CVE-2026-27313
Published: 14 April 2026
Summary
CVE-2026-27313 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 8.9th 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 RA-5 (Vulnerability Monitoring and Scanning) and SI-2 (Flaw Remediation).
Deeper analysis
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.
Adobe's security advisory (APSB26-39) at https://helpx.adobe.com/security/products/bridge/apsb26-39.html provides further details on the vulnerability and mitigation steps.
