Spring Data MongoDB contains a SpEL (Spring Expression Language) expression injection vulnerability. The issue occurs during parameter binding when a user-defined repository query method is annotated with @Query and utilizes a capture-all placeholder.

Affected versions: Spring Data MongoDB 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; 3.4.0 through 3.4.19.

Spring Data MongoDB repository query methods annotated with @Query that use regex parameter binding perform insufficient validation of the bound parameter. An attacker can supply a crafted string to break out of the intended regular expression quoting.

Affected versions: Spring Data MongoDB 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; 3.4.0 through 3.4.19.

A Spring Data MongoDB application is vulnerable to SpEL Injection when using @Query or @Aggregation-annotated query methods with SpEL expressions that contain query parameter placeholders for value binding if the input is not sanitized.
