InnoShop Improper Authentication Vulnerability (CVE-2026-7630)

A critical vulnerability, CVE-2026-7630, affects innocommerce InnoShop versions up to 0.7.8. The vulnerability resides in the InstallServiceProvider::boot function within the innopacks/install/src/InstallServiceProvider.php file, which governs the installation endpoint. Successful exploitation allows remote attackers to bypass authentication mechanisms, potentially leading to complete system compromise. Publicly available exploits exist, increasing the risk of active exploitation. It is crucial for administrators to apply the provided patch (identifier: 45758e4ec22451ab944ae2ae826b1e70f6450dc9) immediately.

Attack Chain

1. An attacker identifies an InnoShop instance running a vulnerable version (<= 0.7.8).
2. The attacker crafts a malicious HTTP request targeting the installation endpoint (innopacks/install/src/InstallServiceProvider.php).
3. The request exploits the improper authentication in the InstallServiceProvider::boot function.
4. Authentication checks are bypassed due to the vulnerability.
5. The attacker gains unauthorized access to the installation process.
6. The attacker injects malicious code or configurations during the installation phase.
7. The injected code executes with elevated privileges, granting the attacker control over the InnoShop instance.
8. The attacker establishes a persistent backdoor for future access and potential data exfiltration or further malicious activities.

Impact

Successful exploitation of CVE-2026-7630 allows unauthenticated remote attackers to compromise InnoShop installations. This can lead to complete control of the web server, potentially affecting sensitive customer data, financial information, and intellectual property. Given the ease of exploitation and publicly available exploits, unpatched InnoShop instances are at high risk of compromise. The number of affected installations is currently unknown, but the widespread use of InnoShop in e-commerce makes this a significant threat.

Recommendation

• Immediately apply the patch identified by 45758e4ec22451ab944ae2ae826b1e70f6450dc9 to remediate the improper authentication vulnerability.
• Deploy the Sigma rule “Detect InnoShop Installation Endpoint Access” to identify unauthorized access attempts to the installation endpoint.
• Monitor web server logs for suspicious activity targeting the innopacks/install/src/InstallServiceProvider.php path, based on “Detect InnoShop Installation Endpoint Access” to identify post-exploitation attempts.
