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.

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

Red Hat advises granting the Job Template and Workflow Job Template administrator roles only to trusted users and avoiding storing webhook token credentials in organizations where untrusted users hold template-admin rights. There is no complete configuration-only mitigation. Users should apply the official fix when it becomes available.

Description

An incorrect authorization vulnerability in AWX, the automation controller component of Red Hat Ansible Automation Platform, allows a user with job template administration rights to attach a webhook token credential they do not have permission to use. This flaw can lead to disclosure of another user's personal access token when a webhook event triggers AWX to send the decrypted token to an attacker-controlled destination. The impact is limited to confidentiality of the credential with no direct integrity or availability effects. Red Hat rates this flaw as Moderate and recommends restricting template administrator roles to trusted users and applying the forthcoming fix.

Impact

An authenticated user with permission to administer a job template or workflow job template and use its project and inventory can attach a webhook token credential they do not have use permission on. This leads to disclosure of another user's personal access token when AWX decrypts and sends the token in a webhook event request header to an attacker-influenced destination. The impact is limited to confidentiality loss of the credential; there is no direct impact on integrity or availability of the automation controller.

Summary

CVE-2026-126642 is an authorization flaw in AWX's API access classes for JobTemplate and WorkflowJobTemplate. The flaw arises because the access control checks omit verifying the caller's Credential use_role when assigning the webhook_credential foreign key. Specifically, JobTemplateAccess.can_add/can_change and WorkflowJobTemplateAccess.can_change do not perform the check_related call that is standard for many-to-many credential relationships. Consequently, a user who can administer their own job template and use its project and inventory can attach a webhook token credential (e.g., a GitLab token) they lack permission to use. When a webhook event occurs, AWX decrypts and sends the token in a request header to a status URL derived from the event payload, potentially disclosing the token to an attacker-controlled destination. Exploitation requires authenticated users with template admin rights and knowledge of the webhook token credential ID. The impact is confidentiality loss of another user's personal access token, with no integrity or availability impact to the controller. Red Hat classifies this as a Moderate severity issue with a CVSS 3.1 score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).
