Scope: Unchanged
Confidentiality: Low
Integrity: Low
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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
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: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 16 Dec 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 2026-10-25.

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 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 primary mitigation is to upgrade JetBrains TeamCity to version 2025.11.1 or later, where the vulnerability has been fixed by replacing GitHub personal access tokens with installation tokens. Organizations should also audit their current token usage in TeamCity integrations to identify any stored PATs and revoke or replace them with installation tokens where possible. Implement strict access controls and monitoring around CI/CD systems to detect unusual token usage or repository access patterns. Employ role-based access control (RBAC) to limit who can configure or access tokens within TeamCity. Additionally, enforce secure storage and rotation policies for all credentials used in CI/CD pipelines. Regularly review and update integration permissions to adhere to the principle of least privilege. Finally, maintain awareness of JetBrains security advisories and apply patches promptly.

Description

In JetBrains TeamCity before 2025.11.1 excessive privileges were possible due to storing GitHub personal access token instead of an installation token

Impact

For European organizations, this vulnerability poses a risk primarily to the confidentiality and integrity of source code and related assets managed through TeamCity integrations with GitHub. Unauthorized access via excessive privileges could allow attackers to modify build configurations, inject malicious code, or exfiltrate sensitive information. This could disrupt software supply chains and damage organizational reputation. Given the widespread use of JetBrains TeamCity in software development environments across Europe, especially in countries with large tech sectors, the impact could be significant if exploited. However, the absence of known exploits and the medium severity rating suggest the threat is moderate but warrants timely remediation to avoid potential escalation. Organizations involved in critical infrastructure, finance, or government sectors may face higher risks due to the sensitivity of their codebases and regulatory requirements around data protection and software integrity.

CWE-272Least Privilege Violation (opens in a new tab)
Base weakness
The elevated privilege level required to perform operations such as chroot() should be dropped immediately after the operation is performed.
Architecture and Design · Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Architecture and Design · Separation of Privilege
Follow the principle of least privilege when assigning access rights to entities in a software system.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
