Summary

The core.urlresolvers.reverse function in Django before 1.4.14, 1.5.x before 1.5.9, 1.6.x before 1.6.6, and 1.7 before release candidate 3 does not properly validate URLs, which allows remote attackers to conduct phishing attacks via a // (slash slash) in a URL, which triggers a scheme-relative URL to be generated.

Fencer Intel 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.
