CVE-2005-2263: Mozilla Firefox

Medium severity, CVSS 5.0. EPSS: 3.1% chance of exploitation in the next 30 days.

The InstallTrigger.install method in Firefox before 1.0.5 and Mozilla before 1.7.9 allows remote attackers to execute a callback function in the context of another domain by forcing a page navigation after the install method has been called, which causes the callback to be run in the context of the new page and results in a same origin violation.
