CVE-2025-26619 Information

Description

Vega is a visualization grammar a declarative format for creating saving and sharing interactive visualization designs. In vega 5.30.0 and lower and in vega-functions 5.15.0 and lower it was possible to call JavaScript functions from the Vega expression language that were not meant to be supported. The issue is patched in vega 5.31.0 and vega-functions 5.16.0. Some workarounds are available. Run vega without vega.expressionInterpreter. This mode is not the default as it is slower. Alternatively using the interpreter described in CSP safe mode (Content Security Policy) prevents arbitrary Javascript from running so users of this mode are not affected by this vulnerability.
