Spring Data MongoDB Injection Vulnerabilities

Remote code execution risk in Spring Data MongoDB arises from a SpEL expression injection flaw (CWE-917) triggered during parameter binding for repository methods annotated with @Query that use a capture-all placeholder. With CVSS 8.1 (AV:N/AC:H/PR:N/UI:N) and no public exploit identified at time of analysis, unauthenticated attackers who can influence query parameters reaching such a method could execute arbitrary SpEL expressions on the server.

Regex parameter binding in Spring Data MongoDB's @Query annotation fails to sufficiently quote user-supplied strings, enabling NoSQL injection that can manipulate query semantics. Unauthenticated remote attackers (PR:N, AV:N) who can influence the bound parameter in applications using this pattern may break out of the intended regular expression context to retrieve unintended documents, resulting in high-impact confidentiality compromise. No confirmed active exploitation or public exploit code has been identified at time of analysis; the CVSS Attack Complexity of High reflects a dependency on a specific application-level coding pattern.
