CVE-2025-66648
`vega-functions` vulnerable to Cross-site Scripting via `setdata` function
7.2
HIGH
CVSS 3.1
EPSS 0.03%
Description
vega-functions provides function implementations for the Vega expression language. Prior to version 6.1.1, for sites that allow users to supply untrusted user input, malicious use of an internal function (not part of the public API) could be used to run unintentional javascript (XSS). This issue is fixed in vega-functions `6.1.1`. There is no workaround besides upgrading. Using `vega.expressionInterpreter` as described in CSP safe mode does not prevent this issue.
