⚠️ A prototype pollution vulnerability hides in stealjs 2.2.4, lurking in the optionName variable like a misfiled record in an archive! Think of this as a library where someone could sneak a book onto the shelf that alters the entire catalog — suddenly, a classic could become a horror novel with the wrong twist! If exploited, this vulnerability could lead to unexpected changes in object structures, causing chaos in applications that rely on them. It’s not a full-blown disaster yet, but if you’re using this version, it’s a sneaky concern that might come back to haunt you!
