GHSA-rx9f-5ggv-5rh6
MEDIUMGHSA-rx9f-5ggv-5rh6 is a medium-severity (CVSS 6.8) Cross-site Scripting (XSS) vulnerability in decidim-admin. O3 Security confirms whether GHSA-rx9f-5ggv-5rh6 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Decidim::Admin vulnerable to cross-site scripting (XSS) in the admin activity log
Blast Radius
decidim-admin💎decidim-adminReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects RubyGems packages — download data is not available via public APIs for these ecosystems.
Description
Impact
The admin panel is subject to potential XSS attach in case an admin assigns a valuator to a proposal, or does any other action that generates an admin activity log where one of the resources has an XSS crafted.
Patches
N/A
Workarounds
Redirect the pages /admin and /admin/logs to other admin pages to prevent this access (i.e. /admin/organization/edit)

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for decidim-admin. 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 decidim-admin to 0.27.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rx9f-5ggv-5rh6 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-rx9f-5ggv-5rh6 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-rx9f-5ggv-5rh6. 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-rx9f-5ggv-5rh6 in your dependencies?
O3 detects GHSA-rx9f-5ggv-5rh6 across RubyGems dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
