In a recent security update, WhatsApp has addressed a spoofing flaw (CVE-2025-30401) that could enable Remote Code Execution (RCE), thereby paving the way for threat actors to exploit this vulnerability and compromise user devices. According to Meta's advisory, this flaw impacts WhatsApp for Windows versions prior to 2.2450.6.
The advisory elucidates that a maliciously crafted mismatch in the file opening handler based on the attachment's filename extension could have caused the recipient to inadvertently execute arbitrary code rather than viewing the attachment when manually opening the attachment inside WhatsApp. This vulnerability presents an appealing opportunity for threat actors, both financially and politically motivated, due to its popularity and the trust users place in it.
The impact of this spoofing flaw cannot be overstated, as it poses a significant risk to user security. The fact that threat actors can exploit this vulnerability without user interaction makes it a zero-day attack, which means that there is no known exploit available prior to its discovery. This also means that the threat actor does not need any prior knowledge of the vulnerability to execute the malicious code.
Furthermore, the value of this vulnerability stems from WhatsApp's massive user base and the potential for covert access to private chats, media, and device-level control. A zero-day vulnerability in WhatsApp can fetch millions of dollars on underground markets due to its severity and the ease with which it can be exploited.
In recent months, WhatsApp has faced criticism for allowing spyware attacks, including a zero-click, zero-day vulnerability that was exploited by Paragon's Graphite spyware to install the spyware on targeted individuals' devices. The company had previously acknowledged this issue and took steps to address it in December 2024 without releasing any client-side updates.
Additionally, Meta experts have linked the hacking campaign targeting journalists and civil society members with the Paragon spyware (aka Graphite) to an Israeli commercial surveillance vendor called Paragon, which was acquired by AE Industrial Partners for $900 million in December 2024. The company had announced that it had discovered and dismantled a malware campaign via WhatsApp that targeted journalists and civil society members with the Paragon spyware.
The impact of this spoofing flaw highlights the importance of regular security updates and the need for companies to prioritize user security. As the use of mobile apps continues to grow, so does the risk of vulnerabilities like this one being exploited by threat actors. It is imperative that companies like WhatsApp take proactive steps to address these vulnerabilities and protect their users from potential attacks.
