Cross-site Scripting in docsify

Description

docsify prior to 4.11.4 is susceptible to Cross-site Scripting (XSS). Docsify.js uses fragment identifiers (parameters after # sign) to load resources from server-side .md files. Due to lack of validation here, it is possible to provide external URLs after the /#/ (domain.com/#//attacker.com) and render arbitrary JavaScript/HTML inside docsify page.

Recommendation

Update the docsify package to the latest compatible version. Followings are version details:

• Affected version(s): < 4.11.4
• Patched version(s): 4.11.4
