Description

Spring Data Commons, versions prior to 1.13 to 1.13.10, 2.0 to 2.0.5, and older unsupported versions, contain a property path parser vulnerability caused by unlimited resource allocation. An unauthenticated remote malicious user (or attacker) can issue requests against Spring Data REST endpoints or endpoints using property path parsing which can cause a denial of service (CPU and memory consumption).

Affected Spring Products and Versions

Spring Data Commons 1.13 to 1.13.10 (Ingalls SR10)
Spring Data REST 2.6 to 2.6.10 (Ingalls SR10)
Spring Data Commons 2.0 to 2.0.5 (Kay SR5)
Spring Data REST 3.0 to 3.0.5 (Kay SR5)
Older unsupported versions are also affected

Mitigation

Users of affected versions should apply the following mitigation:

2.0.x users should upgrade to 2.0.6
1.13.x users should upgrade to 1.13.11
Older versions should upgrade to a supported branch

Releases that have fixed this issue include:

Spring Data REST 2.6.11 (Ingalls SR11)
Spring Data REST 3.0.6 (Kay SR6)

There are no other mitigation steps necessary.

Note that the use of authentication and authorization for endpoints, both of which are provided by Spring Security, limits exposure to this vulnerability to authorized users.
