CVE-2025-54233 is a medium-severity vulnerability identified in Adobe FrameMaker versions 2020.8, 2022.6, and earlier. The vulnerability is classified as an out-of-bounds read (CWE-125), which occurs when the software reads data outside the bounds of allocated memory. This flaw can lead to the disclosure of sensitive memory contents, potentially exposing confidential information to an attacker. Exploitation requires user interaction, specifically that the victim opens a maliciously crafted FrameMaker file. The CVSS v3.1 base score is 5.5, reflecting a local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). There are no known exploits in the wild at the time of publication, and no patches have been linked yet. The vulnerability arises from improper bounds checking during file parsing, which can cause the application to read memory beyond the intended buffer, leaking sensitive data that may reside in adjacent memory regions. This type of vulnerability is particularly concerning in environments where sensitive or proprietary information is processed or stored within FrameMaker documents or memory during editing.

For European organizations, the impact of CVE-2025-54233 could be significant in sectors that rely heavily on Adobe FrameMaker for technical documentation, publishing, or content management, such as aerospace, automotive, manufacturing, and government agencies. The disclosure of sensitive memory contents could lead to leakage of confidential business information, intellectual property, or personally identifiable information (PII), depending on what data resides in memory at the time of exploitation. Although the vulnerability does not allow code execution or system compromise, the confidentiality breach could facilitate further targeted attacks or corporate espionage. The requirement for user interaction (opening a malicious file) limits the attack vector primarily to social engineering or phishing campaigns targeting employees with access to FrameMaker. Organizations with strict document handling policies and security awareness training may reduce risk, but those with less mature security postures could be vulnerable to data leaks. Additionally, the lack of a patch at the time of disclosure means organizations must rely on interim mitigations to reduce exposure.

To mitigate CVE-2025-54233, European organizations should implement the following specific measures: 1) Restrict usage of Adobe FrameMaker to trusted users and environments, minimizing exposure to untrusted files. 2) Enforce strict email and file attachment filtering to block or quarantine suspicious FrameMaker files from unknown or untrusted sources. 3) Conduct targeted user awareness training emphasizing the risks of opening unsolicited or unexpected FrameMaker documents. 4) Utilize application whitelisting and sandboxing techniques to isolate FrameMaker processes, limiting potential data exposure. 5) Monitor and audit FrameMaker usage logs for unusual file access patterns or user behavior indicative of phishing or social engineering attempts. 6) Coordinate with Adobe for timely patch deployment once available, and apply updates promptly. 7) Consider deploying endpoint detection and response (EDR) solutions capable of detecting anomalous memory access or file parsing behaviors related to FrameMaker. 8) Implement data loss prevention (DLP) controls to detect and prevent unauthorized exfiltration of sensitive information that could result from exploitation.
