CVE-2025-15560 is a high-severity SQL Injection (CWE-89) vulnerability in Nestersoft Worktime. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 16.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2025-15560 is a SQL injection vulnerability (CWE-89) in the WorkTime server's "widget" API endpoint, affecting instances configured with either a Firebird or MSSQL database backend. Published on 2026-02-19, it has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant confidentiality, integrity, and availability impacts.
An authenticated attacker with minimal permissions can exploit the vulnerability over the network with low complexity and no user interaction required. When using the Firebird backend, the attacker can retrieve all data from the database. With the MSSQL backend, the attacker can execute arbitrary SQL statements on the database, enabling access to sensitive data.

Mitigating Controls (NIST 800-53 r5) AI
Directly prevents SQL injection by validating and sanitizing inputs to the vulnerable widget API endpoint before they reach the database backend.
Requires identification, reporting, and patching of the specific SQL injection flaw in the WorkTime server to eliminate the vulnerability.
Enforces least privilege on the application's database service account, limiting the scope of data access or arbitrary SQL execution even if injection succeeds.
