Subject: CVE-2021-26291: Apache Maven: block repositories using http by default
Subject: CVE-2021-26291: Apache Maven: block repositories using http by default
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
This issue is being tracked as MNG-7118
Credit:
Apache Maven would like to thank Jonathan Leitschuh for highlighting
the need for this change.
