路径上创建目录。此外，ImportContr

Vulnerability Title
Solidtime: Path Traversal in Toggl ZIP Data Importer - arbitrary directory creation + filesystem existence oracle
Source: CVE Program / CVE List V5
Vulnerability 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.
