CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:LCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-26480 is a high-severity Cross-site Scripting (CWE-79) vulnerability in Xwiki Xwiki. Its CVSS base score is 8.9 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 49% 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 a stored cross-site scripting vulnerability in the Live Data macro that affects all versions starting from 12.10. The flaw is tracked as CWE-79 and carries a CVSS 3.1 score of 8.9, reflecting network-accessible attack vectors with low complexity and low privileges required.
An authenticated user lacking script rights can persist malicious script payloads via the macro, enabling execution in other users' browsers with the potential for high impact on confidentiality, integrity, and availability under the reflected scope change.
Public references, including the GitHub security advisory GHSA-32fq-m2q5-h83g and the linked XWiki Jira ticket XWIKI-20143, state that the issue is resolved in releases 14.9, 14.4.7, and 13.10.10; the associated commits detail the code changes that enforce proper escaping. No workarounds are documented.
The EPSS score remains flat at 0.0855 with no material increase after disclosure.

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.
Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.
Validates web inputs to reject script-related content that could produce XSS.
Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
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).
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).
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
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.
