CVE-2025-61841 is a vulnerability classified as an out-of-bounds read (CWE-125) affecting Adobe Format Plugins versions 1.1.1 and earlier. This vulnerability arises when the plugin processes specially crafted files that cause it to read memory outside the intended buffer boundaries. Such out-of-bounds reads can lead to the exposure of sensitive memory contents, potentially leaking confidential information such as cryptographic keys, passwords, or other sensitive data residing in memory. The attack vector requires that a victim user opens a maliciously crafted file, making user interaction mandatory for exploitation. The vulnerability does not allow for code execution or denial of service but compromises confidentiality. The CVSS v3.1 base score is 5.5, reflecting a medium severity with the vector metrics AV:L (local access), AC:L (low complexity), PR:N (no privileges required), UI:R (user interaction required), S:U (unchanged scope), C:H (high confidentiality impact), I:N (no integrity impact), and A:N (no availability impact). There are no known exploits in the wild at the time of publication, and no patches have been linked yet, indicating that remediation may still be pending. The vulnerability is relevant to any environment where Adobe Format Plugins are used to process files, especially in document-heavy workflows. Attackers could leverage this vulnerability to gain unauthorized access to sensitive data in memory, which could be used for further attacks or data exfiltration. The requirement for user interaction and local access somewhat limits the attack surface but does not eliminate risk, particularly in environments where users frequently open files from untrusted sources.

For European organizations, the primary impact of CVE-2025-61841 is the potential exposure of sensitive information residing in memory when processing malicious files with Adobe Format Plugins. This can lead to confidentiality breaches affecting personal data, intellectual property, or credentials, which is critical under GDPR and other data protection regulations. Organizations in sectors such as finance, healthcare, government, and critical infrastructure that rely on Adobe software for document handling are at increased risk. The vulnerability does not directly affect system integrity or availability, so operational disruption is unlikely. However, the leakage of sensitive memory data could facilitate further attacks, including privilege escalation or lateral movement within networks. The requirement for user interaction means that phishing or social engineering campaigns could be used to deliver malicious files, increasing the risk to end users. European entities with strict compliance requirements must consider the reputational and legal consequences of data exposure resulting from this vulnerability.

1. Monitor Adobe security advisories closely and apply patches or updates for Format Plugins as soon as they become available. 2. Until patches are released, restrict the use of Adobe Format Plugins to trusted files only by implementing strict file filtering and validation policies. 3. Employ sandboxing techniques to isolate the processing of untrusted files, minimizing the risk of memory exposure affecting other system components. 4. Use Content Disarm and Reconstruction (CDR) solutions to sanitize incoming files and remove potentially malicious content before they reach end users. 5. Educate users about the risks of opening files from unknown or untrusted sources to reduce the likelihood of successful exploitation. 6. Implement endpoint detection and response (EDR) solutions to monitor for unusual file access or memory read patterns indicative of exploitation attempts. 7. Conduct regular security audits and vulnerability assessments focusing on document processing workflows to identify and remediate similar risks proactively.
