CVE-2026-15226: Insecure Predictable Temp File
The application manually constructs a temporary file name using a predictable pseudo-random generator and opens it. An attacker can predict the sequence of random values, pre-create the expected file, and cause a denial-of-service or a race condition by forcing the O_EXCL file creation to fail. Use os.CreateTemp, os.MkdirTemp, or cryptographic randomness (cr
