  "details": "### Summary\nThe excerpt-include macro does not properly escape the title of the included page and executes the content of the excerpt with the macro\u0027s rights. Therefore, it is vulnerable to XWiki syntax injection via the included page\u0027s title and content, allowing remote code execution for any user who can edit a page.\n\n### Details\nThe title of the included page isn\u0027t escaped in [ExcerptInclude.xml#L277](https://github.com/xwikisas/xwiki-pro-macros/blob/main/xwiki-pro-macros-ui/src/main/resources/Confluence/Macros/ExcerptInclude.xml#L277). Further, the content of the excerpt macro is rendered to XWiki syntax and output into the macro\u0027s content such that it is executed with the macro\u0027s rights.\n\n### PoC\n1. As a user without script or programming right, create a page named `Exploit`.\n2. In the edit screen, change the title to `{{async}}{{groovy}}println(\"Hello from Groovy Title!\"){{/groovy}}{{/async}}`.\n3. Set the content to\n```\n{{excerpt-include 0=\"Exploit.WebHome\"}}{{/excerpt-include}}\n\n{{excerpt}}\n  {{async}}{{groovy}}println(\"Hello from Groovy content!\"){{/groovy}}{{/async}}\n{{/excerpt}}\n```\n4. Save and view the page.\n5. If this displays \"Hello from Groovy Title!\" without the surrounding macro code or \"Hello from Groovy content!\", the attack succeeded.\n\n### Impact\nRemote code execution impacts the confidentiality, integrity and availability of the whole XWiki installation.",
