An upstream fix is merged but not yet released — mitigate (WAF / firewall / segmentation) until the release ships, then apply it.

A vulnerability was detected in pkp pkp-lib up to 3.3.0-22/3.4.0-10/3.5.0-4. The affected element is the function _transformPHP of the file classes/xslt/XSLTransformer.php. The manipulation results in xml external entity reference. The attack can be executed remotely. Upgrading to version 3.3.0-23, 3.4.0-11 and 3.5.0-5 is sufficient to fix this issue. The patch is identified as 78c699370ea43ae2784e1c4ace7c947d207f2b47. Upgrading the affected component is advised.
