CVE-2026-31069
Deferred Deferred - Pending Action
SQL Injection in BillaBear Prior to Jan 2026

Publication date: 2026-05-19

Last updated on: 2026-05-20

Assigner: MITRE

Description
BillaBear (all versions prior to Jan 2026) contains a SQL Injection vulnerability in the EventRepository. User-controlled input from metric filter names and aggregation properties is directly interpolated into SQL queries using sprintf() without proper sanitization or identifier quoting. Although filter values are parameterized, the filter identifiers (keys) are not. An authenticated attacker with ROLE_ACCOUNT_MANAGER permissions can exploit this to execute arbitrary SQL commands.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Compliance Impact

The vulnerability is a SQL Injection in BillaBear that allows an authenticated attacker with specific permissions to execute arbitrary SQL commands. Such vulnerabilities can lead to unauthorized access or manipulation of sensitive data.

While the provided context does not explicitly mention compliance impacts, SQL Injection vulnerabilities generally pose risks to data confidentiality and integrity, which are critical concerns under standards like GDPR and HIPAA.

Exploitation of this vulnerability could potentially result in data breaches or unauthorized data exposure, thereby affecting compliance with regulations that mandate protection of personal and health information.

Executive Summary

CVE-2026-31069 is a SQL Injection vulnerability found in BillaBear versions prior to January 2026. The issue exists in the EventRepository component where user-controlled input from metric filter names and aggregation properties is directly inserted into SQL queries using sprintf() without proper sanitization or quoting of identifiers.

While the filter values themselves are parameterized, the filter identifiers (keys) are not, which allows an authenticated attacker with ROLE_ACCOUNT_MANAGER permissions to exploit this flaw and execute arbitrary SQL commands on the database.

Impact Analysis

This vulnerability can allow an attacker with certain authenticated permissions to execute arbitrary SQL commands on the backend database. This can lead to unauthorized data access, data modification, or deletion.

Such exploitation could compromise the integrity and confidentiality of your data, potentially leading to data breaches, loss of sensitive information, or disruption of service.

Mitigation Strategies

The vulnerability is caused by improper sanitization of user-controlled input in SQL queries within BillaBear versions prior to January 2026. Immediate mitigation steps include:

  • Restrict access to users with ROLE_ACCOUNT_MANAGER permissions to trusted personnel only.
  • Apply any available patches or updates from BillaBear that address this SQL Injection vulnerability.
  • Review and sanitize all user inputs, especially metric filter names and aggregation properties, to prevent direct interpolation into SQL queries.
  • Implement proper parameterization and identifier quoting in SQL queries to avoid injection.
  • Monitor logs for suspicious SQL activity or unauthorized access attempts.
