Summary

CVE-2025-47945 is a critical-severity Insecure Default Variable Initialization (CWE-453) vulnerability in Donetick Donetick. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Default Accounts (T1078.001); ranked at the 47th percentile by exploit likelihood (below the median); 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-2 (Baseline Configuration) and CM-6 (Configuration Settings) — see the control section below for these in your framework.

Vulnerability Data

Donetick an open-source app for managing tasks and chores. Prior to version 0.1.44, the application uses JSON Web Tokens (JWT) for authentication, but the signing secret has a weak default value. While the responsibility is left to the system administrator…

Mitigating Controls (NIST 800-53 r5) AI

CM-6 Configuration Settings good match

Requires establishing the most restrictive configuration settings, which directly overrides or prevents use of insecure default variable initializations.

CM-2 Baseline Configuration good match

Requires maintaining a documented baseline configuration that can enforce secure initial values instead of insecure defaults.

AC-6 Least Privilege partial match

Least privilege reduces the blast radius of any insecure default permissions that remain after initialization.

SA-8 Security and Privacy Engineering Principles partial match

Mandates application of security engineering principles during development that include use of secure defaults and proper variable initialization.

PR.PS-01 full match
prevents

Hardened baselines and configuration management directly replace insecure defaults with secure settings.

PR.PS-06 mostly match
prevents

Secure software development practices explicitly include choosing safe initial values instead of insecure defaults.

ID.RA-09 partial match
prevents

Pre-acquisition integrity checks can reject products known to ship with insecure defaults.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect insecure defaults but does not prevent them.

A.8.9 Configuration management mostly match
prevents

Configuration management enforces secure default values and prevents insecure initialization.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle requires explicit secure initialization of variables.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles include avoiding insecure defaults in design.

A.8.28 Secure coding partial match
prevents

Secure coding standards mandate explicit, safe variable initialization.

A.8.32 Change management partial match
prevents

Requiring documented specification, testing, and acceptance of changes ensures that new or modified components are not initialized with insecure default settings that would otherwise be left in production.
