CVE-2025-61841 is a medium severity vulnerability classified as an out-of-bounds read (CWE-125) affecting Adobe Format Plugins versions 1.1.1 and earlier. The vulnerability arises when the plugin processes specially crafted files that cause it to read memory beyond the intended buffer boundaries. This can lead to exposure of sensitive information residing in adjacent memory areas, potentially leaking confidential data. Exploitation requires the victim to open a malicious file, meaning user interaction is necessary, and no elevated privileges or prior authentication are required. The vulnerability impacts confidentiality (C:H) but does not compromise integrity or availability. The attack vector is local (AV:L), indicating that the attacker must have some means to deliver the malicious file to the victim, such as via email or file sharing. The vulnerability was reserved on October 1, 2025, and published on November 11, 2025. There are currently no known exploits in the wild, and Adobe has not yet released patches or mitigations. Given Adobe's widespread use in document processing and content creation, this vulnerability could be leveraged in targeted attacks to extract sensitive information from affected systems. The lack of integrity or availability impact reduces the risk of destructive attacks but still poses a significant privacy concern.

For European organizations, this vulnerability poses a risk of sensitive data leakage when users open malicious files containing crafted content targeting Adobe Format Plugins. Industries such as finance, legal, government, and media, which heavily rely on Adobe products for document handling, are particularly at risk. Exposure of confidential information could lead to data breaches, regulatory non-compliance (e.g., GDPR violations), and reputational damage. Since exploitation requires user interaction, phishing or social engineering campaigns could be used to deliver malicious files. The medium severity rating reflects a moderate risk; however, the potential for sensitive data exposure makes it a concern for organizations handling personal or proprietary information. The absence of known exploits currently provides a window for proactive mitigation. The impact is primarily on confidentiality, with no direct effect on system integrity or availability.

1. Immediately implement strict email and file filtering policies to block or quarantine suspicious files that could exploit this vulnerability. 2. Educate users on the risks of opening files from untrusted or unknown sources, emphasizing caution with unexpected attachments. 3. Employ endpoint security solutions capable of detecting anomalous behavior related to Adobe Format Plugins. 4. Monitor Adobe's security advisories closely and apply patches or updates promptly once available. 5. Consider sandboxing or isolating document processing environments to limit exposure if a malicious file is opened. 6. Use data loss prevention (DLP) tools to detect and prevent unauthorized data exfiltration that could result from exploitation. 7. Conduct regular security awareness training focusing on social engineering and phishing tactics that could deliver malicious files. 8. Review and restrict user permissions to minimize the impact scope if exploitation occurs. 9. Maintain up-to-date backups and incident response plans tailored to data leakage scenarios. These measures go beyond generic advice by focusing on user behavior, detection, and containment specific to this vulnerability's exploitation vector.
