CVE-2026-27310
Published: 14 April 2026
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 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-2026-27310 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.
