XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Affected versions of xwiki are subject to code injection in the `since` parameter of the `/xwiki/bin/view/XWiki/Notifications/Code/LegacyNotificationAdministration` endpoint. This provides an XWiki syntax injection attack via the since-parameter, allowing privilege escalation from view to programming rights and subsequent code execution privilege. The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.3, 14.4.8 and 14.10.3. Users are advised to upgrade. • https://github.com/xwiki/xwiki-platform/commit/6d74e2e4aa03d19f0be385ab63ae9e0f0e90a766 https://github.com/xwiki/xwiki-platform/commit/8e7c7f90f2ddaf067cb5b83b181af41513028754#diff-4e13f4ee4a42938bf1201b7ee71ca32edeacba22559daf0bcb89d534e0225949R70 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-jgg7-w2rj-58cj https://jira.xwiki.org/browse/XWIKI-20287 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions a user without script or programming right may edit a user profile (or any other document) with the wiki editor and add groovy script content. Viewing the document after saving it will execute the groovy script in the server context which provides code execution. This vulnerability has been patched in XWiki 15.0-rc-1 and 14.10.3. Users are advised to upgrade. • https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-jgrg-qvpp-9vwr https://jira.xwiki.org/browse/XWIKI-20423 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions of `org.xwiki.platform:xwiki-platform-logging-ui` it is possible to trick a user with programming rights into visiting a constructed url where e.g., by embedding an image with this URL in a document that is viewed by a user with programming rights which will evaluate an expression in the constructed url and execute it. This issue has been addressed in versions 13.10.11, 14.4.7, and 14.10. Users are advised to upgrade.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user with edit rights on a page (e.g., it's own user page), can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping of the section ids in `XWiki.AdminFieldsDisplaySheet`. This page is installed by default. The vulnerability has been patched in XWiki versions 15.0-rc-1, 14.10.1, 14.4.8, and 13.10.11. • https://github.com/xwiki/xwiki-platform/commit/f1e310826a19acdcdecdecdcfe171d21f24d6ede https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-rfh6-mg6h-h668 https://jira.xwiki.org/browse/XWIKI-20261 • CWE-95: Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') •
