CVSS calls it medium at 6.1. It is confirmed in active exploitation. It sits in the 99.2th percentile for exploit probability.
⚠️ A crafty little flaw lurks in Roundcube's email handling! When it processes text/plain messages, attackers can slip in malicious links that lead unsuspecting users to harmful sites. 😱 Think of it like a restaurant that serves food with hidden ingredients — you’re expecting a delicious meal, but someone sneaks in something nasty that ruins the whole experience! An attacker could exploit this vulnerability to execute malicious scripts in the user's browser, potentially leading to data theft or compromised accounts. It's like inviting a wolf in sheep's clothing to your dinner party, where they can wreak havoc without the guests noticing!
