Liferay Portal and DXP, which are open source web content management and collaboration platforms, were found to have a vulnerability that could allow remote code execution.

The issue arises because by default, these platforms do not sanitize HTML or JavaScript entered into blog posts. A malicious actor could craft a blog post containing malicious code and have it run when other users view the blog. This is known as a cross-site scripting (XSS) attack.

XSS attacks work by injecting client-side scripts into web pages viewed by other users. The scripts can then access data, cookies, and perform actions across the affected sites. This could allow an attacker to hijack user sessions, deface websites, or redirect users to malicious sites.

To protect yourself, Liferay has released fixes for this issue. Users should ensure they update their Liferay Portal or DXP installations to the latest versions to apply the security patches. It is also recommended to sanitize any untrusted inputs to prevent XSS.

Always be cautious of any unverified or untrusted content on websites. Only interact with trusted sources and keep your software up to date. Taking these basic steps can help prevent many common web vulnerabilities and attacks.
