CVE-2025-61845 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe Format Plugins versions 1.1.1 and earlier. This vulnerability arises when the plugin processes specially crafted files, causing it to read memory beyond the intended buffer boundaries. Such out-of-bounds reads can lead to the exposure of sensitive information residing in adjacent memory areas, potentially including credentials, cryptographic keys, or other confidential data. The vulnerability requires user interaction, meaning an attacker must convince a victim to open a maliciously crafted file, which triggers the vulnerable code path. The CVSS 3.1 base score is 5.5, reflecting a medium severity level with the vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N. This indicates local attack vector, low attack complexity, no privileges required, user interaction needed, unchanged scope, high confidentiality impact, and no impact on integrity or availability. No known exploits have been reported in the wild, and no official patches have been published yet. The vulnerability affects all versions up to 1.1.1, and organizations using Adobe Format Plugins in document processing or content rendering should be aware of the risk. The primary risk is sensitive data leakage through memory disclosure, which could facilitate further attacks or data breaches if exploited successfully.

For European organizations, the primary impact is the potential disclosure of sensitive information stored in memory when a user opens a malicious file processed by Adobe Format Plugins. This could include intellectual property, personal data protected under GDPR, or authentication tokens. Such data exposure could lead to privacy violations, regulatory penalties, and reputational damage. Sectors heavily reliant on document processing, such as finance, legal, government, and healthcare, are particularly vulnerable. Since exploitation requires user interaction, phishing or social engineering campaigns could be used to deliver malicious files. Although there is no direct impact on system integrity or availability, the confidentiality breach could serve as a stepping stone for more sophisticated attacks. The absence of known exploits reduces immediate risk, but the medium severity score and lack of patches mean organizations should proactively mitigate exposure. Failure to address this vulnerability could result in data breaches with compliance and operational consequences.

1. Restrict the acceptance and opening of files from untrusted or unknown sources, especially those processed by Adobe Format Plugins. 2. Educate users to recognize and avoid opening suspicious or unexpected files, particularly from email attachments or downloads. 3. Implement application whitelisting or sandboxing to isolate the Adobe Format Plugins and limit their access to sensitive memory areas. 4. Monitor endpoint and network activity for unusual file access patterns or attempts to open malformed files. 5. Employ Data Loss Prevention (DLP) solutions to detect and block unauthorized data exfiltration that could result from memory disclosure. 6. Stay informed about Adobe’s security advisories and apply patches promptly once available. 7. Consider disabling or limiting the use of Adobe Format Plugins if they are not essential to business operations. 8. Use endpoint detection and response (EDR) tools to detect exploitation attempts or anomalous behavior related to this vulnerability. These measures go beyond generic advice by focusing on user behavior, file handling policies, and proactive monitoring tailored to the nature of this vulnerability.
