Summary

CVE-2022-36098 is a high-severity Cross-site Scripting (CWE-79) vulnerability in Xwiki Xwiki. Its CVSS base score is 8.9 (High).

Operationally, ranked in the top 0.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-15 (Information Output Filtering) — see the control section below for these in your framework.

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 Mentions UI, a component of the generic wiki platform XWiki, contains a stored cross-site scripting vulnerability (CWE-79) in versions starting with 12.5-rc-1 and prior to 13.10.6 and 14.4. Malicious JavaScript or Groovy code can be persisted in mention, macro anchor, or reference fields and is later executed in the context of any user who views the affected page.

An authenticated attacker with low privileges can insert the scripts through normal mention functionality; because the payload executes for other visitors, the attacker can achieve confidentiality, integrity, and limited availability impacts across the application, consistent with the CVSS 8.9 rating that reflects network attack vector, required user interaction, and changed scope.

The GitHub Security Advisory and linked commits describe the official fixes released in XWiki 13.10.6 and 14.4. As a workaround, administrators can edit the Macro code field of the XWiki.WikiMacroClass XObject inside XWiki.Mentions.MentionsMacro to neutralize script execution.

The EPSS score remains at 0.4365 with no material increase after disclosure.

Vulnerability Data

XWiki Platform Mentions UI is a user interface for mentioning users in wiki content for XWiki Platform, a generic wiki platform. Starting in version 12.5-rc-1 and prior to versions 13.10.6 and 14.4, it's possible to store Javascript or groovy scripts…

in a mention, macro anchor, or reference field. The stored code is executed by anyone visiting the page with the mention. This issue has been patched on XWiki 14.4 and 13.10.6. As a workaround, one may update `XWiki.Mentions.MentionsMacro` and edit the `Macro code` field of the `XWiki.WikiMacroClass` XObject.

prevent

Validates mention/macro/reference fields to reject or sanitize JavaScript/Groovy payloads before they are persisted.

prevent

Filters or escapes script content on output when rendering pages containing stored mentions, blocking execution for viewers.

preventdetect

Can detect and block malicious script code introduced via the mentions feature before it reaches other users.

PR.PS-06 mostly match

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).

detects

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

prevents

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

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.

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.

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.

none

Webpage malware scanning and block-listing of known malicious sites reduce the likelihood that reflected or stored script payloads reach a user’s browser.
