Machine-written summary

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

The xwiki-platform-lesscss-script Maven package, in versions from 6.1-milestone-1 up to 15.10.12, from 16.0.0-rc-1 up to 16.4.3, and from 16.5.0-rc-1 up to 16.8.0-rc-1, lets a user clear the LESS compiler cache without programming right because the script API checks rights incorrectly. An attacker needs script right, which already allows unrestricted script execution, so the added impact is limited to slowing XWiki while caches refill. Upgrade to 15.10.12, 16.4.3, or 16.8.0-rc-1. No other workaround is known beyond limiting script right to trusted users.
