CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-29506 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Xwiki Xwiki. Its CVSS base score is 5.4 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 23% 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 Commons, the technical libraries shared across multiple XWiki projects, contain a cross-site scripting vulnerability tracked as CVE-2023-29506 and CWE-79. The flaw allows code injection through the URLs of authenticated endpoints and was addressed in the releases XWiki 13.10.11, 14.4.7, and 14.10.
An unauthenticated remote attacker can exploit the issue by supplying a crafted URL that triggers script execution when a victim interacts with it. Successful exploitation yields limited impacts on confidentiality and integrity, consistent with the CVSS 5.4 rating that requires user interaction but no prior authentication.
Public advisories and patches published via the XWiki Jira tracker and GitHub Security Advisories GHSA-jjm5-5v9v-7hx2 document the affected code paths and the commits that restrict URL handling to prevent injection.
EPSS scores for the CVE rose from lower values to a peak of 0.4132 on 2025-12-11 before receding to the current 0.1150, indicating a period of increased exploitation interest 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.
