CVE-2025-51497

Browsing-history disclosure via verbose URL logging

Published Jul 17, 2025 · Updated Jul 24, 2025

Sensitive-data logging in AdGuard for Safari before 1.11.22 allows local users to read visited URLs from macOS general logs. While its Safari plugin is active, the application records every accessed URL verbosely in the shared macOS logging facility rather than keeping that data private. Any unsandboxed process running under a local user can inspect the log and recover browsing history without interacting with Safari.
