CVE-2007-5038: Mozilla Bugzilla

High severity, CVSS 7.5. EPSS: 2% chance of exploitation in the next 30 days.

The offer_account_by_email function in User.pm in the WebService for Bugzilla before 3.0.2, and 3.1.x before 3.1.2, does not check the value of the createemailregexp parameter, which allows remote attackers to bypass intended restrictions on account creation.

Affected products
