4DescriptionCVE.org
A vulnerability has been found in simular-ai Agent-S 0.3.1/0.3.2. This impacts an unknown function of the file code_agent.py of the component CodeAgent. Such manipulation leads to denial of service. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Denial of service in simular-ai Agent-S 0.3.1/0.3.2 allows authenticated remote attackers to crash or exhaust the CodeAgent service by sending crafted input to code_agent.py. The root cause is CWE-404 (Improper Resource Shutdown or Release), meaning a resource - likely a subprocess, file handle, or socket - is not properly released on certain code paths, enabling resource exhaustion. …

Vulnerability AssessmentAI
| Exploitation | Low-privilege authentication to the Agent-S service is required (PR:L per CVSS 4.0 vector) - unauthenticated attackers cannot exploit this directly. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.3 (Medium) accurately reflects the limited blast radius: only availability is affected (VA:L), no confidentiality or integrity loss occurs, and low privileges are required (PR:L), preventing unauthenticated exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch has been identified at time of analysis; the vendor did not respond to the researcher's responsible disclosure. … Detailed patch versions, workarounds, and compensating controls in full report. |
