The implementation of Cross-Origin Resource Sharing (CORS) in WebKit, as used in Apple Safari before 4.0.4 and Google Chrome before 3.0.195.33, includes certain custom HTTP headers in the OPTIONS request during cross-origin operations with preflight, which makes it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks via a crafted web page.

Security readout for executives and security teams

This old WebKit browser flaw made some cross-site request forgery attacks easier. A malicious website could abuse affected Safari or Chrome behavior during CORS preflight requests. The main business risk is from obsolete browsers or embedded WebKit clients still in use. Exposure is most likely where users still run Safari before 4.0.4, Chrome before 3.0.195.33, or legacy WebKit packages referenced by vendors. Modern managed browsers are unlikely to be affected, but embedded or unpatched legacy systems should be checked. Treat as a legacy-technology risk. It is not KEV-listed and affects very old browser versions, but it matters if regulated workflows, kiosks, or embedded systems still depend on outdated WebKit clients. Mitigation focus: Upgrade Safari to 4.0.4 or later where applicable.; Upgrade Google Chrome to 3.0.195.33 or later where applicable.; Check Apple and distribution advisories for applicable WebKit package updates..
