Summary

LiveConnect in Mozilla Firefox before 2.0.0.13 and SeaMonkey before 1.1.9 does not properly parse the content origin for jar: URIs before sending them to the Java plugin, which allows remote attackers to access arbitrary ports on the local machine. NOTE: this is closely related to CVE-2008-1195.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
