The advisory warns that attackers could use various techniques to exploit vulnerabilities in Mozilla Firefox and Thunderbird. One method involves disguising harmful downloads with misleading filenames which makes it difficult for users to tell them apart from safe files. Attackers might also use clickjacking to trick users into interacting with dangerous content.

Moreover, specially crafted WebTransport requests could lead to denial-of-service (DoS) attacks. Most concerning are memory safety bugs that could let attackers execute malicious code, potentially taking full control of affected systems.
