CVE-2026-27312
Published: 14 April 2026
Summary
CVE-2026-27312 is a high-severity Heap-based Buffer Overflow (CWE-122) vulnerability in Adobe Bridge. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 1.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-2 (Flaw Remediation) and AC-6 (Least Privilege).
Deeper analysis
CVE-2026-27312 is a heap-based buffer overflow vulnerability (CWE-122) affecting Adobe Bridge versions 16.0.2, 15.1.4, and earlier. Published on 2026-04-14, the flaw could result in arbitrary code execution in the context of the current user.
With a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), the vulnerability can be exploited by an attacker with local access who requires no privileges but needs user interaction, specifically convincing a victim to open a malicious file. Successful exploitation enables arbitrary code execution, leading to high impacts on confidentiality, integrity, and availability.
Adobe has published security bulletin APSB26-39 at https://helpx.adobe.com/security/products/bridge/apsb26-39.html, which addresses the vulnerability.

Mitigating Controls (NIST 800-53 r5) AI
Directly mitigates the heap-based buffer overflow by requiring timely patching of affected Adobe Bridge versions as specified in security bulletin APSB26-39.
Implements memory protections such as ASLR and DEP that hinder successful exploitation of the heap buffer overflow for arbitrary code execution.
Enforces least privilege on user accounts, limiting the confidentiality, integrity, and availability impacts of code execution in the current user context.
