HighCVSS 8.1 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 32/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.50% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: shopperlabs shopper 2.9.2.

Low priority for now. Upgrade to shopperlabs shopper 2.9.2 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Shopper is a Headless e-commerce Admin Panel. Prior to 2.9.2, groupedBulkActions in packages/admin/src/Livewire/Pages/Attribute/Browse.php, packages/admin/src/Livewire/Pages/Tag/Index.php, packages/admin/src/Livewire/Pages/Brand/Index.php, packages/admin/src/Livewire/Pages/Category/Index.php, and packages/admin/src/Livewire/Pages/Supplier/Index.php omit server-side authorization while the pages require only browse_attributes, browse_tags, browse_brands, browse_categories, or browse_suppliers. A browse-only staff user can invoke DeleteBulkAction to mass delete attributes or tags and can invoke BulkAction::make('enabled') or BulkAction::make('disabled') to change attribute, brand, category, or supplier visibility. These operations can break product variants and substantially disrupt storefront catalog visibility. Per-record actions and the comparison pages identified by the advisory are correctly authorized and are not affected. This issue is fixed in version 2.9.2.
