Therefore it was possible for users of legacy, pre-2017 browsers who navigate to a page serving `fides.js` to download and execute malicious scripts from the `polyfill.io` domain when the domain was compromised and serving malware. No exploitation of `fides.js` via `polyfill.io` has been identified as of time of publication.\n\nThe vulnerability has been patched in Fides version `2.39.1`. Users are advised to upgrade to this version or later to secure their systems against this threat. On Thursday, June 27, 2024, Cloudflare and Namecheap intervened at a domain level to ensure `polyfill.io` and its subdomains could not resolve to the compromised service, rendering this vulnerability unexploitable. Prior to the domain level intervention, there were no server-side workarounds and the confidentiality, integrity, and availability impacts of this vulnerability were high. Clients could ensure they were not affected by using a modern browser that supported the fetch standard."}],"source":{"advisory":"GHSA-cvw4-c69g-7v7m","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-07-02T20:11:37.728266Z","id":"CVE-2024-38537","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-07-02T20:11:44.703Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T04:12:24.976Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/ethyca/fides/security/advisories/GHSA-cvw4-c69g-7v7m","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/ethyca/fides/security/advisories/GHSA-cvw4-c69g-7v7m"},{"name":"https://github.com/ethyca/fides/pull/5026","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/ethyca/fides/pull/5026"},{"name":"https://github.com/ethyca/fides/commit/868c4d629760572192bd61db34f5a4458ed12005","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/ethyca/fides/commit/868c4d629760572192bd61db34f5a4458ed12005"},{"name":"https://fetch.spec.whatwg.org","tags":["x_refsource_MISC","x_transferred"],"url":"https://fetch.spec.whatwg.org"},{"name":"https://sansec.io/research/polyfill-supply-chain-attack","tags":["x_refsource_MISC","x_transferred"],"url":"https://sansec.io/research/polyfill-supply-chain-attack"}]}]}}
