Cross-Site Scripting in htmr

Description

Versions of htmr prior to 0.8.7 are vulnerable to Cross-Site Scripting (XSS). The package uses innerHTML to unescape HTML entities. This may lead to DOM-based XSS through HTML-encoded XSS payloads. This may allow an attacker to execute arbitrary JavaScript in a victim’s browser.

Recommendation

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

• Affected version(s): < 0.8.7
• Patched version(s): 0.8.7
