CVE-2026-64798CriticalCVSS 9.1CVE published 22 July 2026Added to mySites.guru 22 July 2026

Regular Labs IP Login (iplogin) <= 6.2.5 - Client-IP Spoofing and Weak Login Key Entropy (account impersonation)

Regular Labs IP Login up to and including 6.2.5. IP Login trusted forwarded client-IP headers without requiring a configured trusted proxy, so an attacker could spoof the IP used for automatic login and impersonate the mapped account (CVE-2026-64797). Persistent URL login keys were also generated with a non-cryptographic random generator with insufficient entropy, making them guessable (CVE-2026-64798). Also affected by CVE-2026-63265. Fixed in the Regular Labs security release of 22 July 2026 (7.0.0).
