CVE-2026-75676: 
Adobe Bridge vulnerability analysis and mitigation

CVE-2026-75676 is a Stack-based Buffer Overflow vulnerability (CWE-121) in Adobe Bridge that could result in arbitrary code execution in the context of the current user. It affects Adobe Bridge versions up to and including 15.1.7 (15.x branch) and 16.0.6 (16.x branch). The vulnerability was published on September 22, 2026, with a patch made available the same day. It carries a CVSS v3.1 base score of 7.8 (High) (GitHub Advisory, Adobe Advisory).

The vulnerability is classified as CWE-121 (Stack-based Buffer Overflow), where a buffer allocated on the stack is overwritten due to insufficient bounds checking during file parsing operations in Adobe Bridge. An attacker exploits this by crafting a malicious file that, when opened by a victim, triggers the overflow and overwrites adjacent stack memory, potentially redirecting execution flow to attacker-controlled code. The attack vector is local, requires no privileges, but does require user interaction — specifically, the victim must open the malicious file. No public proof-of-concept code has been identified at this time (GitHub Advisory, Adobe Advisory).

Successful exploitation allows an unauthenticated local attacker to execute arbitrary code with the privileges of the current user, resulting in high confidentiality, integrity, and availability impact on the affected system. An attacker could read sensitive files, modify or delete data, or cause the application to crash. Since code execution occurs in the context of the current user, the blast radius is limited to that user's permissions, though it could serve as a stepping stone for privilege escalation in a broader attack chain (GitHub Advisory).

There is no evidence of active in-the-wild exploitation or a publicly available proof-of-concept for CVE-2026-75676 at this time. The NVD SSVC assessment confirms exploitation status as "none" and notes the attack is not automatable due to the required user interaction. The EPSS score is approximately 0.337%, placing it in a low probability tier for near-term exploitation. The vulnerability has not been added to the CISA Known Exploited Vulnerabilities (KEV) catalog. Qualys has added detection for this vulnerability (detection ID 388808) (GitHub Advisory).

1. Craft a malicious file: Create a specially crafted file (e.g., an image or media file supported by Adobe Bridge) that contains oversized or malformed data in a field parsed by the vulnerable code path, designed to overflow a stack-allocated buffer.
2. Deliver the file to the victim: Use social engineering, phishing, or place the file in a shared directory accessible to the target user to induce them to open it with Adobe Bridge.
3. Trigger the overflow: When the victim opens the malicious file in Adobe Bridge, the application processes the malformed input without adequate bounds checking, causing a stack-based buffer overflow.
4. Redirect execution: The overflow overwrites the return address or function pointer on the stack with an attacker-controlled value, redirecting program execution to a shellcode payload or ROP chain embedded in the file.
5. Achieve code execution: Arbitrary code executes in the context of the current user, enabling actions such as dropping additional malware, exfiltrating data, or establishing persistence (GitHub Advisory).

• Process: Unexpected child processes spawned by Adobe Bridge (e.g., cmd.exe, powershell.exe, bash, curl, wget) following the opening of an external file.
• File System: Presence of unusual or newly created executable files, scripts, or DLLs in the user's temp directory or Adobe Bridge installation path shortly after opening a suspicious file.
• Logs: Application crash logs or Windows Error Reporting entries referencing Adobe Bridge with stack corruption or access violation errors tied to file parsing.
• Network: Unexpected outbound network connections originating from the Adobe Bridge process (Bridge.exe) to external IP addresses, particularly after opening a file from an untrusted source.

Adobe has released patched versions addressing this vulnerability: 15.1.8 for the 15.x branch and 16.0.7 for the 16.x branch. Users should update Adobe Bridge immediately via the Creative Cloud desktop application or Adobe's official download channels. As an interim workaround, avoid opening files from untrusted or unknown sources, and consider restricting access to Adobe Bridge in high-security environments until patching is complete (Adobe Advisory, GitHub Advisory).

The Center for Internet Security (CIS) issued an advisory noting that multiple vulnerabilities in Adobe products, including this one, could allow for arbitrary code execution (CIS Advisory). AusCERT also published a bulletin (ESB-2026.11485) covering the Adobe Bridge security update. General community reaction has been measured, consistent with the low EPSS score and absence of active exploitation or public PoC.
