The threat is real and constant. In April 2026, Adobe issued an emergency patch for CVE-2026-34621, a zero-day vulnerability that had been actively exploited in the wild for at least four months prior. This flaw was a type of "prototype pollution" vulnerability, which allowed attackers to embed malicious JavaScript in a PDF. All a victim had to do was open the PDF, and the hidden code could surreptitiously read sensitive files from the victim's computer and send them to an attacker's server. This represents a silent compromise where everything appears normal, but data is being stolen in the background. Patched versions for Windows and macOS were available, and security experts strongly recommended installing them "within hours, not days". This is just one example. Other critical vulnerabilities, such as CVE-2025-54257 (a "Use After Free" flaw with a high severity score), have been found that could lead to arbitrary code execution if left unpatched. Insecure DLL loading vulnerabilities (CVE-2025-64785) have also been discovered, where a remote attacker could place a specially crafted .dll file to execute code on a victim's system.
