CVE-2025-29010 is a Missing Authorization vulnerability (CWE-862) identified in the eleopard Behance Portfolio Manager product, affecting versions up to 1.7.4. This vulnerability arises from incorrectly configured access control security levels, allowing users with limited privileges (requiring at least some level of authentication) to perform actions or access resources beyond their authorized scope. The CVSS 3.1 base score is 4.3 (medium severity), with the vector indicating that the attack can be performed remotely over the network (AV:N), requires low complexity (AC:L), requires privileges (PR:L), does not require user interaction (UI:N), and impacts integrity but not confidentiality or availability (C:N/I:L/A:N). Essentially, an authenticated user with limited privileges can exploit this flaw to modify or manipulate data or functionality they should not have access to, potentially leading to unauthorized changes within the Behance Portfolio Manager environment. No known exploits are currently reported in the wild, and no patches or fixes have been linked yet. The vulnerability was reserved in March 2025 and published in June 2025, indicating recent discovery and disclosure. The lack of confidentiality or availability impact suggests the vulnerability primarily threatens data integrity within the application, which could affect the trustworthiness of portfolio data or user-generated content managed by the software.

For European organizations using eleopard Behance Portfolio Manager, this vulnerability could lead to unauthorized modification of portfolio data or user content, undermining data integrity and potentially damaging reputations or client trust. Organizations relying on this software for managing creative portfolios or client projects may face risks of data tampering, which could disrupt workflows or lead to misinformation. While the vulnerability does not directly expose confidential data or cause service outages, the integrity compromise could have downstream effects such as incorrect project representations or unauthorized changes that affect business decisions. Given the medium severity and the requirement for authenticated access, the threat is more relevant to insider threats or compromised user accounts rather than external unauthenticated attackers. European companies in creative industries, marketing agencies, or digital portfolio management sectors using this product should be particularly vigilant. Additionally, regulatory frameworks like GDPR emphasize data integrity and protection, so any unauthorized data manipulation could have compliance implications if personal data or client information is involved.

Since no official patches are currently available, European organizations should implement compensating controls immediately. These include: 1) Restricting user privileges strictly on a need-to-access basis to minimize the number of users with elevated permissions; 2) Enhancing monitoring and logging of user actions within the Behance Portfolio Manager to detect unauthorized modifications promptly; 3) Conducting regular audits of portfolio data integrity to identify suspicious changes; 4) Implementing multi-factor authentication (MFA) to reduce the risk of compromised accounts being used to exploit this vulnerability; 5) Isolating the Behance Portfolio Manager environment within secure network segments to limit exposure; 6) Preparing incident response plans specific to unauthorized data modification scenarios; and 7) Engaging with the vendor (eleopard) for updates or patches and applying them as soon as they become available. Additionally, organizations should educate users about the risks of privilege misuse and enforce strict access control policies.
