CVE-2023-29510
Published: 19 April 2023
Summary
CVE-2023-29510 is a critical-severity Injection (CWE-74) vulnerability in Xwiki Xwiki. Its CVSS base score is 9.9 (Critical).
Operationally, ranked in the top 3.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
XWiki Platform, a generic wiki platform, contains an injection vulnerability tracked as CVE-2023-29510. Any user can create or override translations scoped only to their own account; these translations are rendered without escaping in privileged contexts, enabling remote code execution. The issue is classified under CWE-74 and carries a CVSS 3.1 score of 9.9.
An attacker needs only edit rights on a single document—granted by default on a user’s own profile—to insert a malicious translation. When the translation is later included in server-side rendering, the injected script executes with the privileges of the rendering context, allowing full compromise of confidentiality, integrity, and availability across the instance.
Official advisories and the referenced commits state that the fix, shipped in XWiki 14.10.2 and 15.0 RC1, requires the script right for user-scoped translations. Because regular users no longer receive script right by default starting with 14.10, the attack surface is removed for unprivileged accounts. No other workarounds are documented.
The EPSS score remains flat at 0.3022 with no material increase after disclosure.

Vulnerability details
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In XWiki, every user can add translations that are only applied to the current user. This also allows overriding existing translations. Such translations…

are often included in privileged contexts without any escaping which allows remote code execution for any user who has edit access on at least one document which could be the user's own profile where edit access is enabled by default. A mitigation for this vulnerability is part of XWiki 14.10.2 and XWiki 15.0 RC1: translations with user scope now require script right. This means that regular users cannot exploit this anymore as users don't have script right by default anymore starting with XWiki 14.10. There are no known workarounds apart from upgrading to a patched versions.
