Lifecycle Timeline
5DescriptionCVE.org
A weakness has been identified in RightNow-AI OpenFang up to 0.6.9. This vulnerability affects the function shell_exec of the file crates/openfang-runtime/src/tool_runner.rs. This manipulation causes uncontrolled memory allocation. The attack is possible to be carried out remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Uncontrolled memory allocation in RightNow-AI OpenFang up to version 0.6.9 allows remote low-privileged attackers to degrade or crash the service by sending crafted input to the shell_exec function in the openfang-runtime crate. The CVSS 4.0 vector (AV:N/PR:L/VA:L) confirms network-reachable, authenticated exploitation with limited availability impact and no confidentiality or integrity exposure. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session with at least low-level privileges on the OpenFang instance (PR:L per CVSS 4.0). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.3 (medium) is consistent with the limited blast radius: availability impact is rated VA:L (low), and subsequent-system impact metrics (SC/SI/SA) are all None, meaning exploitation does not pivot beyond the directly affected OpenFang process. … 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 coordinated disclosure. … Detailed patch versions, workarounds, and compensating controls in full report. |
