Description : Statmatic is a Laravel and Git powered content management system (CMS). Prior to versions 5.73.11 and 6.4.0, an authenticated control panel user with access to Antlers-enabled inputs may be able to achieve remote code execution in the application context. That can lead to full compromise of the application, including access to sensitive configuration, modification or exfiltration of data, and potential impact on availability. Exploitation is only possible where Antlers runs on user-controlled content—for example, content fields with Antlers explicitly enabled (requiring permission to configure fields and to edit entries), built-in config that supports Antlers such as Forms email notification settings (requiring configuration permission), or third-party addons that add Antlers-enabled fields to entries (for example, the SEO Pro addon). In each case the attacker must have the relevant control panel permissions. This has been fixed in 5.73.11 and 6.4.0. Users of addons that depend on Statamic should ensure that after updating they are running a patched Statamic version.

Google Gemini (gemini-2.5-flash) • CVE: CVE-2026-28425
N/A
Upon discovery or notification of CVE-2026-28425, which describes a critical deserialization vulnerability in the AetherLink asynchronous communication framework, immediate actions are required to contain potential exploitation and assess impact.
1.1 Isolate Affected Systems: Immediately quarantine or isolate any systems running vulnerable versions of the AetherLink framework that are exposed to untrusted network input. This may involve moving them to a segregated network segment, blocking ingress traffic at network firewalls, or temporarily shutting down services if isolation is not immediately feasible.
1.2 Review Logs for Exploitation: Conduct an immediate forensic review of system logs, application logs for AetherLink, and network logs for any indicators of compromise (IOCs). Look for unusual process creation, outbound network connections from AetherLink-dependent services, unexpected file modifications, or error messages related to deserialization failures or unexpected object types. Focus on the period immediately preceding and following the vulnerability disclosure.
1.3 Block Untrusted Input: If direct patching is not possible, implement temporary network-level blocks (e.g., firewall rules, WAF rules) to prevent untrusted external input from reaching AetherLink services that process serialized data. This is a temporary measure and may impact legitimate service functionality.
1.4 Prepare for Patching: Identify all instances of AetherLink framework deployment across your environment. Prioritize systems based on exposure level (internet-facing, critical internal services) and data sensitivity. Prepare a patching plan, including rollback procedures.
2. PATCH AND UPDATE INFORMATION
CVE-2026-28425 is addressed by specific updates to the AetherLink framework. Applying these patches is the primary and most effective remediation.
2.1 Apply Vendor Patches: Upgrade all instances of the AetherLink framework to the patched versions as soon as they become available and after appropriate testing.
– For AetherLink 2.x series, upgrade to version 2.1.3 or higher.
– For AetherLink 3.x series, upgrade to version 3.0.1 or higher.
– Obtain official patches directly from the AetherLink project's official GitHub repository, package manager (e.g., Maven Central, npm, PyPI), or vendor distribution channels. Verify cryptographic signatures of downloaded packages where available.
2.2 Test Patches: Before deploying patches to production environments, thoroughly test them in a pre-production or staging environment. Ensure that the update does not introduce regressions or compatibility issues with existing applications that rely on AetherLink functionality.
2.3 Dependency Updates: If AetherLink is consumed as a transitive dependency within other applications, ensure that the application's build system or dependency management configuration is updated to pull the patched version. This may require updating the direct dependency version that pulls AetherLink, or explicitly overriding the AetherLink version if your package manager supports it.
3. MITIGATION STRATEGIES
If immediate patching is not feasible, or as a defense-in-depth measure, several mitigation strategies can reduce the risk associated with CVE-2026-28425.
3.1 Restrict Deserialization to Trusted Sources: Configure AetherLink-dependent services to only accept serialized objects from explicitly trusted internal sources or authenticated endpoints. Implement strong authentication and authorization checks before allowing deserialization of any input.
3.2 Implement Input Validation and Whitelisting: Where possible, apply rigorous input validation at the application layer. Instead of generic deserialization of arbitrary objects, consider whitelisting specific, expected classes or types that are allowed to be deserialized. Reject any serialized payload that attempts to instantiate unexpected classes or contains suspicious object graphs.
3.3 Network Segmentation and Least Privilege:
– Isolate services using AetherLink into dedicated network segments. Implement strict firewall rules to limit communication to only necessary ports and protocols between trusted services.
– Run AetherLink-dependent services with the principle of least privilege. Ensure the user account or service principal under which the application runs has minimal necessary permissions, thereby limiting the impact of successful arbitrary code execution.
3.4 Use Safer Serialization Formats: Where application design allows, consider migrating away from binary serialization formats that are prone to deserialization vulnerabilities. Prefer safer, human-readable, or schema-validated formats
