Summary

CVE-2024-41947 is a critical-severity Basic XSS (CWE-80) vulnerability in Xwiki Xwiki. Its CVSS base score is 9.0 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Browser Session Hijacking (T1185); ranked in the top 25% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

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 for building applications, contains a cross-site scripting vulnerability tracked as CVE-2024-41947. The flaw allows an attacker to inject and execute JavaScript by deliberately creating an edit conflict against a page being modified by a higher-privileged user, resulting in script execution in that user's browser session and full compromise of the XWiki instance's confidentiality, integrity, and availability. The issue is classified under CWE-79 and CWE-80 and carries a CVSS 3.1 score of 9.0.

An authenticated user with basic editing rights can trigger the attack by forcing a conflict during another user's editing session; the injected JavaScript then runs with the privileges of the targeted higher-rights user, enabling actions such as data exfiltration or privilege escalation across the installation.

The vulnerability has been addressed in the official patches released for XWiki 15.10.8 and 16.3.0RC1, with the fixes documented in the project's GitHub security advisory and corresponding commits that prevent malicious conflict payloads from executing scripts.

The EPSS score remains flat at 0.1301 with no material increase after disclosure.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover missing or incorrect neutralization of script tags through targeted XSS test cases.

SI-10 Information Input Validation good match

Input validation explicitly requires checking and neutralizing untrusted web inputs containing script-related characters before they reach a downstream renderer.

SI-15 Information Output Filtering good match

Output filtering can catch or sanitize unneutralized script content before it is served to users.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles include mandatory output encoding and neutralization of HTML metacharacters to stop injection at the source.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require output encoding and input validation that prevent basic XSS.

PR.PS-02 partial match
prevents

Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development catches unneutralized script tags before release.

A.5.6 Contact with special interest groups partial match
prevents

Knowledge exchange on emerging attack techniques and patches reduces the likelihood that cross-site scripting flaws remain unaddressed in deployed applications.

A.5.7 Threat intelligence partial match
prevents

Operational indicators of compromise for web-application attacks can be incorporated into WAF or input-filtering rules, lowering the likelihood that unsanitized data reaches the browser.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates input validation and output encoding that directly prevent basic XSS.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for neutralization of script-related HTML tags.

A.8.28 Secure coding partial match
prevents

Secure coding standards require proper escaping of <, >, & to block XSS.
