CVE-2026-25880 is a high-severity vulnerability in SumatraPDF versions 3.5.2 and earlier, involving an untrusted search path weakness (CWE-426). When a user opens a PDF and clicks File → “Show in folder”, the application executes a binary named explorer.exe located in the same directory as the PDF without proper validation. This allows an attacker to place a malicious executable in the PDF’s folder, leading to arbitrary code execution with the current user's privileges. Exploitation requires user interaction limited to clicking the menu option, with no additional warnings. The vulnerability affects Windows systems running vulnerable SumatraPDF versions. Although no known exploits are reported in the wild yet, the ease of exploitation and high impact on confidentiality, integrity, and availability make this a significant threat. European organizations using SumatraPDF on Windows should prioritize patching or mitigating this issue to prevent potential compromise.
