CVE-2025-61844 is an out-of-bounds read vulnerability classified under CWE-125 found in Adobe Format Plugins version 1.1.1 and earlier. This vulnerability occurs when the plugin improperly handles memory bounds while parsing certain file formats, allowing an attacker to read memory beyond the intended buffer. The consequence is potential exposure of sensitive information residing in adjacent memory areas, which could include credentials, cryptographic keys, or other confidential data. Exploitation requires that a victim user opens a maliciously crafted file processed by the vulnerable Adobe Format Plugins, making user interaction mandatory. The CVSS v3.1 score of 5.5 reflects a medium severity level, with the vector indicating 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 (I:N) or availability (A:N). No public exploits have been reported yet, and no patches are currently linked, suggesting that remediation may be pending or in development. The vulnerability primarily threatens confidentiality by leaking memory contents but does not allow code execution or denial of service. Adobe Format Plugins are components used in various Adobe products to support multiple file formats, so any organization using these products is potentially at risk if users open malicious files. The attack surface is limited to users who handle files from untrusted sources, emphasizing the importance of user awareness and file handling policies.

For European organizations, the primary impact of CVE-2025-61844 is the potential disclosure of sensitive information through memory exposure when users open malicious files. This could lead to leakage of confidential business data, intellectual property, or user credentials, increasing the risk of further compromise or data breaches. Organizations in sectors such as media, design, publishing, and any industry relying heavily on Adobe software are particularly vulnerable. Although the vulnerability does not allow remote exploitation without user interaction, targeted phishing or spear-phishing campaigns could exploit this flaw to gain sensitive information. The medium severity rating indicates a moderate risk, but the confidentiality impact is high, which is critical for compliance with European data protection regulations like GDPR. Failure to mitigate this vulnerability could result in regulatory penalties and reputational damage. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once patches are released or if the vulnerability becomes widely known.

1. Monitor Adobe’s official channels for patches addressing CVE-2025-61844 and apply updates promptly once available. 2. Implement strict file handling policies to restrict opening files from untrusted or unknown sources, especially those processed by Adobe Format Plugins. 3. Educate users about the risks of opening unsolicited or suspicious files and train them to recognize phishing attempts. 4. Employ endpoint protection solutions capable of detecting anomalous behavior related to file parsing or memory access in Adobe applications. 5. Use application whitelisting and sandboxing techniques to isolate Adobe software processes and limit the impact of potential exploitation. 6. Conduct regular audits of software versions deployed across the organization to identify and remediate vulnerable instances. 7. Consider network segmentation to reduce the spread of compromise if sensitive information is leaked. 8. Review and enhance data loss prevention (DLP) controls to detect unusual data exfiltration that could result from memory disclosure. 9. Maintain robust incident response plans to quickly address any exploitation attempts or data leaks related to this vulnerability.
