Description Jon Moroney 2026-06-29 22:17:21 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.

CSS::Minifier::XS versions before 0.14 for Perl have a memory leak when the entire document is minified away.

The minify function has a memory leak when processing a document containing only characters to be removed, such as comments and whitespace.
