CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:XSummary
CVE-2026-26341 is a critical-severity Use of Default Credentials (CWE-1392) vulnerability in Tattile Smart\+ Firmware. Its CVSS base score is 9.3 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Default Accounts (T1078.001); ranked in the top 16% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to CM-6 (Configuration Settings) and IA-5 (Authenticator Management) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-26341 affects the firmware of Tattile Smart+, Vega, and Basic device families in versions 1.181.5 and prior. These devices ship with default credentials that are not forced to be changed during installation or commissioning, exposing the management interface to authentication using those unchanged credentials.
An attacker who can reach the management interface over the network can exploit this vulnerability with no required privileges, low attack complexity, and no user interaction. Successful exploitation grants administrative access, enabling unauthorized modification of device configuration and access to sensitive data. The issue carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and maps to CWE-1392.

V13.2.1
Mitigating Controls (NIST 800-53 r5) AI
Secure configuration settings establish baselines that prohibit default credentials on system components.
Authenticator management requires verification of identity and secure distribution of initial authenticators, directly stopping default credentials from being left in place.
Vulnerability scanning can discover default credentials after deployment but does not stop their introduction.
Account management processes include assignment and control of initial account credentials, reducing the chance defaults remain active.
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.
Hardened baselines and configuration management explicitly prohibit default credentials on deployed systems.
Credential management processes directly require replacing or disabling default passwords and keys.
Authentication policies can enforce non-default credential strength but do not explicitly address initial deployment defaults.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
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.
The requirement to replace vendor default authentication information immediately after installation directly counters the use of default credentials that attackers commonly target.
