Adobe Bridge Untrusted Search Path Vulnerability Allows Arbitrary Code Execution (CVE-2026-48395)

Adobe has disclosed a high-severity Untrusted Search Path vulnerability, identified as CVE-2026-48395, affecting Adobe Bridge versions up to and including 16.0.5 and 15.1.6. This flaw allows an attacker to achieve arbitrary code execution on a victim's system. The exploitation requires user interaction, specifically convincing a user to open a malicious file. If successfully exploited, the attacker's code would execute with the same privileges as the logged-in user, potentially leading to system compromise, data theft, or further lateral movement within an organization. While the vulnerability description does not provide details on observed exploitation in the wild, the nature of arbitrary code execution makes it a significant risk for users of affected Adobe Bridge versions. Organizations using Adobe Bridge should prioritize patching to mitigate this threat.

Attack Chain

1. An attacker crafts a malicious file designed to exploit the Untrusted Search Path vulnerability (CWE-426) in Adobe Bridge.
2. The attacker delivers this malicious file to a victim, typically via social engineering tactics such as email or instant message, or by hosting it on a compromised website.
3. The victim is convinced to open the malicious file using an affected version of Adobe Bridge.
4. Upon opening the file, Adobe Bridge attempts to load required libraries or components from an untrusted or manipulated search path.
5. The malicious file redirects Adobe Bridge to load an attacker-controlled library or executable.
6. The attacker's arbitrary code is executed on the victim's system under the context of the current user.
7. The attacker gains control over the user's environment, potentially leading to further compromise, data exfiltration, or system modification.

Impact

Successful exploitation of CVE-2026-48395 would lead to arbitrary code execution in the context of the current user. This means an attacker could perform actions such as installing malware, modifying or deleting data, or creating new user accounts with the same rights as the victim. The primary limitation to exploitation is the requirement for user interaction, as a victim must be tricked into opening a malicious file. While no specific victim counts or targeted sectors are mentioned, any organization or individual using vulnerable versions of Adobe Bridge is at risk of local system compromise if exposed to a malicious file.

Recommendation

• Patch CVE-2026-48395 immediately by updating Adobe Bridge to a version greater than 16.0.5 or 15.1.6 as per the vendor advisory available at https://helpx.adobe.com/security/products/bridge/apsb26-89.html.
• Educate users about the dangers of opening untrusted files, particularly those received from unknown or suspicious sources, to mitigate the user interaction requirement described in the CVE-2026-48395.
