Code execution via mismatched ZIP filename headers
Published Jul 25, 2025 · Updated May 14, 2026
Filename spoofing in RARLAB WinRAR 3.80 before 3.91 and 4.11 before 5.00 allows attackers to execute code via crafted ZIP files. WinRAR displays the Central Directory filename but extracts and opens the Local File Header filename without requiring the two names to match. Exploitation requires a user to open the archive and launch the apparently harmless entry, which runs the substituted payload with that user's access.
