CVE ID :CVE-2026-34527 Published : May 5, 2026, 7:33 p.m. | 52 minutes ago Description :Sandboxie-Plus is an open source sandbox-based isolation software for Windows. In versions 1.17.2 and earlier, SbieIniServer::HashPassword converts a SHA-1 digest to hexadecimal incorrectly. The high nibble of each byte is shifted right by 8 instead of 4, which always produces zero for an 8-bit value. As a result, the stored EditPassword hash only preserves the low nibble of each digest byte, reducing the effective entropy from 160 bits to 80 bits. This is layered on top of an unsalted SHA-1 scheme. The reduced entropy makes leaked or backed-up password hashes materially easier to brute-force. This issue has been fixed in version 1.17.3.
