Who should care

Users of MikroORM versions before 6.6.10 and 7.0.6 should be aware of this SQL injection vulnerability and take steps to mitigate it. This includes reviewing and validating user input, implementing prepared statements or parameterized queries, and monitoring for suspicious database activity. Security teams and operators managing Node.js applications using MikroORM should prioritize patching or mitigating this vulnerability.

Technical summary

The MikroORM library, used for object-relational mapping in Node.js applications, is vulnerable to SQL injection attacks in versions prior to 6.6.10 and 7.0.6. This vulnerability arises when the library improperly handles specially crafted objects that are interpreted as raw SQL query fragments. An attacker could exploit this vulnerability to execute malicious SQL queries, potentially leading to data breaches, data corruption, or other security issues. The vulnerability can be mitigated by updating to a patched version of MikroORM, reviewing and validating user input, and implementing secure database practices.

Defensive priority

High

Recommended defensive actions

  • Update MikroORM to version 6.6.10 or 7.0.6 or later
  • Review and validate user input to prevent injection attacks
  • Implement prepared statements or parameterized queries
  • Monitor for suspicious database activity
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
