Attack Vector: Network
Attack Complexity: Low

User Interaction: None
Scope: Unchanged
Confidentiality: High
Integrity: None
Availability: None

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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 1 Jul 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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 13 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.

AI-suggested

Until a fix is available, restrict 'view_keypairs' permissions to trusted users only to minimize risk. Monitor Red Hat communications for updates on official fixes or workarounds.

Description

A flaw was found in foreman. Authenticated users with 'view_keypairs' permission can bypass taxonomy scoping, allowing them to download private SSH (Secure Shell) keys from other organizations by directly querying key pair IDs. This vulnerability leads to cross-tenant data exposure in multi-tenant deployments, potentially compromising sensitive information.

Impact

This vulnerability allows unauthorized access to private SSH keys across organizational boundaries in multi-tenant deployments of Red Hat Satellite 6. The exposure of private keys can lead to compromise of secure shell access credentials, potentially undermining the confidentiality of affected tenants. There is no indication of impact on integrity or availability. No known exploits in the wild have been reported.

Summary

The vulnerability in Red Hat Satellite 6 involves an authorization bypass through a user-controlled key. Authenticated users granted the 'view_keypairs' permission can circumvent taxonomy scoping restrictions, enabling them to access and download private SSH keys belonging to other organizations within the same multi-tenant environment. This flaw exposes sensitive cryptographic material across tenant boundaries, potentially compromising confidentiality. The CVSS 3.1 base score is 6.5, reflecting a medium severity with network attack vector, low attack complexity, and requiring privileges but no user interaction.
