CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N

Attack Vector: Network
Attack Complexity: Low
Privileges Required: 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.

Detectable: no evidence on record.
No public nuclei template indexed

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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 14 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

The vendor advisory references security updates for Red Hat Satellite 6.19 for RHEL 9 but does not explicitly confirm a patch for version 6.16 on RHEL 8 in the provided data. Until a patch is applied, restrict user permissions to prevent access to create_personal_access_tokens where possible.

Description

CVE-2026-56097 is an SQL injection vulnerability in the Red Hat Satellite Katello Registry Proxy component. It arises from improper sanitization of user-supplied labels in database queries within the RegistryProxiesController. The flaw can be exploited by users with only the create_personal_access_tokens permission, even if their access is restricted and they have no Organization or Location assigned.

Impact

Successful exploitation of this vulnerability could allow an attacker with limited permissions to perform SQL injection attacks, potentially leading to unauthorized disclosure of sensitive information from the database. The impact is limited to confidentiality, with no direct integrity or availability effects reported.

Summary

This vulnerability exists in rubygem-katello used by Red Hat Satellite 6.16 for RHEL 8. The RegistryProxiesController methods check_blob_push_org_label and get_matching_products_from_org interpolate user-supplied labels directly into raw SQL fragments without proper sanitization, leading to SQL injection. The flaw is exploitable by users with minimal permissions (create_personal_access_tokens), potentially allowing unauthorized data access. The CVSS v3.1 base score is 6.5 (medium severity), reflecting network attack vector, low attack complexity, low privileges required, no user interaction, unchanged scope, high confidentiality impact, and no integrity or availability impact. No known exploits in the wild are reported. The vendor advisory references a security update for Red Hat Satellite 6.19.5 on RHEL 9 but does not explicitly confirm a patch for 6.16 on RHEL 8 in the provided text.
