Jun Zhu found that some profile fields were vulnerable to Cross-Site Request Forgery (CSRF). An attacker could use these flaws to perform actions on profiles (such as deleting categories). These issues affected Moodle versions 2.6, 2.5 to 2.5.4, 2.4 to 2.4.7, 2.3 to 2.3.10 and earlier unsupported versions. It has been fixed in 2.6.1, 2.5.4, 2.4.8 and 2.3.11. I have not checked if versions 1.9.19 in EPEL 5 is affected or not. Patch: http://git.moodle.org/gw?p=moodle.git&a=search&h=HEAD&st=commit&s=MDL-42883
