No affected components available
Impact
Apps that register custom protocol handlers via protocol.handle() / protocol.registerSchemesAsPrivileged() or modify response headers via webRequest.onHeadersReceived may be vulnerable to HTTP response header injection if attacker-controlled input is reflected into a response header name or value.
An attacker who can influence a header value may be able to inject additional response headers, affecting cookies, content security policy, or cross-origin access controls.
Apps that do not reflect external input into response headers are not affected.
Workarounds
Validate or sanitize any untrusted input before including it in a response header name or value.
Fixed Versions
41.0.340.8.339.8.338.8.6
