CVE-2026-75656: Adobe Bridge Information Disclosure Flaw

CVE-2026-75656 Overview

CVE-2026-75656 is an out-of-bounds read vulnerability in Adobe Bridge that can disclose sensitive process memory. The flaw is classified as [CWE-125] (Out-of-Bounds Read) and requires user interaction to trigger. An attacker crafts a malicious file and convinces a victim to open it in Adobe Bridge. Successful exploitation returns memory contents outside the intended buffer boundaries, potentially exposing credentials, pointers, or other sensitive data resident in the process address space. The issue is local in scope and does not permit code execution or data modification on its own, but the disclosed memory may aid in bypassing mitigations such as Address Space Layout Randomization (ASLR).

Critical Impact
An attacker who tricks a user into opening a crafted file in Adobe Bridge can read sensitive process memory, enabling information disclosure and supporting follow-on exploitation.

Technical Details for CVE-2026-75656

Vulnerability Analysis

The vulnerability is an out-of-bounds read within Adobe Bridge file parsing logic. When Bridge processes a malformed file, an index or length calculation permits a read that crosses the end of an allocated buffer. The resulting read exposes adjacent process memory to logic that returns, renders, or otherwise makes the data observable to the attacker. Because the affected code path executes with the privileges of the invoking user, the disclosure is bounded by the Bridge process context. The impact is confined to confidentiality: integrity and availability of the target system are not directly affected by this defect.

Root Cause

The root cause is missing or insufficient bounds validation in a Bridge file parser. A field within the malicious file drives a read past the end of the parsed structure or buffer. This is a classic [CWE-125] pattern in binary format handlers where a size or offset field is trusted without cross-checking against the actual allocation.

Attack Vector

Exploitation requires local user interaction. The attacker delivers a crafted file through email, a shared drive, a download, or another distribution channel. When the victim opens or previews the file in Adobe Bridge, the vulnerable parser executes and leaks memory. No network access to the target is required, and no elevated privileges are needed to launch the attack.

No public proof-of-concept, exploit code, or in-the-wild exploitation has been reported at the time of publication. See Adobe Security Advisory APSB26-148 for vendor technical details.

Detection Methods for CVE-2026-75656

Indicators of Compromise

Adobe Bridge process crashes or abnormal terminations correlated with opening unfamiliar files
Files with Bridge-associated extensions arriving from untrusted email senders or external file shares
Unexpected child processes spawned by Bridge.exe following file open events
Bridge process reading files from user download or temporary directories immediately before a crash event

Detection Strategies

Monitor endpoint telemetry for Adobe Bridge process crashes and Windows Error Reporting (WER) entries referencing access violations
Alert on Bridge opening files sourced from browser downloads, email attachments, or removable media
Correlate file-open events with subsequent memory-read anomalies or exception codes such as 0xC0000005
Apply YARA or format-inspection rules to attachments delivered to workstations running Adobe Bridge

Monitoring Recommendations

Enable process and file telemetry on all workstations with Adobe Bridge installed
Track Bridge version inventory to identify hosts still running vulnerable builds
Ingest endpoint, email, and file-sharing logs into a central data lake for cross-source correlation
Review user reports of unexpected Bridge behavior after opening files from external sources

How to Mitigate CVE-2026-75656

Immediate Actions Required

Apply the Adobe Bridge security update referenced in APSB26-148 to all affected endpoints
Identify hosts running Adobe Bridge through software inventory and prioritize patch deployment
Instruct users to avoid opening Bridge-associated files received from untrusted or unverified sources
Restrict Adobe Bridge to systems that require it as part of production workflow

Patch Information

Adobe has published a security update for Bridge as documented in Adobe Security Advisory APSB26-148. Administrators should consult the advisory for the fixed version numbers and download locations, then deploy the update through their standard software distribution mechanism.

Workarounds

Block or quarantine Bridge-associated file types at the email gateway when not required for business operations
Use application allow-listing to prevent Adobe Bridge from launching on hosts that do not need it
Enforce least-privilege user accounts so any memory disclosure is limited to non-privileged process context
Educate users on the risks of opening unsolicited creative asset files
