Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.

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-p5v9-g8w8-5q4v 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 377,166 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

Description
Impact
Any user (logged in or not) with access to the page XWiki.XWikiUserProfileSheet can enable or disable any user profile. This might allow to a disabled user to re-enable themselves, or to an attacker to disable any user of the wiki.
Patches
The problem has been patched in XWiki 13.10.7, 14.5RC1 and 14.4.2.
Workarounds
The problem can be patched immediately by editing the page XWiki.XWikiUserProfileSheet in the wiki and by performing the changes contained in https://github.com/xwiki/xwiki-platform/commit/5be1cc0adf917bf10899c47723fa451e950271fa.

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-user-profile-ui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.xwiki.platform:xwiki-platform-user-profile-ui to 13.10.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p5v9-g8w8-5q4v 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-p5v9-g8w8-5q4v can be triaged on real exposure rather than presence alone.
Tailored to GHSA-p5v9-g8w8-5q4v. 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-p5v9-g8w8-5q4v in your dependencies?
O3 Security finds GHSA-p5v9-g8w8-5q4v across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
