- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
Exploitation and automatability from CISA’s SSVC triage for GHSA-gg53-wf5x-r3r6.
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
GHSA-gg53-wf5x-r3r6 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 377,238 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.
Real-World Exposure
org.xwiki.platform:xwiki-platform-security☕org.xwiki.platform:xwiki-platform-security☕org.xwiki.platform:xwiki-platform-securityReal-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
Impact
A bug in the security cache is storing rules associated to document Page1.Page2 and space Page1.Page2 in the same cache entry.
That means that it's possible to overwrite the rights of a space or a document by creating the page of the space with the same name and checking the right of the new one first so that they end up in the security cache and are used for the other too.
Patches
The problem has been patched in XWiki 12.10.11, 13.10.1, 13.4.6.
Workarounds
No workaround other than patching.

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-security, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.xwiki.platform:xwiki-platform-security to 12.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gg53-wf5x-r3r6 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 GHSA-gg53-wf5x-r3r6 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-gg53-wf5x-r3r6. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-gg53-wf5x-r3r6 in your dependencies?
O3 Security finds GHSA-gg53-wf5x-r3r6 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
