GHSA-7f2f-pcv3-j2r7
MEDIUMGHSA-7f2f-pcv3-j2r7 is a medium-severity (CVSS 4.3) Information Exposure vulnerability in org.xwiki.platform:xwiki-platform-tag-api. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-7f2f-pcv3-j2r7 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

org.xwiki.platform:xwiki-platform-tag-api☕org.xwiki.platform:xwiki-platform-tag-apiReal-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
Tags from pages not viewable to the current user are leaked by the tags API. This information can also be exploited to infer the document reference of non-viewable pages.
Patches
This vulnerability has been patched in XWiki 14.4.8, 14.10.4, and 15.0 RC1.
Workarounds
There is no workaround apart from upgrading to a fixed version.

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-tag-api. 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.xwiki.platform:xwiki-platform-tag-api to 14.4.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7f2f-pcv3-j2r7 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-7f2f-pcv3-j2r7 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-7f2f-pcv3-j2r7. 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-7f2f-pcv3-j2r7 in your dependencies?
O3 detects GHSA-7f2f-pcv3-j2r7 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
