Actually, FreeMarker does block java.security.ProtectionDomain.getClassLoader *since 2.3.30*, released in 2020-03-05, not just since 2.3.31. So even 2.3.30 is safe from this particular CVE. I'm also discussing this with Veracode, and they did answer, so we will see if they will update their database.
And yet again, if that CVE was a real problem for you, then you certainly have much more problems there: https://freemarker.apache.org/docs/app_faq.html#faq_template_uploading_security On Wed, Mar 9, 2022 at 4:16 PM Demarcq, Arnaud <arnaud.dema...@experian.com> wrote: > Hi @Daniel Dekany <daniel.dek...@gmail.com>, > > > > Thanks for the confirmation. > > > > Kind regards, > > > > Arnaud > > > > *From:* Daniel Dekany <daniel.dek...@gmail.com> > *Sent:* Wednesday, March 9, 2022 4:13 PM > *To:* Demarcq, Arnaud <arnaud.dema...@experian.com> > *Cc:* FreeMarker developer list <dev@freemarker.apache.org>; EMA > Development <ema-developm...@experian.com> > *Subject:* Re: [EXTERNAL] Re: CVE-2021-46361 in freemarker lib > > > > Yes, if the problem is what they have linked, then you are safe with > 2.3.31.
