CVE-2025-43547 is a high-severity integer overflow or wraparound vulnerability (CWE-190) affecting Adobe Bridge versions 15.0.3, 14.1.6, and earlier. Adobe Bridge is a digital asset management application widely used for organizing and managing multimedia files. The vulnerability arises when the software improperly handles integer values, leading to an overflow or wraparound condition. This flaw can be exploited by an attacker who crafts a malicious file that, when opened by the victim in Adobe Bridge, triggers the overflow. The consequence of this overflow is the potential for arbitrary code execution within the context of the current user. The CVSS v3.1 base score is 7.8, reflecting high severity, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact on confidentiality, integrity, and availability is rated high, indicating that successful exploitation could lead to full compromise of the affected system under the current user’s permissions. No known exploits are reported in the wild yet, and no patches or updates have been linked at the time of this report. The vulnerability requires the victim to open a malicious file, meaning social engineering or phishing could be used as an attack vector. Because Adobe Bridge is often used by creative professionals and organizations handling large volumes of digital media, this vulnerability could be leveraged to gain footholds in targeted environments.

For European organizations, the impact of CVE-2025-43547 could be significant, especially for industries relying heavily on digital asset management such as media, advertising, publishing, and design firms. Successful exploitation could lead to unauthorized code execution, enabling attackers to steal sensitive data, implant malware, or move laterally within networks. Given that Adobe Bridge runs with user-level privileges, the attacker’s capabilities would initially be limited to the current user context; however, this can still lead to data exfiltration or serve as a stepping stone for privilege escalation. The requirement for user interaction means that phishing or malicious file distribution campaigns could be effective attack vectors. European organizations with remote or hybrid workforces might be particularly vulnerable if users open files received via email or collaboration platforms without sufficient security controls. Additionally, regulatory frameworks such as GDPR impose strict data protection requirements, and a breach resulting from this vulnerability could lead to significant compliance and reputational consequences.

1. Immediate mitigation should focus on user awareness and training to avoid opening untrusted or unexpected files in Adobe Bridge. 2. Implement email and endpoint security solutions capable of detecting and blocking malicious files or suspicious behaviors related to file handling. 3. Employ application whitelisting and sandboxing techniques to limit the execution context of Adobe Bridge and isolate it from sensitive systems. 4. Monitor for unusual process behavior or network activity originating from Adobe Bridge instances. 5. Since no patch is currently available, organizations should consider restricting or disabling Adobe Bridge usage where feasible until a vendor update is released. 6. Use endpoint detection and response (EDR) tools to detect exploitation attempts or post-exploitation activities. 7. Maintain up-to-date backups and incident response plans tailored to potential exploitation scenarios involving user-level code execution vulnerabilities.
