Which versions of Bridge are affected by CVE-2026-27311?

Adobe Bridge versions 16.0.2, 15.1.4, and earlier contain a heap-based buffer overflow that allows arbitrary code execution when users open malicious files, potentially compromising sensitive…

How to fix or mitigate CVE-2026-27311?

Within 24 hours: Inventory all Adobe Bridge deployments (versions 16.0.2, 15.1.4, and earlier) across the organization and restrict user access to untrusted files. Within 7 days: Disable or uninstall Adobe Bridge if not critical; if required, implement application whitelisting and monitor file access logs for suspicious activity. Within 30 days: Monitor Adobe security advisory APSB26-39 for patch release and apply immediately upon availability; in parallel, evaluate alternative design software without this vulnerability.

HIGH 7.8

DescriptionCVE.org

Bridge versions 16.0.2, 15.1.4 and earlier are affected by a Heap-based Buffer Overflow vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

AnalysisAI

Heap-based buffer overflow in Adobe Bridge 16.0.2, 15.1.4, and earlier versions enables arbitrary code execution with user privileges when processing maliciously crafted files. CVSS 7.8 reflects high impact across confidentiality, integrity, and availability, requiring local access and user interaction. CISA SSVC framework categorizes this as non-automatable with total technical impact. No public exploit identified at time of analysis, and vendor has released security advisory APSB26-39 addressing the vulnerability.

Technical ContextAI

Adobe Bridge is a digital asset management application used extensively in creative workflows for organizing and browsing media files. This vulnerability (CWE-122) stems from improper bounds checking when parsing file formats, allowing heap memory corruption. When Bridge processes a specially crafted file, attacker-controlled data overflows a dynamically allocated buffer on the heap, overwriting adjacent memory structures. This memory corruption can be leveraged to redirect program execution flow, enabling arbitrary code execution. The vulnerability affects Bridge versions 15.x through 15.1.4 and the 16.0.x branch through 16.0.2, indicating the flaw exists in core file parsing routines shared across multiple release branches.

RemediationAI

Apply vendor-released security updates as documented in Adobe Security Bulletin APSB26-39 immediately. Organizations should upgrade to the patched versions specified in the bulletin, which addresses the heap overflow vulnerability through improved bounds checking in file parsing routines. Until patches are deployed, implement defense-in-depth controls including restricting Bridge usage to trusted file sources only, disabling automatic file previews if configurable, and educating users not to open Bridge files from unknown or untrusted sources. Security teams should prioritize patching for systems processing files from external partners, email attachments, or public file repositories. Verify successful patch deployment by confirming Bridge version numbers post-update through the application's About menu.
