{"cve":"CVE-2025-26619","nvd":{"published":"2025-03-27T14:15:52.987","modified":"2026-06-17T09:02:08.527","status":"Analyzed","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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","score":5.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://github.com/vega/vega-lite/issues/9469","https://github.com/vega/vega/commit/8fc129a6f8a11e96449c4ac0f63de0e5bfc7254c","https://github.com/vega/vega/issues/3984","https://github.com/vega/vega/security/advisories/GHSA-rcw3-wmx7-cphr","https://github.com/vega/vega/security/advisories/GHSA-rcw3-wmx7-cphr"],"products":["vega-functions_project:vega-functions","vega_project:vega"],"source":"nvd","synced_at":"2026-10-19T22:00:28.034033815+00:00"},"epss":{"cve":"CVE-2025-26619","score":0.00354,"percentile":0.29112,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-rcw3-wmx7-cphr","url":"https://osv.dev/vulnerability/GHSA-rcw3-wmx7-cphr","summary":"Vega Cross-Site Scripting (XSS) via event filter when not using CSP mode expressionInterpeter","modified":"2026-09-10T03:50:23.273639008Z","packages":[{"ecosystem":"npm","name":"vega","purl":"pkg:npm/vega","ranges":["<5.31.0"],"fixed":["5.31.0"]},{"ecosystem":"npm","name":"vega-functions","purl":"pkg:npm/vega-functions","ranges":["<5.16.0"],"fixed":["5.16.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
