  • Disclosed: 08.01.2025
  • Updated: 11.10.2026 12:21

Vendor: The Apache Software Foundation

Versions Affected: Apache OpenMeetings from 2.1.0 before 8.0.0

Description: Default clustering instructions at https://openmeetings.apache.org/Clustering.html  doesn't specify white/black lists for OpenJPA this leads to possible deserialisation of untrusted data. Users are recommended to upgrade to version 8.0.0 and update their startup scripts to include the relevant 'openjpa.serialization.class.blacklist' and 'openjpa.serialization.class.whitelist' configurations as shown in the documentation.
