Status: ModifiedMedium (5)—
Severity5Medium · CVSS 2.0
Exploitation probability1.07 %higher than 64% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

Google Chrome 15.0.874.121 and earlier does not prevent capture of data about the times of Same Origin Policy violations during IFRAME loading attempts, which makes it easier for remote attackers to determine whether a document exists in the browser cache via crafted JavaScript code.
