CVE-2025-54238 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe Dimension versions 4.1.3 and earlier. This vulnerability arises when the software improperly handles memory boundaries, allowing an attacker to read memory outside the intended buffer. Exploitation requires user interaction, specifically that the victim opens a maliciously crafted file in Adobe Dimension. Successful exploitation can lead to disclosure of sensitive memory contents, potentially exposing confidential information such as cryptographic keys, passwords, or other sensitive data residing in adjacent memory. The vulnerability does not allow modification of data or denial of service but compromises confidentiality. The CVSS v3.1 base score is 5.5 (medium severity), reflecting that the attack vector is local (AV:L), requires low attack complexity (AC:L), no privileges (PR:N), user interaction (UI:R), and impacts confidentiality (C:H) without affecting integrity or availability. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability was publicly disclosed on August 12, 2025.

For European organizations using Adobe Dimension, particularly those in creative industries, marketing, and design sectors, this vulnerability poses a risk of sensitive information leakage. Since exploitation requires opening a malicious file, targeted spear-phishing or supply chain attacks could be vectors. Disclosure of sensitive memory could lead to exposure of intellectual property, user credentials, or other confidential data, potentially facilitating further attacks or data breaches. Although the impact is limited to confidentiality and does not affect system integrity or availability, the exposure of sensitive data can have regulatory implications under GDPR, especially if personal data is involved. The medium severity rating suggests moderate risk, but organizations with high-value assets or sensitive projects should treat this vulnerability seriously.

Organizations should implement the following specific mitigations: 1) Educate users to avoid opening files from untrusted or unknown sources in Adobe Dimension. 2) Employ strict email filtering and endpoint security solutions to detect and block malicious files targeting Adobe Dimension. 3) Monitor for updates from Adobe and apply patches promptly once released. 4) Use application whitelisting to restrict execution of unauthorized files within Adobe Dimension. 5) Conduct regular audits of systems running Adobe Dimension to detect unusual file access or memory usage patterns. 6) Consider isolating systems running Adobe Dimension in segmented network zones to limit lateral movement if exploitation occurs. 7) Implement Data Loss Prevention (DLP) controls to monitor and prevent unauthorized exfiltration of sensitive data that could result from memory disclosure.
