EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2023-29515 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 378,156 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Impact
Any user who can create a space can become admin of that space through App Within Minutes. The admin right implies the script right and thus allows JavaScript injection. The vulnerability can be exploited by creating an app in App Within Minutes. If the button should be disabled because the user doesn't have global edit right, the app can also be created by directly opening /xwiki/bin/view/AppWithinMinutes/CreateApplication?wizard=true on the XWiki installation.
Patches
This has been patched in XWiki 13.10.11, 14.4.8, 14.10.1 and 15.0 RC1 by not granting the space admin right if the user doesn't have script right on the space where the app is created. Error message are displayed to warn the user that the app will be broken in this case. Users who became space admin through this vulnerability won't loose the space admin right due to the fix, so it is advised to check if all users who created AWM apps should keep their space admin rights.
Workarounds
The patch can be applied by patching the affected wiki documents, the most important one being AppWithinMinutes.LiveTableEditSheet. Further, the attack can be prevented by denying view access to AppWithinMinutes.LiveTableEditSheet. This only impacts creation and editing of App Within Minutes apps.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-appwithinminutes, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.xwiki.platform:xwiki-platform-appwithinminutes to 4.2-milestone-1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-29515 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2023-29515 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2023-29515. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2023-29515 in your dependencies?
O3 Security finds CVE-2023-29515 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
