GHSA-2fxf-qj94-3f83
MEDIUMGHSA-2fxf-qj94-3f83 is a medium-severity (CVSS 6.1) Cross-site Scripting (XSS) vulnerability in org.apache.jspwiki:jspwiki-main. O3 Security confirms whether GHSA-2fxf-qj94-3f83 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Apache JSPWiki XSS due to crafted request on XHRHtml2Markup.jsp
Blast Radius
org.apache.jspwiki:jspwiki-mainReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
A carefully crafted request on XHRHtml2Markup.jsp could trigger an XSS vulnerability on Apache JSPWiki up to and including 2.11.2, which could allow the attacker to execute javascript in the victim's browser and get some sensitive information about the victim. Version 2.11.3 contains a fix for the problem
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.jspwiki:jspwiki-main. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update org.apache.jspwiki:jspwiki-main to 2.11.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2fxf-qj94-3f83 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-2fxf-qj94-3f83 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-2fxf-qj94-3f83. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
