CamScanner Extract Formula

Security checks for vulnerabilities and agentic risk

Overview

This skill does what it says: it uploads a user-selected image to CamScanner to extract formulas, then downloads the processed PNG.

Install only if you are comfortable sending selected images to CamScanner for processing. Avoid using it with sensitive, proprietary, medical, financial, or student records unless you have reviewed and accept CamScanner's privacy and retention terms.

Finding
This step uploads a local image file to a third-party server, which is an external data transmission of potentially sensitive user content. Although the skill discloses the data flow and the transfer is necessary for the feature, it still creates privacy and confidentiality risk if users provide documents containing proprietary or personal information.
