Details

Cross-Site Scripting in lazysizes Versions of `lazysizes` prior to 5.2.1-rc1 are vulnerable to Cross-Site Scripting. The `video-embed` plugin fails to sanitize the following attributes: data-vimeo, `data-vimeoparams`, `data-youtube` and `data-ytparams`. This allows attackers to execute arbitrary JavaScript in a victim's browser if the attacker has control over the vulnerable attributes. ## Recommendation Upgrade to version 5.2.1-rc1 or later.
