Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Versions of xwiki-platform-oldcore from 2.0 before 14.10.7, and from 15.0-rc-1 before 15.2-rc-1, are affected. After an upgrade, old document revisions that still contain a previously fixed vulnerability can be executed, so an attacker with view rights may be able to run code and affect the whole installation. Upgrade to 14.10.7 or 15.2-rc-1; the source does not give a workaround beyond manually deleting old revisions of affected documents, which it notes is hard to do completely.
