Critical · 9.1 Public exploit CVE-2021-26291 BIT-maven-2021-26291EUVD-2021-1241GHSA-2f88-5hg8-9x2x

block repositories using http by default

Published Apr 23, 2021 · Updated Aug 3, 2024 · Assigned by apache

Vendor: Apache Software Foundation Product: Apache Maven Package: maven Package: maven Package: org.apache.maven:maven-compat Package: org.apache.maven:maven-core Ecosystem: Debian Ecosystem: Maven Ecosystem: Ubuntu

Description

Apache Maven will follow repositories that are defined in a dependency’s Project Object Model (pom) which may be surprising to some users, resulting in potential risk if a malicious actor takes over that repository or is able to insert themselves into a position to pretend to be that repository. Maven is changing the default behavior in 3.8.1+ to no longer follow http (non-SSL) repository references by default. More details available in the referenced urls. If you are currently using a repository manager to govern the repositories used by your builds, you are unaffected by the risks present in the legacy behavior, and are unaffected by this vulnerability and change to default behavior. See this link for more information about repository management: https://maven.apache.org/repository-management.html
