Critical · 9.8 Public exploit CVE-2016-1000027 EUVD-2022-2463GHSA-4wrc-f8pq-fpqp

Pivotal Spring Framework contains unsafe Java deserialization methods

Published Jan 2, 2020 · Updated Oct 7, 2026 · Assigned by mitre

Package: libspring-java Package: org.springframework:spring-web Ecosystem: Debian Ecosystem: Maven

Description

Pivotal Spring Framework through 5.3.16 suffers from a potential remote code execution (RCE) issue if used for Java deserialization of untrusted data. Depending on how the library is implemented within a product, this issue may or not occur, and authentication may be required. NOTE: the vendor's position is that untrusted data is not an intended use case. The product's behavior will not be changed because some users rely on deserialization of trusted data.
