Detailsinfo

A vulnerability was found in Vmware Spring Data REST up to 3.7.19/4.3.16/4.4.14/4.5.11/5.0.5. It has been classified as critical. This affects an unknown function of the component SpEL Expression Handler. The manipulation with an unknown input leads to a expression language injection vulnerability. CWE is classifying the issue as CWE-917. The product constructs all or part of an expression language (EL) statement in a framework such as a Java Server Page (JSP) using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended EL statement before it is executed. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Spring Data REST is vulnerable to SpEL expression injection through map-typed properties when processing JSON Patch (application/json-patch+json) requests. When a persistent entity exposes a Map-typed property, the JSON Pointer path segment used as the map key is embedded directly into a SpEL expression without sanitization or validation. Affected versions: Spring Data REST 3.7.0 through 3.7.19; 4.3.0 through 4.3.16; 4.4.0 through 4.4.14; 4.5.0 through 4.5.11; 5.0.0 through 5.0.5.

The advisory is shared at spring.io. This vulnerability is uniquely identified as CVE-2026-41729 since 04/22/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 06/10/2026).

Upgrading to version 3.7.20, 4.3.17, 4.4.15, 4.5.12 or 5.0.6 eliminates this vulnerability.
