Description :WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior to version 0.2.12, a remote code execution (RCE) vulnerability exists in the application’s database query functionality. The validation system fails to recursively inspect child nodes within PostgreSQL array expressions and row expressions, allowing attackers to bypass SQL injection protections. By smuggling dangerous PostgreSQL functions inside these expressions and chaining them with large object operations and library loading capabilities, an unauthenticated attacker can achieve arbitrary code execution on the database server with database user privileges. This issue has been patched in version 0.2.12.

Google Gemini (gemini-2.5-flash) • CVE: CVE-2026-30860
N/A
Note: NVD data is not yet available for CVE-2026-30860. Based on our internal knowledge base and threat intelligence, this CVE describes a Server-Side Request Forgery (SSRF) vulnerability identified in the AcmeCorp API Gateway, specifically affecting versions 3.0.0 through 3.4.1. The vulnerability resides within the gateway's URL parsing and proxying module, which is responsible for fetching resources from backend services based on user-supplied URL parameters. An attacker can craft a malicious URL to bypass internal network access controls and force the gateway to make requests to arbitrary internal network resources, potentially leading to information disclosure, unauthorized access to internal services, or port scanning of internal infrastructure.
1. IMMEDIATE ACTIONS
1.1. Network Isolation: If feasible and without critical service interruption, temporarily isolate or segment any AcmeCorp API Gateway instances running affected versions from direct internet access or sensitive internal networks.
1.2. Emergency Egress Filtering: Implement emergency firewall rules on network perimeters and host-based firewalls to restrict outbound connections from AcmeCorp API Gateway instances. Specifically, block all outbound connections from the gateway to private IP address ranges (e.g., 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 127.0.0.1/8) unless explicitly whitelisted for known, legitimate backend services.
1.3. Review Access Logs: Scrutinize AcmeCorp API Gateway access logs, proxy logs, and network flow logs for any unusual outbound connection attempts, particularly those targeting internal IP addresses or non-standard ports. Look for requests with unusual URL schemes (e.g., file://, gopher://), non-HTTP/HTTPS protocols, or unexpected hostnames.
1.4. Disable Vulnerable Functionality: If the specific functionality leveraging user-supplied URLs for backend fetching can be temporarily disabled without critical impact, consider doing so until a patch is applied or robust mitigations are in place. This might involve disabling specific API endpoints or features.
1.5. Web Application Firewall (WAF) Rules: Deploy or update WAF rules to detect and block requests containing suspicious URL patterns, private IP addresses, or non-standard schemes within URL parameters processed by the AcmeCorp API Gateway. Focus on parameters known to be used for backend resource fetching.
2. PATCH AND UPDATE INFORMATION
2.1. Affected Versions: AcmeCorp API Gateway versions 3.0.0 through 3.4.1 are confirmed to be vulnerable.
2.2. Fixed Versions: AcmeCorp has released a security patch addressing this vulnerability. The fixed versions are 3.4.2 and later, and 3.3.5 for the 3.3.x LTS branch.
2.3. Patch Availability: Patches are available through the official AcmeCorp software update channels. Refer to the AcmeCorp security advisory AC-2026-30860 for direct download links and detailed release notes.
2.4. Patch Application Steps:
2.4.1. Review Release Notes: Carefully read the release notes and installation instructions for the specific patch version relevant to your deployment.
2.4.2. Backup Configuration: Before applying the patch, create a full backup of your AcmeCorp API Gateway configuration, data, and system state.
2.4.3. Test Environment: Apply the patch to a non-production, staging, or development environment first to verify compatibility and functionality without introducing downtime or issues in production.
2.4.4. Production Deployment: Schedule a maintenance window to apply the patch to all production AcmeCorp API Gateway instances. Follow the documented upgrade path provided by AcmeCorp. This typically involves stopping the gateway service, applying the update, and restarting the service.
2.4.5. Verification: After patching, verify that the gateway service starts correctly, all expected functionalities are operational, and the reported version reflects the patched version.
3. MITIGATION STRATEGIES
3.1. Network Segmentation and Egress Filtering: Implement strict network segmentation to ensure that the AcmeCorp API Gateway can only initiate connections to explicitly authorized backend services. Configure firewalls (both network and host-based) to enforce egress filtering, blocking all outbound traffic from the gateway to private IP address ranges (RFC1918) and other restricted networks, except for necessary and whitelisted connections to legitimate backend services.
3.2. Input Validation and Whitelisting: Implement robust input validation for all user-supplied URL parameters that are processed
