An iFrame, or inline frame, is a component within a webpage that allows for the embedding of another HTML document.
This secondary document can also include JavaScript and/or CSS, which are executed when the user’s browser processes the iframe tag. WordPress users frequently encounter iframes when attempting to incorporate content from external sources into their sites.
A well-known example of iframe embed code is the one used for YouTube videos, which appears as follows: In this example, the iframe tag initiates the loading of YouTube’s video player using the specified video ID.
Additionally, it includes various attributes such as height, width, and frameborder, which are utilized by the script to display the YouTube player correctly. Many third-party platforms provide users with iframe embed codes to integrate specific elements into their websites, including web analytics services, social media platforms, and video sharing sites.
Important Note: Users should exercise caution when embedding iframe codes into their websites. It is crucial to ensure that the source of the iframe code is trustworthy and that you are familiar with the website’s identity.
Cybercriminals may exploit vulnerabilities by inserting iframe code into WordPress sites as a means to establish a backdoor, allowing them remote access to compromised sites.
