Stored XSS in TimelineJS3

In TimelineJS before version 3.7.0, some user data renders as HTML. An attacker could implement an XSS exploit with maliciously crafted content in a number of data fields. This risk is present whether the source data for the timeline is stored on Google Sheets or in a JSON configuration file. Most TimelineJS users configure their timeline with a Google Sheets document. Those users are exposed to this vulnerability if they grant write access to the document to a malicious inside attacker, if the access of a trusted user is compromised, or if they grant public write access to the document. Some TimelineJS users configure their timeline with a JSON document. Those users are exposed to this vulnerability if they grant write access to the document to a malicious inside attacker, if the access of a trusted user is compromised, or if write access to the system hosting that document is otherwise compromised. Version 3.7.0 of TimelineJS addresses this in two ways. For content which is intended to support limited HTML markup for styling and linking, that content is "sanitized" before being added to the DOM. For content intended for simple text display, all markup is stripped. Very few users of TimelineJS actually install the TimelineJS code on their server. Most users publish a timeline using a URL hosted on systems we control. The fix for this issue is published to our system such that **those users will automatically begin using the new code**. The only exception would be users who have deliberately edited the embed URL to "pin" their timeline to an earlier version of the code. Some users of TimelineJS use it as a part of a wordpress plugin (knight-lab-timelinejs). Version 3.7.0.0 of that plugin and newer integrate the updated code. Users are encouraged to update the plugin rather than manually update the embedded version of TimelineJS.

TimelineJS 跨站脚本漏洞

TimelineJS是美国西北大学骑士实验室（Northwestern University Knight Lab）的一款用于构建交互式时间轴的开源工具。 TimelineJS 3.7.0之前版本中存在跨站脚本漏洞，该漏洞源于程序没有正确验证用户输入。远程攻击者可利用该漏洞获取用户的身份验证凭据。
