The type of the 1st argument is supposed to be an array, but it's not enforced. This makes it possible to specify any object with a `push` function as the 1st argument, `push` function can be set to any function that can be access via `event.view` (no all such functions can be exploited due to invalid context or signature, but some can, e.g. `console.log`). The issue is that`lassoAppend` doesn't enforce proper types of its arguments. This issue opens various XSS vectors, but exact impact and severity depends on the environment (e.g. Core JS `setImmediate` polyfill basically allows `eval`-like functionality). This issue was patched in 5.23.0.\n"}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"vega","product":"vega","versions":[{"version":"< 5.23.0","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":2.5},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","baseScore":6.1,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"CHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":2.7}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2025-02-25T14:31:39.665748Z","id":"CVE-2023-26487","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-79"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:vega-functions_project:vega-functions:*:*:*:*:*:node.js:*:*","versionEndExcluding":"5.13.1","matchCriteriaId":"573B200A-A938-460B-8B95-3F4E2B98E15A"},{"vulnerable":true,"criteria":"cpe:2.3:a:vega_project:vega:*:*:*:*:*:node.js:*:*","versionEndExcluding":"5.23.0","matchCriteriaId":"FDAFA09A-097A-45DB-9E8F-B8ED261D0550"}]}]}],"references":[{"url":"https://github.com/vega/vega/commit/01adb034f24727d3bb321bbbb6696a7f4cd91689","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/vega/vega/releases/tag/v5.23.0","source":"security-advisories@github.com","tags":["Release Notes"]},{"url":"https://github.com/vega/vega/security/advisories/GHSA-w5m3-xh75-mp55","source":"security-advisories@github.com","tags":["Exploit","Third Party Advisory"]},{"url":"https://github.com/vega/vega/commit/01adb034f24727d3bb321bbbb6696a7f4cd91689","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://github.com/vega/vega/releases/tag/v5.23.0","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Release Notes"]},{"url":"https://github.com/vega/vega/security/advisories/GHSA-w5m3-xh75-mp55","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Exploit","Third Party Advisory"]}]}}]}
