GHSA-g67g-hvc3-xmvf
CRITICALInconsistent input sanitisation leads to XSS vectors
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.
Blast Radius
omero-web🐍omero-figureReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
Background
A variety of templates do not perform proper sanitization through HTML escaping.
Due to the lack of sanitization and use of jQuery.html(), there are a whole host of XSS possibilities with specially crafted input to a variety of fields.
Impact
OMERO.web before 5.11.0 and OMERO.figure before 4.4.1.
Patches
Users should upgrade OMERO.web to 5.11.0 or higher and OMERO.figure to 4.4.1 or higher.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐍PyPI | omero-web | all versions | 5.11.0 |
| 🐍PyPI | omero-figure | all versions | 4.4.1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for omero-web. 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 omero-web to 5.11.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g67g-hvc3-xmvf 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-g67g-hvc3-xmvf 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-g67g-hvc3-xmvf. 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-g67g-hvc3-xmvf in your dependencies?
O3 detects GHSA-g67g-hvc3-xmvf across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
