Google Chrome before 4.0.211.0 cannot properly restrict modifications to cookies established in HTTPS sessions, which allows man-in-the-middle attackers to overwrite or delete arbitrary cookies via a Set-Cookie header in an HTTP response, related to lack of the HTTP Strict Transport Security (HSTS) includeSubDomains feature, aka a "cookie forcing" issue.

Google Chrome, when the Invisible Hand extension is enabled, uses cookies during background HTTP requests in a possibly unexpected manner, which might allow remote web servers to identify specific persons and their product searches via HTTP request logging, related to a "cross-site data leakage" issue.

Unspecified vulnerability in Google Chrome before 4.1.249.1036 allows remote attackers to truncate the URL shown in the HTTP Basic Authentication dialog via unknown vectors.

The protocolIs function in platform/KURLGoogle.cpp in WebCore in WebKit before r55822, as used in Google Chrome before 4.1.249.1036 and Flock Browser 3.x before 3.0.0.4112, does not properly handle whitespace at the beginning of a URL, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a crafted javascript: URL, as demonstrated by a \x00javascript:alert sequence.
