The former. The CVE-2010-1104 issue was applicable to Zope3 too (just wasn't described in the description). The reason probably being the CVE-2010-1104 to had been reported against Zope2 version only (according to particular LaunchPad bug). Zope2 patch for CVE-2010-1104 was incomplete (still allowing XSS). Not sure, if there was some Zope3 patch for CVE-2010-1104 applied. Jan-Wijbrand Kolman could you clarify and help us to understand original CVE-2010-1104 situation in Zope3?
