• XML/Ada SEC.XMLADA-0008-v2 AdaCore security advisory

    From Alastair Hogge@[email protected] to comp.lang.ada on Sun Aug 30 10:52:00 2026

    Hello all,

    Regarding the XML/Ada[1] advisory from AdaCore, they mention that the mitigation is to update to 27.0, however I cannot find this branch or release/tag upstream. I emailed info@, and [email protected] for advice
    1 week ago and have not had a response, I am also not sure if those are
    the correct contacts for such queries.

    Does anyone have any idea if 27.0 is pubically avaiable and if there are problems with version mismatches between XML/Ada-27.0, the rest of the GNATColl Stack and GPRbuild, which are at 26.2?

    Me neither. On Github I see commits related to the Gnatcoll Core vulnerabilities that were disclosed around the same time, but for
    XMLada they seem to be withholding any commits made since January.
    If Adacore continue their usual pattern, we can expect a version 27
    sometime in October or November. Until then, I guess your options are
    to dive into the code to find the bug and fix it yourself, or avoid
    processing any untrusted XML data.
    I'd be interested in a patch to apply to the Fedora package, if
    somebody has one.

    Looks like release/27.1 was branched 2 weeks ago: https://github.com/AdaCore/xmlada/branches
