Security Vulnerabilities in SheetJS Dependency (xlsx npm package)

Hi !

While reviewing our dependency tree, we noticed that Zerox's use of SheetJS (xlsx) may be affected by two known high-severity vulnerabilities reported recently:

Regular Expression Denial of Service (ReDoS)

• Detected in: xlsx (npm)

Prototype Pollution

• Detected in: xlsx (npm)

Both vulnerabilities are rated High in various advisories.

Do you know if the project currently pins or depends on a vulnerable version of xlsx, and whether an update or mitigation is already planned or in progress?

Thank you in advance !
