Synopsis

The Spring Framework install on the remote host is affected by multiple vulnerabilities.

Description

The version of Spring Framework installed on the remote host is 5.3.x prior to 5.3.49, 6.1.x prior to 6.1.28, 6.2.x prior to 6.2.18.1, or 7.0.x prior to 7.0.7.1. It is, therefore, affected by multiple vulnerabilities:

- IDs for WebSocket sessions in the spring-websocket module are not cryptographically unpredictable, which may be possible to exploit in combination with inadequate authorization rules. (CVE-2026-41838)

- Applications may be vulnerable to a Regular Expression Denial of Service (ReDoS) attack if an attacker is able to provide a pattern which is then directly or indirectly supplied to one of the following methods in AntPathMatcher:
match, matchStart, extractUriTemplateVariables. (CVE-2026-41848)

- In an untrusted JMS environment, org.springframework.jms.support.converter.MappingJackson2MessageConverter and org.springframework.jms.support.converter.JacksonJsonMessageConverter allow arbitrary class instantiation, which can lead to unauthorized actions via gadget class deserialization. (CVE-2026-41855)

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

Solution

Upgrade to Spring Framework version 5.3.49, 6.1.28, 6.2.18.1, or 7.0.7.1 or later.
