The vulnerability identified as CVE-2025-53674 affects the Jenkins Sensedia Api Platform tools Plugin version 1.0. This plugin integrates Jenkins with the Sensedia API Manager by using an integration token configured in the global Jenkins configuration form. The core issue is that the plugin fails to mask (hide) the integration token on this configuration page, meaning the token is displayed in plaintext. This increases the risk that an attacker who can access the Jenkins UI, even without authentication, could observe and capture this sensitive token. The token is used to authenticate Jenkins to the Sensedia API Manager, so its exposure could allow an attacker to perform unauthorized API calls or manipulate API configurations depending on the token's privileges. The CVSS 3.1 base score is 5.3 (medium), reflecting that the attack vector is network-based (remote), requires no privileges or user interaction, but only impacts confidentiality (token exposure) without affecting integrity or availability. The vulnerability is categorized under CWE-256 (Plaintext Storage of a Password). No patches or fixes have been published yet, and there are no known exploits in the wild. The vulnerability is significant in environments where Jenkins is used for CI/CD pipelines integrating with Sensedia API Manager, especially if Jenkins UI access is not tightly restricted. Attackers could leverage this token exposure to gain unauthorized access to API management functions, potentially leading to further compromise of API infrastructure or data leakage.

For European organizations, the primary impact is the potential unauthorized disclosure of the Sensedia API Manager integration token. This could allow attackers to interact with the API Manager, potentially extracting sensitive API configurations, modifying API policies, or disrupting API services indirectly. While the vulnerability does not directly affect Jenkins system integrity or availability, the compromise of API management credentials can lead to significant operational and security risks, including data leakage or service disruption at the API layer. Organizations relying on Jenkins for automated deployments and API lifecycle management are at risk of cascading effects if the token is misused. The risk is heightened in environments where Jenkins UI access controls are weak or where multiple users share access without strict role-based permissions. Since the vulnerability does not require authentication, any exposure of the Jenkins UI to untrusted networks or users increases the attack surface. European entities in sectors with heavy API usage such as finance, telecommunications, and technology are particularly vulnerable to the downstream effects of this token exposure.

1. Immediately restrict access to the Jenkins global configuration page to trusted administrators only, using role-based access controls and network segmentation. 2. Limit Jenkins UI exposure by placing Jenkins behind VPNs or secure gateways, preventing unauthorized external access. 3. Monitor Jenkins logs and audit trails for any unusual access patterns to the configuration pages. 4. Rotate the Sensedia API Manager integration token regularly, especially if there is any suspicion of exposure. 5. Implement multi-factor authentication (MFA) for Jenkins administrative accounts to reduce the risk of unauthorized access. 6. Follow up with the Jenkins plugin maintainers for updates or patches addressing this vulnerability and apply them promptly once available. 7. Consider temporarily disabling the Sensedia Api Platform tools Plugin if the risk outweighs the operational need until a fix is released. 8. Educate Jenkins administrators about the sensitivity of integration tokens and the importance of secure handling and masking of credentials in UI forms.
