{"id":"CVE-2026-44179","published":"2026-10-28T16:17:07.400","lastModified":"2026-10-28T16:17:07.400","description":"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.","cvssScore":9.9,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","cwes":["CWE-95"],"vendors":[],"products":[],"references":[{"url":"https://github.com/xwikisas/xwiki-pro-macros/commit/151d4fccb62f6ec5f3c972e837869454677ab1ca","tags":[]},{"url":"https://github.com/xwikisas/xwiki-pro-macros/releases/tag/xwiki-pro-macros-1.14.5","tags":[]},{"url":"https://github.com/xwikisas/xwiki-pro-macros/security/advisories/GHSA-w56x-9778-rppx","tags":[]}],"exploitRefs":[{"url":"https://github.com/xwikisas/xwiki-pro-macros/commit/151d4fccb62f6ec5f3c972e837869454677ab1ca","tags":[]},{"url":"https://github.com/xwikisas/xwiki-pro-macros/releases/tag/xwiki-pro-macros-1.14.5","tags":[]},{"url":"https://github.com/xwikisas/xwiki-pro-macros/security/advisories/GHSA-w56x-9778-rppx","tags":[]}],"hasPoc":true,"ai":{"summary":"The `excerpt-include` macro in XWiki Remote Macros versions 1.13 through 1.14.4 allows unauthenticated syntax injection via the included page's title and excerpt content, leading to remote code execution when a page is rendered, due to insufficient escaping and unsafe macro execution with the macro's privileges.","exploitability":"Exploitation requires only basic edit permissions on a page (no script or programming rights) and knowledge of how to inject malicious macro syntax into the title or excerpt content.","blast_radius":"Successful exploitation grants full compromise of confidentiality, integrity, and availability across the entire XWiki installation, as the macro executes with its own elevated privileges.","remediation":"Upgrade to XWiki Remote Macros version 1.14.5 or later, which patches the vulnerability in the `excerpt-include` macro.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","macro-injection","xwiki","syntax-injection","confluence-migration"],"model":"garnet-coder","analyzedAt":"2026-10-29T08:40:41.543Z"}}
