CVE-2026-8292: Denial of Service in Open5GS
A security vulnerability has been detected in Open5GS up to 2.7.7. The affected element is the function yuarel_parse in the library /lib/sbi/conv.c of the component NRF. Such manipulation of the argument hnrf-uri leads to denial of service. The attack may be performed from remote. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.
AI Analysis
Technical Summary
This vulnerability in Open5GS (up to version 2.7.7) involves the yuarel_parse function within the NRF component's /lib/sbi/conv.c source file. By manipulating the hnrf-uri argument, an attacker can trigger a denial of service condition remotely. The vulnerability has a CVSS 4.0 base score of 5.3, indicating medium severity, with low attack complexity and no required privileges or user interaction. The Open5GS project was notified early but has not yet responded with a fix or mitigation guidance.
Potential Impact
Successful exploitation results in denial of service of the NRF component in Open5GS, potentially disrupting network function reliant on this element. The vulnerability can be triggered remotely without authentication, which increases risk. However, there is no indication of privilege escalation, data disclosure, or code execution. No known exploits are reported in the wild at this time.
Mitigation Recommendations
No official patch or remediation is currently available from the vendor. Users should monitor the Open5GS project for updates or advisories. Until a fix is released, consider limiting exposure of the NRF component to untrusted networks to reduce risk. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
