Who should care

Developers and administrators using Spring Data MongoDB versions 5.0.0 through 5.0.5, 4.5.0 through 4.5.11, 4.4.0 through 4.4.14, 4.3.0 through 4.3.16, 4.2.0 through 4.2.15, 4.1.0 through 4.1.14, 4.0.0 through 4.0.15, and 3.4.0 through 3.4.19 should be aware of this vulnerability and take necessary actions to mitigate it.

Technical summary

The vulnerability is caused by the lack of proper input validation in Spring Data MongoDB's parameter binding process. When a user-defined repository query method is annotated with @Query and uses a capture-all placeholder, an attacker can inject malicious SpEL expressions, potentially leading to arbitrary code execution.

Defensive priority

HIGH

Recommended defensive actions

  • Upgrade to a patched version of Spring Data MongoDB.
  • Review and update user-defined repository query methods to prevent SpEL expression injection.
