Description Huzaifa S. Sidhpurwala 2016-01-26 04:11:48 UTC
Security researcher musicDespiteEverything previously reported an issue where illegal control characters were stored in as cookie values in violation of RFC6265. While fixing this issue, Mozilla developer Nicholas Hurley realized that the same issue applied to the names of cookies. These characters have now been disallowed in cookie names. This issue could result in incorrect cookie handling by web servers.
