CVE-2026-51907 · Severity: high · CVSS 8.1 · Published 2026-10-02

TaskingAI is an AI service platform that includes a QR code generator plugin for creating QR code images. A path traversal vulnerability in the QR code generator's save_base64_image function allows attackers to write image files to arbitrary locations on the server by manipulating the project_id parameter, potentially overwriting critical system files or deploying malicious content. This could lead to system compromise, data exposure, or denial of service.

## Technical details

The vulnerability exists in plugin/app/service/image_storage.py's save_base64_image function, which constructs file paths by directly concatenating a user-controlled project_id parameter without path normalization or validation. An attacker can inject path traversal sequences (e.g., "../../../escape") via the X-Project-Id header in POST requests to /v1/execute to escape the intended storage boundary and write files to arbitrary filesystem locations. No containment checks, path resolution, or rejection of traversal sequences are performed.
