Security patch

Note

Thank you to community users Kenny Pierce, Cindy Shen, Jeremy Heil, and Chirag Prajapati for helping to bring this issue to our attention!

A regression discovered in releases 2.5 and 2.5.1 that exposes AtoM users to a potential cross-site scripting (XSS) vulnerability was addressed in Release 2.5.2 with patches that resolve the issue. However, since then, additional locations with the same issue have been reported.

This 2.5.3 release includes a global escaping strategy to fix the regression, rather than patching issues locally as they are discovered.

Related issue ticket: #13192 - Reconsider escaping strategy modification when Markdown support is enabled

We encourage all 2.5 users to upgrade as soon as possible. For those who are concerned about this issue but unable to upgrade at this time, disabling Markdown via Admin > Settings > Markdown will also circumvent the issue until upgrading is possible.

Alternatively, users could apply the following commit as a patch to a 2.5.2 installation to resolve the issue in their current installation:

Tip

You can add .patch to the commit URL above to see it in raw form as a patch that can be applied to your instance. Here's one of many online tutorials on how to work with patches using git:

Users may also wish to review the following announcement - thank you to community user Matthew Bruton for bringing this to our attention:

Artefactual has reviewed the report, and AtoM’s configuration does not meet the criteria for this being a security risk. Nevertheless, we recommend that PHP 7.2 users consider upgrading to PHP version 7.2.24 if possible.
