Spring Framework 6.1.x < 6.1.29 / 6.2.x < 6.2.20 / 7.0.x < 7.0.8.1 maxPartSize Ignored in PartEventHttpMessageReader

high Nessus Plugin ID 341187

Synopsis

The Spring Framework install on the remote host is affected by a resource exhaustion vulnerability.

Description

The version of Spring Framework installed on the remote host is 6.1.x prior to 6.1.29, 6.2.x prior to 6.2.20, or 7.0.x prior to 7.0.8.1. It is, therefore, affected by a vulnerability:

- The PartEventHttpMessageReader in Spring WebFlux does not enforce the maxPartSize limit when maxInMemorySize is set to -1. PartEventHttpMessageReader is used when a controller method has an @RequestBody Flux<PartEvent> argument.
(CVE-2026-47885)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Spring Framework version 6.1.29 / 6.2.20 / 7.0.8.1 / 7.0.9 or later. Note that some fixed releases are available to Enterprise Support customers only; refer to the vendor advisory for details.
