Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

CVE published 15 Sep 2026
Detectable: no evidence on record.

Exploited in the wildExploited: no evidence on record.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

A patch is available for Shopper Framework versions prior to 2.9.2 that adds the missing authorization check to the Media sub-form store() method. Users should upgrade to version 2.9.2 or later to remediate this vulnerability. Until patched, restrict admin panel access to trusted users and monitor for unauthorized media changes. No other mitigations are specified by the vendor advisory.

Description

Shopper is a Headless e-commerce Admin Panel. Prior to 2.9.2, an earlier product sub-form hardening change left store() in packages/admin/src/Livewire/Components/Products/Form/Media.php without the edit_products authorization check used by sibling sub-forms. An authenticated staff user with browse_products can invoke the Livewire store action and replace the thumbnail and gallery images for a product whose Media component was initialized, even without product-edit permission. The product binding is locked, so the attacker cannot redirect the update to an arbitrary product through client-side ID substitution, and the impact is limited to products whose edit pages were loaded. This issue is fixed in version 2.9.2.

Impact

An attacker with a browse_products permission but without edit_products can update product images (thumbnail and gallery) for any product whose edit page they have visited. This can lead to misleading or adversarial product images on the storefront without proper authorization or audit trail. The impact is limited to products accessed in the attacker's session. There is no confidentiality or availability impact reported.

Summary

The Shopper Framework's Media sub-form store() method in packages/admin/src/Livewire/Components/Products/Form/Media.php lacks an authorize() call, unlike sibling components fixed in a prior advisory (GHSA-h4mp-g9c6-xwph). This omission allows any authenticated admin user with browse_products permission but without edit_products permission to update product media (thumbnail and gallery images) for products they have loaded in their session. The product ID is locked server-side, preventing arbitrary product modification, but the missing permission gate allows unauthorized media updates. The vulnerability is identified as CVE-2026-56830 with a CVSS 3.1 score of 6.5 and is classified as CWE-862 (Missing Authorization). A patch is available to add the authorize('edit_products') call to the store() method.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
