It is recommended to upgrade the affected component. The identifier of this vulnerability is VDB-216204. Patch is: https://github.com/snoyberg/xml/commit/4be1021791dcdee8b164d239433a2043dc0939ea I see that commit has a tag for xml-hamlet-0.5.0.2 and for html-conduit-1.3.2.2. Are both Gentoo packages affected?
I brought this up in the -haskell channel regarding the PR and they said this only affects xml-conduit. Upstream just produces multiple packages from one repository so the tags for those made their way onto the commit.
