Cross-site scripting (XSS) vulnerability in the Ephox (formerly Moxiecode) plupload.flash.swf shim 2.1.2 in Plupload, as used in WordPress 3.9.x, 4.0.x, and 4.1.x before 4.1.2 and other products, allows remote attackers to execute same-origin JavaScript functions via the target parameter, as demonstrated by executing a certain click function, related to _init.as and _fireEvent.as.

Security readout for executives and security teams

This is a legacy cross-site scripting issue in the Flash upload component used by Plupload. In affected WordPress versions before 4.1.2, an attacker could cause same-site JavaScript behavior through the vulnerable shim. The main business risk is older public websites still running outdated WordPress or bundled Plupload code. Exposure is most likely on legacy WordPress installations before 4.1.2 or other products that bundled Plupload 2.1.2 with the Flash SWF shim reachable from the web. Treat as a cleanup priority for internet-facing legacy web estates. It is old and not KEV-listed, but affected systems likely indicate broader patch hygiene problems. Mitigation focus: Upgrade WordPress installations to 4.1.2 or later where applicable.; Apply relevant Debian or Fedora package security updates if using distro packages.; Inventory other applications bundling Plupload 2.1.2 and check vendor guidance..
