Published: 14 April 2026
Summary
CVE-2026-27311 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-16 (Memory Protection) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-27311 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.
The vulnerability has 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). Exploitation requires local access with no privileges and user interaction, as a victim must open a malicious file crafted by an attacker to trigger the buffer overflow and achieve arbitrary code execution.

Directly mitigates the heap-based buffer overflow in Adobe Bridge by requiring timely patching as detailed in Adobe's security bulletin APSB26-39.
Implements memory protections such as DEP and ASLR that prevent arbitrary code execution from successful heap buffer overflow exploitation.
Requires validation of file inputs to block malformed files that trigger the buffer overflow vulnerability upon opening in Adobe Bridge.
