Summary

CVE-2022-36097 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 Browser Session Hijacking (T1185); ranked in the top 1.0% 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 Attachment UI, a component of the generic wiki platform XWiki, contains a stored cross-site scripting vulnerability. Versions from 14.0-rc-1 up to but not including 14.4-rc-1 allow JavaScript to be persisted in an attachment filename; the script executes in the browser of any user who later attempts to move that attachment. The flaw is tracked under CWE-79 and CWE-80 and carries a CVSS 3.1 score of 8.9.

An authenticated user with attachment-creation privileges can upload a file whose name contains executable script. When another user with move rights opens the move dialog for that attachment, the script runs with the victim’s session privileges, enabling theft of sensitive data, account takeover, or other actions within the wiki’s security context.

The project’s security advisory and the associated patch commit state that the issue is fixed in XWiki 14.4-rc-1. Administrators unable to upgrade immediately are advised to copy the template moveStep1.vm into the web application directory and replace the vulnerable code with the version supplied in the patch.

EPSS for the CVE rose from a low baseline after disclosure to a peak of 0.4419 on 2025-12-11 before receding to the current value of 0.2183, indicating a clear increase in observed exploitation interest well after the original publication date.

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.

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.

SI-15 Information Output Filtering
addresses: CWE-79

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

PR.PS-06 mostly match
prevents

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
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).

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.8.29 Security testing in development and acceptance mostly match
finds

Secure-coding testing and automated code-analysis tools are applied to detect improper neutralization of script-related content during web-page generation.

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

Requiring language-specific secure-coding standards and automated scanning during the SDLC catches missing output encoding or improper neutralization of untrusted data before the software reaches production.

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, SAST scans and removal of insecure code samples together eliminate the failure to neutralize script content that produces cross-site scripting flaws.
