Summary

XWiki Pro Macros from 1.13 before 1.14.5 is affected. The excerpt-include macro does not properly escape the included page's title and runs excerpt content with the macro's rights, which allows syntax injection (CWE-95). Any user who can edit a page, even without script or programming rights, can put executable macro syntax in the title or excerpt and cause remote code execution when the page is included. The flaw affects the confidentiality, integrity and availability of the whole XWiki installation.

Description from the CNA

XWiki Remote Macros provides XWiki rendering macros that are useful when migrating content from Confluence. From 1.13 until 1.14.5, the `excerpt-include` macro does not properly escape the included page's title and executes `excerpt` content with the macro's rights. The title handling in `xwiki-pro-macros-ui/src/main/resources/Confluence/Macros/ExcerptInclude.xml` and the rendering of `excerpt` content into XWiki syntax both allow syntax injection. Any user able to edit a page, even without script or programming rights, can supply executable macro syntax in the title or `excerpt` and cause remote code execution when the page is included. This affects confidentiality, integrity and availability of the whole XWiki installation. This issue is fixed in version 1.14.5.
