Operationally, exploitation aligns with the MITRE ATT&CK technique JavaScript (T1059.007); ranked in the top 39% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
XWiki Platform, a generic wiki platform, contains an improper input sanitization flaw in the default-installed XWiki.AdminFieldsDisplaySheet component. The issue stems from inadequate escaping of section identifiers, which permits any user possessing edit rights on a page to inject and execute arbitrary Groovy, Python, or Velocity code, resulting in complete control over the XWiki installation. The vulnerability is tracked as CVE-2023-29511 with a CVSS score of 9.9 and is associated with CWE-95.
An authenticated attacker with page edit permissions, such as on their own user page, can exploit the flaw to run server-side scripts that bypass intended access controls and achieve full system compromise, including data exfiltration or modification. No special user interaction or advanced network positioning is required beyond standard edit access.
Official advisories and patches recommend upgrading to XWiki versions 15.0-rc-1, 14.10.1, 14.4.8, or 13.10.11, where the escaping logic in AdminFieldsDisplaySheet has been corrected; the fixes are detailed in the referenced GitHub commits and security advisory GHSA-rfh6-mg6h-h668. The EPSS score has remained flat at its peak value of 0.2925 with no material increase observed after disclosure.

Security testing in development can detect eval injection vulnerabilities before deployment.
Secure development life cycle mandates input validation and safe coding practices that directly prevent eval injection.
Application security requirements include rules against dynamic code execution of untrusted input.
Secure architecture principles discourage unsafe dynamic evaluation constructs.
Secure coding explicitly requires neutralization of input before dynamic evaluation, directly mitigating eval injection.
