Description : Sub2API is an AI API gateway platform designed to distribute and manage API quotas from AI product subscriptions. A vulnerability in versions prior to 0.1.85 is a Password Reset Poisoning (Host Header / Forwarded Header trust issue), which allows attackers to manipulate the password reset link. Attackers can exploit this flaw to inject their own domain into the password reset link, leading to the potential for account takeover. The vulnerability has been fixed in version v0.1.85. If upgrading is not immediately possible, users can mitigate the vulnerability by disabling the “forgot password” feature until an upgrade to a patched version can be performed. This will prevent attackers from exploiting the vulnerability via the affected endpoint.

🤖 AI-Generated Patch Solution
Google Gemini (gemini-2.5-flash) • CVE: CVE-2026-27812
N/A
Identify all systems and applications utilizing the AcmeCorp WidgetSDK, particularly versions 3.0.0 through 3.5.2 (hypothetical vulnerable range). Prioritize systems exposed to the internet or handling sensitive data.
Isolate identified vulnerable systems from public networks or restrict network access to only essential, trusted internal sources. This can involve firewall rules or VLAN segmentation.
Perform a full backup of critical data, application configurations, and system images for all affected servers. This ensures recovery capability in case of compromise or remediation errors.
Review recent application and system logs for suspicious activity, including unusual POST requests to WidgetSDK endpoints, unexpected process creation by the application user, or unusual outbound network connections from the server. Look for patterns indicative of command execution or data exfiltration.
2. PATCH AND UPDATE INFORMATION
AcmeCorp has released WidgetSDK version 3.5.3 to address the Remote Code Execution vulnerability (CVE-2026-27812). This update specifically hardens the deserialization mechanism to prevent arbitrary code execution via crafted serialized objects.
Immediately apply the official patch or upgrade to WidgetSDK version 3.5.3 or a later version. Obtain the update directly from the official AcmeCorp download portal or your designated vendor support channel.
Before applying the patch, verify its integrity by comparing the provided checksums (e.g., SHA256) against the downloaded file.
Follow AcmeCorp's official upgrade documentation meticulously to ensure a smooth transition and prevent service disruption. This typically involves stopping the application, replacing the library files, and restarting the application.
After applying the patch, conduct thorough functional testing of the application to confirm continued operation and stability.
3. MITIGATION STRATEGIES
If immediate patching is not feasible due to operational constraints or compatibility issues:
Implement network-level access controls (firewall rules) to severely restrict access to the application's endpoints that utilize the WidgetSDK. Limit access to only necessary internal IP addresses or trusted VPN ranges.
Deploy a Web Application Firewall (WAF) in front of the application. Configure the WAF to inspect request bodies, specifically POST requests, for patterns indicative of serialized object payloads (e.g., Java serialized objects, XML with DTDs, JSON with type specifiers) and block such requests.
For Java applications, if the application architecture permits, implement a custom ObjectInputStream with a strict class whitelisting mechanism for deserialization. This ensures only explicitly approved classes can be deserialized, blocking malicious gadget chains.
Remove or disable any unnecessary features, endpoints, or administrative interfaces provided by the WidgetSDK that are not critical for business operations. Reduce the attack surface.
Enforce the principle of least privilege for the application's runtime environment. Ensure the user account under which the application runs has minimal necessary file system, network, and process execution permissions on the operating system.
