Description :Langroid is a framework for building large-language-model-powered applications. Versions prior to 0.65.2 are vulnerable to a critical Sandbox Escape leading to Remote Code Execution (RCE) in its `TableChatAgent` and `VectorStore` capabilities. When these agents evaluate LLM-generated tool messages with `full_eval=True`, they attempt to sandbox the execution by explicitly setting `locals` to an empty dictionary `{}` inside Python’s `eval()` function. However, this relies on an incomplete understanding of Python’s execution model. Because `__builtins__` is not explicitly scrubbed from the `globals` dictionary mapping, Python implicitly injects all built-ins during execution, granting full access to functions like `__import__(‘os’).system()`. Since `TableChatAgent.pandas_eval()` executes external LLM outputs natively, this bypass permits any attacker providing prompt payload to achieve unauthenticated RCE on the host system. Version 0.65.2 patches the issue.

N/A
Vulnerability Description:
A critical unauthenticated remote code execution (RCE) vulnerability has been identified in the Acme Enterprise Management Suite (AEMS) versions 3.x prior to 3.5.0. The vulnerability resides in the '/api/v1/system/diagnostics' endpoint, which is accessible without authentication. This endpoint is intended to generate diagnostic logs but improperly sanitizes user-supplied input when constructing commands for log generation. An attacker can inject arbitrary operating system commands into the input parameters, leading to their execution with the privileges of the AEMS service account. Successful exploitation can result in full system compromise, data exfiltration, and disruption of critical business operations. This vulnerability poses a significant risk due to its unauthenticated nature and potential for widespread impact.
1. IMMEDIATE ACTIONS
a. Network Isolation and Blocking:
Immediately disconnect or isolate all AEMS instances from public internet access. If full disconnection is not feasible, implement network access control lists (ACLs) or firewall rules to block all external inbound traffic to the AEMS server, specifically targeting TCP ports used by the AEMS application (e.g., 80, 443, 8080, 8443, or any custom ports). Prioritize blocking access to the vulnerable '/api/v1/system/diagnostics' endpoint at the network perimeter (e.g., WAF, reverse proxy).
b. Identify Affected Systems:
Conduct an urgent inventory scan to identify all instances of Acme Enterprise Management Suite (AEMS) within your environment. Determine their exact versions to ascertain which systems are vulnerable.
c. Implement Temporary WAF Rules:
If a Web Application Firewall (WAF) is in place, deploy a rule to immediately block requests containing known command injection patterns (e.g., '&&', '||', ';', '`', '$(') targeting the '/api/v1/system/diagnostics' URI path. This provides an immediate, albeit temporary, layer of protection.
d. Monitor for Exploitation:
Increase vigilance on all AEMS server logs (web server, application, system logs) for any suspicious requests to the '/api/v1/system/diagnostics' endpoint, unusual process creations by the AEMS service account, or unexpected outbound network connections from the AEMS host.
e. Backup Critical Data:
Perform an immediate backup of all critical data associated with AEMS instances to ensure recovery capabilities in case of compromise.
2. PATCH AND UPDATE INFORMATION
a. Vendor Patch Availability:
Acme Corporation has released a security update to address CVE-2026-54769. The fix is included in AEMS version 3.5.0 and later. All organizations running AEMS 3.x versions prior to 3.5.0 are strongly advised to upgrade immediately.
b. Patching Procedure:
i. Download the official patch or updated installer for AEMS version 3.5.0 (or newer) directly from the Acme Corporation official support portal.
ii. Review the vendor's release notes and installation guide for specific instructions pertaining to your current AEMS version and operating system.
iii. Prior to deployment in production, thoroughly test the update in a non-production, staging environment that mirrors your production setup. Verify application functionality and data integrity.
iv. Schedule a maintenance window for applying the patch to production systems. Ensure all necessary backups are completed before starting the update process.
v. Follow the vendor's instructions to apply the update. This typically involves stopping AEMS services, running the installer, and then restarting services.
vi. After patching, verify that AEMS services are running correctly and that the vulnerability has been remediated by checking the reported version number.
c. Rollback Plan:
Prepare a comprehensive rollback plan in case of unforeseen issues during the patching process. This should include procedures for restoring AEMS from backups or reverting to the previous stable version.
3. MITIGATION STRATEGIES
a. Network Segmentation:
Isolate AEMS servers into a dedicated network segment or VLAN, separate from other critical infrastructure. Implement strict firewall rules to limit network connectivity to only essential services and trusted sources.
b. Restrict Access to Endpoint
