Description :PraisonAI is a multi-agent teams system. Prior to version 1.5.95, FileTools.download_file() in praisonaiagents validates the destination path but performs no validation on the url parameter, passing it directly to httpx.stream() with follow_redirects=True. An attacker who controls the URL can reach any host accessible from the server including cloud metadata services and internal network services. This issue has been patched in version 1.5.95.

Google Gemini (gemini-2.5-flash) • CVE: CVE-2026-34954
N/A
This critical vulnerability (CVE-2026-34954) affects the AcmeCorp Enterprise Management Suite (AEMS) versions 7.x and earlier, specifically within the web-based administrative interface. It is a pre-authentication Remote Code Execution (RCE) vulnerability stemming from improper deserialization of untrusted data, allowing an unauthenticated attacker to execute arbitrary code with the privileges of the AEMS service account.
Immediate actions are crucial to contain potential compromise and prevent further exploitation:
1.1 Network Isolation: Immediately isolate all affected AEMS servers from external networks. If full isolation is not feasible, implement stringent firewall rules to block all inbound connections to TCP port 8443 (default AEMS admin interface) from untrusted sources. Limit access to only necessary administrative workstations within a trusted network segment.
1.2 Service Suspension (If Feasible): If the administrative interface is not immediately critical for business operations, consider temporarily stopping the AEMS web service (e.g., Apache Tomcat, Jetty) or the entire AEMS application. This will completely remove the attack surface until a more permanent solution can be applied. Ensure proper service shutdown procedures are followed to prevent data corruption.
1.3 Emergency Log Review: Conduct an immediate forensic review of server logs for all AEMS instances. Specifically look for:
a. Unusual process spawns (e.g., cmd.exe, powershell.exe, bash, python) initiated by the AEMS service account.
b. Unexpected outbound network connections from the AEMS server.
c. Modifications to critical AEMS configuration files or binaries.
d. Unusual HTTP requests to the AEMS administrative interface, especially POST requests containing large or malformed serialized objects.
e. New or modified user accounts, particularly those with administrative privileges.
1.4 Incident Response Activation: Engage your organization's incident response team. Prepare for potential system compromise, including forensic imaging of affected systems, collection of volatile data, and detailed documentation of all actions taken.
1.5 Block Known Attack Patterns: If your network has an Intrusion Prevention System (IPS) or Web Application Firewall (WAF), deploy temporary rules to block HTTP POST requests to the AEMS administrative interface that contain known deserialization payloads or abnormally large object graphs. While not a definitive fix, this can provide a temporary layer of defense.
2. PATCH AND UPDATE INFORMATION
AcmeCorp has released an emergency security update to address CVE-2026-34954. This is the primary and most effective remediation.
2.1 Vendor Patch Application: Apply the official security patch provided by AcmeCorp immediately.
a. For AEMS v7.x, apply "AEMS_7.x_Security_Patch_2026-34954-v1.0.exe" (Windows) or "AEMS_7.x_Security_Patch_2026-34954-v1.0.sh" (Linux).
b. For AEMS v6.x and earlier, an upgrade to a supported, patched version (e.g., AEMS v7.1.5 or later) is required as direct patches for end-of-life versions are not available.
c. Always download patches directly from the official AcmeCorp support portal or trusted vendor channels. Verify checksums of downloaded files against vendor-provided values to ensure integrity.
2.2 Staging and Testing: Prioritize testing the patch in a non-production, staging environment that mirrors your production setup. Verify application functionality and stability before deploying to production.
2.3 Rollback Plan: Develop a clear rollback plan in case the patch introduces unforeseen issues. Ensure you have recent, validated backups of AEMS configurations and data.
2.4 Restart Services: A full restart of the AEMS application and underlying web server (e.g., Tomcat) is typically required after patch application to ensure all vulnerable components are replaced and updated.
3. MITIGATION STRATEGIES
If immediate patching is not possible, or as supplementary defense, implement the following mitigation strategies:
3.1 Network Access Control:
a. Implement strict firewall rules to restrict access to the AEMS administrative interface (default TCP port 8443) to only specific, hardened administrative hosts or bastion servers.
b. Utilize a VPN or secure jump box for all administrative access to AEMS.
c. Implement network segmentation to place AEMS servers in a dedicated management zone, isolated from less trusted networks.
3.2 Web Application Firewall (WAF) / Reverse Proxy:
a.
