Summary

CVE-2023-32071 is a critical-severity Cross-site Scripting (CWE-79) vulnerability in Xwiki Xwiki. Its CVSS base score is 9.0 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 0.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

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 a cross-site scripting vulnerability that permits execution of JavaScript in the security context of any targeted user. The flaw affects all versions from 2.2-milestone-1 through 14.4.7, 14.10.3, and 15.0-milestone releases, and stems from insufficient output encoding when an attacker supplies a crafted URL that references a page containing an attachment.

An authenticated attacker who can create or modify content can craft a URL that, when visited by a victim user, causes the victim's browser to execute attacker-controlled JavaScript under that user's privileges. Successful exploitation can therefore result in full compromise of the victim's account within the wiki, including the ability to read or alter arbitrary content and perform actions on the victim's behalf.

Official patches are available in XWiki 15.0-rc-1, 14.10.4, and 14.14.8. The project advisory and associated commit describe a one-line change to templates/importinline.vm that sanitizes the relevant input; the same modification is provided as the recommended workaround for instances that cannot be upgraded immediately.

EPSS scores for this CVE reached a peak of 0.5748 before receding to the current value of 0.3378, indicating transient but notable post-disclosure interest. No confirmed in-the-wild exploitation campaigns have been reported in the referenced sources.

Vulnerability Data

XWiki Platform is a generic wiki platform. Starting in versions 2.2-milestone-1 and prior to versions 14.4.8, 14.10.4, and 15.0-rc-1, it's possible to execute javascript with the right of any user by leading him to a special URL on the wiki…

targeting a page which contains an attachment. This has been patched in XWiki 15.0-rc-1, 14.10.4, and 14.4.8. The easiest possible workaround is to edit file `<xwiki app>/templates/importinline.vm` and apply the modification described in commit 28905f7f518cc6f21ea61fe37e9e1ed97ef36f01.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SI-15 Information Output Filtering
addresses: CWE-79 CWE-116

Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.

CA-8 Penetration Testing
addresses: CWE-79

Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.

SI-10 Information Input Validation
addresses: CWE-79

Validates web inputs to reject script-related content that could produce XSS.

PR.PS-06 mostly match
blocks

Secure SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).

PR.PS-02 partial match
blocks

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.5.6 only promotes membership in groups to improve knowledge, receive alerts, and share information; it performs no action that stops XSS exploitation (or even the underlying neutralization defect) and is a pure dependency for other controls per the owner's labeling rule.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-116, a class-level weakness, and none of its children carries one either.
