CVE-2025-58335 is a medium-severity vulnerability affecting JetBrains Junie versions prior to 252.284.66, 251.284.66, 243.284.66, 252.284.61, 251.284.61, 243.284.61, 252.284.50, 252.284.54, 251.284.54, 251.284.50, 243.284.54, and 243.284.50. The vulnerability is categorized under CWE-356, which relates to 'Incorrect Handling of Sensitive Information'. Specifically, the flaw exists in the search_project function of JetBrains Junie, where it allows unauthorized information disclosure. This means that an attacker with local access and high attack complexity can, through user interaction, exploit this vulnerability to gain access to sensitive information that should otherwise be protected. The CVSS 3.1 vector (AV:L/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N) indicates that the attack requires local access (AV:L), high complexity (AC:H), no privileges (PR:N), and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality is high (C:H), but there is no impact on integrity (I:N) or availability (A:N). No known exploits are currently reported in the wild, and no patches or mitigations are linked yet. The vulnerability allows an attacker to disclose sensitive data via the search_project function, potentially exposing project details or other confidential information handled by JetBrains Junie. Given the nature of the vulnerability, it is likely to affect environments where JetBrains Junie is used for project management or development tasks, especially in local or internal network contexts.

For European organizations, this vulnerability poses a risk of sensitive information leakage within development environments using JetBrains Junie. The exposure of confidential project data could lead to intellectual property theft, leakage of proprietary code, or exposure of sensitive business information. This could undermine competitive advantage and lead to compliance issues, especially under GDPR if personal data is involved. Since the attack requires local access and user interaction, the threat is more significant in environments with less strict endpoint security or where social engineering could be used to trick users into triggering the vulnerability. Organizations with distributed development teams or those using Junie on shared or less secure devices may face increased risk. The confidentiality breach could also facilitate further attacks by providing attackers with insights into project structure or internal processes. However, the lack of impact on integrity and availability limits the threat to data exposure rather than system disruption or data manipulation.

European organizations should implement strict access controls to limit local access to systems running JetBrains Junie, ensuring only authorized personnel can interact with the software. Endpoint security solutions should be enhanced to detect and prevent social engineering attempts that could lead to user interaction exploitation. Monitoring and logging of search_project function usage could help detect anomalous behavior indicative of exploitation attempts. Until official patches are released, organizations should consider restricting or disabling the search_project functionality if feasible, or isolate systems running vulnerable versions in secure network segments. Regular user training on phishing and social engineering risks can reduce the likelihood of successful exploitation. Additionally, organizations should maintain an inventory of JetBrains Junie versions in use and plan prompt updates once patches become available. Employing application whitelisting and privilege management can further reduce the attack surface by limiting the ability of unauthorized users to execute or interact with vulnerable components.
