Summary
CVE-2026-27310 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 0.9th 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-16 (Memory Protection) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly remediates the heap-based buffer overflow vulnerability in Adobe Bridge through timely identification, testing, and application of vendor security patches.
Implements system memory protections such as ASLR, DEP, and heap canaries to prevent arbitrary code execution resulting from the heap-based buffer overflow.
Deploys malicious code protection mechanisms to scan and block malicious files that exploit the buffer overflow when opened in Adobe Bridge.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Heap buffer overflow in client application (Adobe Bridge) enables arbitrary code execution upon opening a malicious file, directly mapping to client-side exploitation and user-executed malicious file techniques.

Deeper analysisAI
CVE-2026-27310 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, this flaw could result in arbitrary code execution in the context of the current user.
Exploitation requires local access (AV:L) with low complexity (AC:L) and no privileges (PR:N), but user interaction is necessary as the victim must open a malicious file (UI:R). Successful exploitation allows an attacker to achieve high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) within the same security scope (S:U), earning a CVSS 3.1 base score of 7.8.
