CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:LSummary
CVE-2025-60538 is a medium-severity Authentication Bypass by Spoofing (CWE-290) vulnerability in Go-Shiori Shiori. Its CVSS base score is 6.5 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 29th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-7 (Unsuccessful Logon Attempts) and AU-2 (Event Logging) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces limits on consecutive unsuccessful login attempts, blocking brute-force authentication bypass on the login page.
Enables monitoring of authentication events to identify repeated failed login attempts indicative of brute force.
Requires logging of logon events so that brute-force attempts against the login page can be recorded and reviewed.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Protecting, conveying, and verifying identity assertions specifically prevents the spoofing that enables authentication bypass.
Requiring authentication of users/services/hardware directly counters spoofing-based bypass when strong methods are used.
Proofing and binding identities reduces spoofing opportunities during enrollment but does not address runtime authentication implementation flaws.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Secure authentication control directly mitigates authentication bypass by spoofing.
Authentication information management directly addresses credential handling that prevents spoofing.
Security testing can detect spoofing vulnerabilities but does not prevent them by itself.
Access control policy reduces spoofing opportunities but does not prescribe authentication mechanisms.
Identity management supports unique identities but does not guarantee resistance to spoofing.
Access rights assignment limits exposure but does not enforce authentication strength.
