On February 18, 2011, the bug in issue #2240 was found and fixed. This fix apparently created a MySQL injection vulnerability but was not yet public. The new vulnerability was discovered February 28, 2011. Due to a lack of version control systems for the life of the 3.x series, this vulnerability was assumed to already be public, and a patch was released rather than simply fixing it in the development version only.
Caveat: Since no version control system was in use at the time and internal security patch notes from 3.x were lost in 2015, the current explanation for this patch had to be extrapolated from peripheral data.
