Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly requires timely identification, reporting, and correction of the heap-based buffer overflow flaw in Adobe Bridge, preventing arbitrary code execution from malicious files.

prevent

Implements memory protection mechanisms such as DEP and ASLR to block unauthorized code execution resulting from the heap buffer overflow vulnerability.

detect

Enables vulnerability scanning to identify systems with vulnerable Adobe Bridge versions, supporting rapid remediation before exploitation.

MITRE ATT&CK Enterprise TechniquesAI

T1203 Exploitation for Client Execution Execution
Adversaries may exploit software vulnerabilities in client applications to execute code.
Why these techniques?

Heap buffer overflow in client application (Adobe Bridge) enables arbitrary code execution upon opening a malicious file, directly mapping to Exploitation for Client Execution (T1203).

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

Deeper analysisAI

CVE-2026-27313 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 issue carries a CVSS v3.1 base score of 7.8 (High: AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high impact on confidentiality, integrity, and availability upon successful exploitation.

Exploitation requires local access with low complexity and no privileges, but user interaction is necessary as the victim must open a malicious file. A successful attack enables arbitrary code execution in the context of the current user.
