Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

CVE published 10 Nov 2026
Detectable: no evidence on record.
No public nuclei template indexed

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 10 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

Description

CVE-2026-95780 is a vulnerability in Hewlett Packard Enterprise's Private 5G Core (P5G Core) affecting versions up to 1.26.1.4. It involves flaws in authentication and session management that may allow a remote user with prior legitimate access to maintain unauthorized access to protected resources beyond the intended session termination. The vulnerability has a high severity score of 8.1 and does not require user interaction for exploitation.

Impact

Successful exploitation allows a remote attacker with prior legitimate access to retain unauthorized access to protected system resources beyond the intended authorization period. This compromises confidentiality and integrity of the affected system components. There is no indication of availability impact. No known exploits are reported in the wild at this time.

Summary

This vulnerability affects the authentication and session management mechanisms of HPE Private 5G Core (P5G Core) software versions up to 1.26.1.4. Under certain conditions, a remote user who previously had legitimate access may continue to access protected system resources even after account or session state changes that should have terminated access. The flaw could lead to unauthorized access persistence, compromising confidentiality and integrity without impacting availability. The CVSS v3.1 base score is 8.1, reflecting network attack vector, low attack complexity, required privileges, no user interaction, and high impact on confidentiality and integrity.
