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 9 Jul 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: 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 26 Oct 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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

Restrict Jenkins job configuration access strictly to trusted and necessary personnel to minimize exposure to sensitive credentials.
Implement role-based access control (RBAC) and audit permissions regularly to ensure least privilege principles are enforced.
Monitor Jenkins logs and job configuration changes for unusual activity that could indicate credential harvesting attempts.
Avoid storing sensitive API keys and encryption keys directly in Jenkins job configurations; use Jenkins credentials store or external secret management solutions that mask or encrypt secrets properly.
Educate Jenkins administrators and users about the risks of credential exposure and encourage secure handling practices.
Apply network segmentation and multi-factor authentication (MFA) to Jenkins access to reduce risk of unauthorized access.
Stay alert for official patches or updates from the Jenkins project and apply them promptly once available.
Consider temporary disabling or replacing the Nouvola DiveCloud Plugin if feasible until a fix is released.
Conduct regular security assessments of CI/CD pipelines to identify and remediate similar credential exposure risks.

Description

Jenkins Nouvola DiveCloud Plugin 1.08 and earlier does not mask DiveCloud API Keys and Credentials Encryption Keys displayed on the job configuration form, increasing the potential for attackers to observe and capture them.

Impact

For European organizations, this vulnerability poses a significant confidentiality risk, especially in environments where multiple users have job configuration permissions in Jenkins. Exposure of DiveCloud API keys and encryption keys can lead to unauthorized access to cloud resources, potentially resulting in data breaches or service disruptions. Organizations relying on Jenkins for continuous integration and deployment may face increased risk of credential theft, which could be leveraged for further attacks such as privilege escalation or lateral movement. The impact is heightened in sectors with stringent data protection requirements like finance, healthcare, and critical infrastructure. Since the vulnerability does not affect integrity or availability directly, the primary concern is unauthorized data access and potential misuse of credentials. The lack of masking also increases the risk from insider threats or accidental exposure during routine configuration reviews. The absence of patches means organizations must rely on access controls and monitoring to mitigate risk in the short term.

CWE-256Plaintext Storage of a Password (opens in a new tab)
Base weaknessLikelihood of exploit: HighOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product stores a password in plaintext within resources such as memory or files.
Architecture and Design
Avoid storing passwords in easily accessible locations.
Architecture and Design
Consider storing cryptographic hashes of passwords as an alternative to storing in plaintext.
A programmer might attempt to remedy the password management problem by obscuring the password with an encoding function, such as base 64 encoding, but this effort does not adequately protect the password because the encoding can be detected and decoded easily.
