CVE-2026-10113: Open5GS Shared NF-profile nnrf-handler.c denial of service
A vulnerability was found in Open5GS up to 2.7.7. Affected by this vulnerability is an unknown functionality in the library lib/sbi/nnrf-handler.c of the component Shared NF-profile Parser. The manipulation results in denial of service. It is possible to launch the attack remotely. The exploit has been made public and could be used. A patch should be applied to remediate this issue.
Security readout for executives and security teams
Plain-English summary
CVE-2026-10113 can let a remote, low-privileged actor crash or disrupt Open5GS components by abusing shared NF-profile parsing. Business impact is service availability, not data theft. It matters most for production private 5G or lab networks where Open5GS control-plane services are reachable.
Executive priority
Treat as a moderate availability risk. Patch during the next controlled maintenance window, faster if Open5GS supports production connectivity or exposes control-plane services outside a trusted segment.
Technical view
Open5GS 2.7.0 through 2.7.7 are listed as affected. The issue is in lib/sbi/nnrf-handler.c, tied to the Shared NF-profile parser, and maps to CWE-404. CVSS v4.0 is 5.3 with network access, low complexity, low privileges, no user interaction, and low availability impact.
Likely exposure
Exposure is likely limited to organizations running Open5GS 2.7.0-2.7.7, especially where SBI or NF registration paths are reachable beyond tightly controlled network-function peers.
Exploitation context
The source bundle says a public exploit exists and could be used. KEV is false, and the provided sources do not show confirmed active exploitation. The CVSS vector indicates remote exploitation requires low privileges.
Researcher notes
Evidence identifies the affected file and parser but not detailed root cause mechanics in the provided bundle. Public exploit availability is reported, but active exploitation is not established. Avoid assuming confidentiality or integrity impact beyond the CVSS data.
Mitigation direction
Check Open5GS version and prioritize 2.7.0 through 2.7.7 systems.
Review upstream PR #4527 and vendor guidance before applying fixes.
Apply the vendor patch or fixed release after environment testing.
Restrict Open5GS control-plane interfaces to trusted network-function peers.
Monitor Open5GS services for unexpected crashes or restart loops.
Validation and detection
Inventory Open5GS deployments and record exact running versions.
Confirm whether affected SBI or NRF-related paths are reachable remotely.
Verify whether the patch from PR #4527 or a fixed release is present.
Review logs for unexplained Open5GS service termination or availability drops.
Retest availability controls without using public exploit procedures.

These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Improper Resource Shutdown or Release
Improper Resource Shutdown or Release represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
