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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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 2026-10-26.

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

1. Upgrade IntelliJ IDEA to version 2025.3 or later as soon as the patch is released to ensure the missing confirmation prompt is implemented. 2. Until the patch is available, enforce strict policies restricting the opening of remote projects over SSH to trusted sources only. 3. Educate developers and users about the risks of opening untrusted remote projects and encourage verification of project origins before access. 4. Implement network-level controls to limit SSH access to known and verified hosts. 5. Use endpoint security solutions that can detect suspicious activity related to remote project access or code injection attempts. 6. Monitor development environments for unusual behavior or unexpected project openings. 7. Consider using alternative secure development environments or tools that provide explicit confirmation for remote project access if immediate patching is not feasible. 8. Integrate security awareness training focused on social engineering and remote code access risks within development teams.

Description

In JetBrains IntelliJ IDEA before 2025.3 missing confirmation allowed opening of untrusted remote projects over SSH

Impact

For European organizations, this vulnerability poses a risk primarily to software development teams using IntelliJ IDEA for remote project access over SSH. The potential impact includes unauthorized disclosure of sensitive source code or project configurations if malicious remote projects are opened without confirmation. This could lead to intellectual property theft or leakage of confidential business logic. Integrity impacts, while limited, could allow attackers to influence the development environment or inject malicious code if combined with other vulnerabilities or social engineering tactics. The requirement for user interaction reduces the likelihood of automated exploitation but does not eliminate risk, especially in environments with less stringent security awareness. Organizations relying heavily on remote development workflows or using SSH for project access are more vulnerable. The absence of known exploits suggests a window for proactive mitigation. Given the medium severity, the impact is moderate but could escalate if exploited in targeted attacks against critical software projects or intellectual property within European tech sectors.
