Bug heat

Launchpad helps you to appraise a bug by giving you a calculated measure — called bug heat — of its likely significance. You can see bug heat in bug listings, and also on individual bug pages, as a number next to a flame icon.

Here's how Launchpad calculates the bug heat score:

Attribute Calculation
Private Adds 150 points
Security issue Adds 250 points
Duplicates Adds 6 points per duplicate bug
Affected users Adds 4 points per affected user
Subscribers (incl. subscribers to duplicates) Adds 2 points per subscriber
