WordPress < 3.9.5 / 4.1.x < 4.1.4 / 4.2.x < 4.2.1 Comments Stored XSS



The remote server is hosting an outdated installation of WordPress that is affected by a cross-site scripting vulnerability.


Versions of WordPress 3.9.x prior to 3.9.5 , 4.1.x prior to 4.1.4 , and 4.2.x prior to 4.2.1 are affected by an input validation flaw that allows an unauthenticated attacker to inject JavaScript into WordPress comments. This could result in a stored cross-site scripting attack being carried out when the affected comment is later viewed.


Upgrade to WordPress 4.2.1, or later. If 4.2.x cannot be obtained, 4.1.4 was also patched for this vulnerability.\n\nAs a workaround, disable comments and do not approve any comments.
