CVE-2026-111388: Frappe restrict_ip Bypass Vulnerability

Sources read

Source agreement

Tam uyum

Evidence confidence

%55

Short explanation

Frappe Framework does not enforce the per-user restrict_ip allowlist for non-session authentication methods such as API key and OAuth. This allows individuals with valid credentials to authenticate from IP addresses outside the allowlist, bypassing configured network-based access restrictions [S0].

Why does it matter?

Bypassing network-based access restrictions causes configured IP security controls to fail, enabling access to systems from unauthorized locations [S0].

What should be done?

Monitor vendor advisories for update guidance [S0]
Update affected versions where possible [S0]

Chain of evidence and sources2 verified claims

Frappe Framework, 15.120.0 ve 16.33.0 öncesi sürümlerde oturum dışı kimlik doğrulama yöntemleri için restrict_ip beyaz listesini zorunlu kılmamaktadır [S0].

Show the technical text from the sources

Frappe Framework before 15.120.0 and 16.x before 16.33.0 does not enforce the per-user restrict_ip allowlist for non-session authentication methods, including API key, OAuth, and header-based authentication. Attackers holding valid credentials of these types can authenticate from IP addresses outside the allowlist, defeating the configured network-based access restrictions.
