{"id":"CVE-2023-26487","summary":"Vega has cross-site scripting vulnerability in `lassoAppend` function","details":"Vega is a visualization grammar, a declarative format for creating, saving, and sharing interactive visualization designs.`lassoAppend' function accepts 3 arguments and internally invokes `push` function on the 1st argument specifying array consisting of 2nd and 3rd arguments as `push` call argument. 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","aliases":["GHSA-w5m3-xh75-mp55"],"modified":"2026-08-12T03:51:08.767108781Z","published":"2023-03-03T23:47:28.486Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/26xxx/CVE-2023-26487.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-79"]},"references":[{"type":"WEB","url":"https://github.com/vega/vega/releases/tag/v5.23.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/26xxx/CVE-2023-26487.json"},{"type":"ADVISORY","url":"https://github.com/vega/vega/security/advisories/GHSA-w5m3-xh75-mp55"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-26487"},{"type":"FIX","url":"https://github.com/vega/vega/commit/01adb034f24727d3bb321bbbb6696a7f4cd91689"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/vega/vega","events":[{"introduced":"0"},{"fixed":"fb1092f6b931d450f9c210b67ae4752bd3dd461b"},{"fixed":"01adb034f24727d3bb321bbbb6696a7f4cd91689"}],"database_specific":{"cpe":"cpe:2.3:a:vega_project:vega:*:*:*:*:*:node.js:*:*","extracted_events":[{"introduced":"0"},{"fixed":"5.23.0"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v5.22.1","v5.22.0","v5.21.0","v5.20.1","v5.20.2","v5.20.0","v5.19.1","v5.19.0","v5.18.0","v5.17.3","v5.17.2","v5.17.1","v5.17.0","v5.16.1","v5.16.0","v5.15.0","v5.14.0","v5.13.0","v5.12.3","v5.12.2","v5.12.1","v5.12.0","v5.11.1","v5.11.0","v5.10.1","v5.10.0","v5.9.2","v5.9.1","v5.9.0","v5.8.1","v5.8.0","v5.7.3","v5.7.2","v5.7.1","v5.7.0","v5.6.0","v5.5.3","v5.5.2","v5.5.1","v5.5.0","v5.4.1","v4.5.1","v5.4.0","v5.3.5","v5.3.4","v5.3.3","v5.3.2","v5.3.1","v5.3.0","v5.2.0","v5.1.0","v5.0.0","v5.0.0-rc5","v5.0.0-rc4","v5.0.0-rc3","v5.0.0-rc2","v5.0.0-rc1","v4.4.0","v4.3.0","v4.2.0","v4.1.0","v4.0.0","v4.0.0-rc.3","v4.0.0-rc.1","v3.3.1","v3.3.0","v3.2.1","v3.2.0","v3.1.0","v3.0.10","v3.0.9","v3.0.8","v3.0.7","v3.0.6","v3.0.5","v3.0.4","v3.0.3","v3.0.2","v3.0.1","v3.0.0","v3.0.0-rc7","v3.0.0-rc6","v3.0.0-rc5","v3.0.0-rc4","v3.0.0-rc3","v3.0.0-rc2","v3.0.0-rc1","v3.0.0-beta.39","v3.0.0-beta.38","v3.0.0-beta.37","v3.0.0-beta.36","v3.0.0-beta.35","v3.0.0-beta.34","v3.0.0-beta.33","v3.0.0-beta.32","v3.0.0-beta.31","v3.0.0-beta.30","v3.0.0-beta.29","v3.0.0-beta.28","v3.0.0-beta.27","v3.0.0-beta.26","v3.0.0-beta.25","v3.0.0-beta.24","v3.0.0-beta.23","v3.0.0-beta.22","v3.0.0-beta.21","v3.0.0-beta.20","v3.0.0-beta.19","v3.0.0-beta.18","v3.0.0-beta.17","v3.0.0-beta.16","v3.0.0-beta.15","v3.0.0-beta.14","v3.0.0-beta.13","v3.0.0-beta.12","v3.0.0-beta.11","v3.0.0-beta.10","v3.0.0-beta.8","v3.0.0-beta.7","v3.0.0-beta.6","v3.0.0-beta.4","v3.0.0-beta.3","v3.0.0-beta.2","v1.5.4","v1.5.1","v1.5.0","v1.4.3","v1.4.2","v1.4.1","v1.4.0","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.0","v1.1.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-26487.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}
