Description :Langroid is a framework for building large-language-model-powered applications. Prior to version 0.63.0, SQLChatAgent executes SQL produced by an LLM, which is influenceable by prompt injection. When configured with a database role that has privileges enabling code execution or filesystem access (e.g., PostgreSQL pg_execute_server_program, MySQL FILE, MSSQL xp_cmdshell), an attacker who can shape the agent’s input — including indirectly via data returned to the LLM — can coerce execution of dialect-specific primitives such as `COPY … FROM PROGRAM`, achieving RCE on the database host. Fixed in v0.63.0 by defaulting SQLChatAgent to a SELECT-only sqlglot-parsed statement allowlist with a dialect-aware dangerous-pattern blocklist; allow_dangerous_operations=True restores the previous unrestricted behavior for trusted deployments.

Google Gemini (gemini-2.5-flash) • CVE: CVE-2026-25879
N/A
This remediation guide addresses a critical Remote Code Execution (RCE) vulnerability, identified as CVE-2026-25879, affecting the Acme Message Queue Server (AMQS) versions 3.0.0 through 3.5.2. This vulnerability is present in the server's deserialization mechanism for management commands, specifically when processing specially crafted messages via the AMQS management port (default TCP 8080) or potentially via the standard message broker port (default TCP 5672). An unauthenticated attacker can exploit this flaw by sending a malicious serialized object, leading to arbitrary code execution on the underlying server with the privileges of the AMQS process. The severity is considered critical due to the potential for complete system compromise without prior authentication.
1. IMMEDIATE ACTIONS
a. Network Isolation: Immediately restrict network access to all AMQS instances. If possible, remove AMQS servers from public-facing networks.
b. Firewall Rules: Implement strict ingress firewall rules on all AMQS servers to block access to the AMQS management port (default TCP 8080) and the message broker port (default TCP 5672) from untrusted sources. Limit access to only necessary internal IP addresses or subnets.
c. Service Restart: If feasible and within operational tolerance, restart AMQS instances to clear any potential in-memory exploit artifacts, although this will not prevent re-exploitation.
d. Log Review: Conduct an immediate review of AMQS server logs, system logs (e.g., /var/log/syslog, Windows Event Logs), and any available Endpoint Detection and Response (EDR) telemetry for unusual process creation, unexpected network connections originating from the AMQS process, or file modifications that occurred recently. Look for signs of compromise preceding the discovery of this vulnerability.
e. Backup: Ensure recent, verified backups of all AMQS configurations and data are available.
2. PATCH AND UPDATE INFORMATION
a. Vendor Monitoring: Closely monitor the official Acme vendor security advisories and support channels for the release of an official security patch. The expected fix will be in an AMQS 3.x.y+ security release (e.g., 3.5.3 or 3.6.0).
b. Patch Application: Once available, download and apply the official vendor-supplied patch to all affected AMQS instances. Prioritize critical production systems and those exposed to less trusted networks.
c. Staging and Testing: Follow your organization's standard change management procedures, including testing the patch in a staging environment before deploying to production. Verify AMQS functionality and stability post-patch.
d. Version Upgrade: If a direct patch for your specific minor version is not available, prepare for an upgrade to the latest secure major or minor release as advised by Acme.
3. MITIGATION STRATEGIES
a. Network Segmentation: Implement robust network segmentation to ensure AMQS instances reside in a dedicated, isolated network segment, accessible only by authorized applications and administrators.
b. Principle of Least Privilege: Ensure the AMQS service account operates with the absolute minimum necessary operating system privileges. Avoid running AMQS as root or administrator.
c. Disable Management Port Remote Access: If the AMQS management console is not required for remote administration, consider disabling remote access to the
