Description Thibault Guittet 2026-08-20 07:17:14 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

The PackagerResolver of Apache Ivy is able to download online
artifacts and to (re)package them in a format defined by a
packager.xml file. This repackaging is done by an Ant script, which is
stored in a subdirectory of the configured "buildRoot" directory. This
subdirectory is calculated based on modules coordinates, like the
organisation, name or version.

If one of the coordinates contains "../" sequences - which are valid
characters for Ivy coordinates in general- it is possible to break out
of the configured "buildRoot" directory where other files can be
overwritten.

In order to exploit this vulnerability an attacker needs to have
access to a packager repository and add or modify the coordinates in
ivy.xml files to have such "../" sequences.

Users of Apache Ivy 2.0.0 to 2.5.3 (inclusive) should upgrade to Ivy 2.6.0.

Comment 1 Filipe Rosset 2026-08-20 20:41:27 UTC
Ivy 2.6.0 is already in rawhide / F45, should we backport it to F44 and F43 too ?

full changelog is here: https://ant.apache.org/ivy/history/2.6.0/release-notes.html

Comment 2 Thibault Guittet 2026-08-21 12:55:49 UTC
Yes, that would fix the vulnerability ;)

(In reply to Thibault Guittet from comment #2)
> Yes, that would fix the vulnerability ;)

I mean, let me check if the upgrade will cause some regressions or not... thanks.
