Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Adjacent: The vulnerable component is bound to the network stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
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: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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 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

To mitigate CVE-2025-25209, organizations should first upgrade Red Hat Connectivity Link to a patched version once available from Red Hat. In the interim, restrict developer persona access strictly to trusted personnel and enforce the principle of least privilege to minimize the number of users who can exploit this vulnerability. Implement network segmentation and monitoring to detect unusual HTTP traffic that could indicate secret exfiltration attempts. Enforce encryption for all internal communications, replacing HTTP with HTTPS or other secure protocols to prevent interception of secrets in transit. Review and audit secret management practices to ensure secrets are not stored or transmitted in single-line formats vulnerable to this exploit. Additionally, consider deploying runtime security tools that can detect anomalous access patterns to secrets or unauthorized namespace references. Regularly monitor logs and alerts for suspicious activity related to secret access or developer namespace operations. Finally, educate developers and administrators about the risks associated with this vulnerability and the importance of secure secret handling.

Description

The AuthPolicy metadata on Red Hat Connectivity Link contains an object which stores secretes, however it assumes those secretes are already in the kuadrant-system instead of copying it to the referred namespace. This creates space for a malicious actor with a developer persona access to leak those secrets over HTTP connection, as long the attacker knows the name of the targeted secrets and those secrets are limited to one line only.

Impact

The primary impact of CVE-2025-25209 is the unauthorized disclosure of sensitive secrets, which can compromise confidentiality significantly. Organizations relying on Red Hat Connectivity Link 1.0.1 may face risks of credential leakage, exposing internal systems or services to unauthorized access. Although the vulnerability requires a malicious actor to have developer-level access, which limits the attack surface, the ability to exfiltrate secrets over an unencrypted HTTP connection increases the risk of interception by network attackers. The integrity and availability impacts are low, but the confidentiality breach could facilitate privilege escalation, lateral movement, or data exfiltration in complex attack scenarios. This vulnerability could undermine trust in the security of internal development and deployment pipelines, especially in environments where secrets management is critical. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability becomes widely known.
