CVSS 10.0 CriticalCriticalEPSS 0.35 · 98th percentile

Critical, because:

  • CVSS score 10.0: 9.0 or more.
  • CVSS score 10.0 (7.0 or more) and EPSS 0.35 (0.1 or more): a high score and a real chance of exploitation in the next 30 days.

Machine-written summary

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

XWiki Platform's xwiki-platform-search-ui package is vulnerable to remote code execution through the database search text in versions from 2.4-milestone-1 before 14.10.20, from 15.0-rc-1 before 15.5.4, and from 15.6-rc-1 before 15.10-rc-1. An attacker needs no account, since the database search is accessible to any visitor by default, and can run code on the whole XWiki installation. Upgrade to 14.10.20, 15.5.4, 15.10-rc-1 or later. Alternatively, if database search is not used, the Main.DatabaseSearch page can be deleted.
