Researchers Find Critical Zero-Day Vulnerabilities in Foxit and Apryse PDF Platforms  PDF files are often seen as simple digital documents, but recent research shows they have evolved into complex software environments that can expose corporate systems to cyber risks. Modern PDF tools now function more like application platforms than basic viewers, potentially giving attackers pathways into private networks.  A study by Novee Security examined two widely used platforms, Foxit and Apryse. Released on February 18, 2026, the report identified 13 categories of vulnerabilities and 16 potential attack paths that could allow systems to be compromised.  Researchers say these issues are more than minor bugs. Some zero-day flaws could allow attackers to run commands on backend servers or take over user accounts without needing to compromise a browser or operating system. To find the vulnerabilities, analysts first identified common patterns that signal security weaknesses. These patterns were then used to train an AI system that scanned large volumes of code much faster than manual review alone.  By combining human insight with automated analysis, the system detected several high-impact issues that conventional scanning tools might miss. One major flaw appeared in Foxit’s digital signature server, which verifies electronically signed documents. Some of the most serious findings involve one-click exploits where simply opening a document or loading a link can trigger malicious activity. Vulnerabilities CVE-2025-70402 and CVE-2025-70400 affect Apryse WebViewer by allowing the software to trust remote configuration files without proper validation, enabling attackers to run malicious scripts.  Another flaw, CVE-2025-70401, showed that malicious code could be hidden in the “Author” field of a PDF comment and executed when a user interacts with it. Researchers also identified CVE-2025-66500, which affects Foxit browser plugins. In this case, manipulated messages could trick the plugin into running harmful scripts within the application. Testing further showed that certain weaknesses could allow attackers to send a simple request that triggers command execution on a server, granting unauthorized access to parts of the system.  These vulnerabilities highlight how small interactions or overlooked behaviors can lead to significant security risks. Experts say the core problem lies in how modern PDF platforms are built. Many now rely on web technologies such as iframes and server-side processing, yet organizations still treat PDF files as harmless static documents. This mismatch can create “trust boundary” failures where software accepts external data without sufficient validation.  Both vendors were notified before the research was published, and the vulnerabilities were assigned official CVE identifiers to support patching efforts. The findings highlight how document-processing systems—often overlooked in security planning—can become complex attack surfaces if not properly secured.
