AI-suggested

Upgrade to LiquidJS version 10.26.0 or later, where this issue is fixed. Until then, avoid relying solely on the strip_html filter for XSS protection and ensure that output escaping is enabled when rendering untrusted input. Patch status is not explicitly stated but the fix is available in version 10.26.0.

Description

LiquidJS versions 10.25.7 and below contain a cross-site scripting (XSS) vulnerability in the strip_html filter. The filter fails to remove HTML tags containing newline characters due to a regex limitation, allowing malicious tags with embedded event handlers to bypass sanitization. This can lead to script execution when attacker-controlled input is rendered without additional HTML escaping. The issue is fixed in version 10.26.0.
