GHSA-hr9v-r8r2-hg7j is a high-severity (CVSS 8.7) Cross-site Scripting (XSS) vulnerability in shopper/framework. O3 Security confirms whether GHSA-hr9v-r8r2-hg7j is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Shopper: Multiple data integrity and disclosure issues in admin Livewire components
Exploitation Status
No confirmed exploitation observed yet
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

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-hr9v-r8r2-hg7j 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 0 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.

Description
Impact
Three related defects on admin Livewire components allowed data tampering, sensitive data disclosure, and stored XSS:
- IDOR via unlocked properties. Several Livewire components in the admin panel exposed Eloquent model identifiers as public properties without the
#[Locked]attribute. An authenticated user could rewrite the wire payload from the browser to target any record id, bypassing the implicit scoping enforced by the page routing. - Sensitive data echoed back through Hidden form field.
Customers/Create::store()re-passed aHidden_passwordform field straight into the create payload. The plaintext password was rendered into the HTML and transported through the Livewire snapshot in clear text, exposing credentials in the page DOM and in any logging that captures Livewire payloads. - Stored XSS on product barcode. The product barcode field was rendered through
DNS1DFacade::getBarcodeHTML()with{!! !!}. An attacker withedit_productspermission could persist malicious payload in the barcode field that would execute in the browser of any admin user viewing that product, enabling session theft and privileged-action chaining.
Patches
Fixed in v2.8.0:
- All vulnerable Livewire model identifiers are now marked
#[Locked]. Customers/Createno longer round-trips the password through a Hidden form field; the plaintext password is hashed at action boundary and never returned to the client.- The product barcode rendering now escapes the value before passing it to the barcode generator and the output is wrapped in an
<svg>context that does not interpret event handlers.
Upgrade via:
composer require shopper/admin:^2.8
Workarounds

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for shopper/framework. 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 shopper/framework to 2.8.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hr9v-r8r2-hg7j 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-hr9v-r8r2-hg7j 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-hr9v-r8r2-hg7j. 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-hr9v-r8r2-hg7j in your dependencies?
O3 detects GHSA-hr9v-r8r2-hg7j across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
