CVE-2026-75663: 
Adobe Bridge vulnerability analysis and mitigation

CVE-2026-75663 is an out-of-bounds write vulnerability (CWE-787) 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 (fixed in 15.1.8) and versions 16.0.0 through 16.0.6 (fixed in 16.0.7). 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-787 (Out-of-bounds Write), meaning the application writes data beyond the boundaries of an allocated buffer during the processing of a specially crafted file. Exploitation requires a local attack vector with low complexity and no privileges, but does require user interaction — specifically, a victim must open a malicious file. No public proof-of-concept or detailed technical write-up has been identified at this time (GitHub Advisory, Adobe Advisory).

Successful exploitation allows an attacker to execute arbitrary code with the privileges of the current user, resulting in high confidentiality, integrity, and availability impact. An attacker could read sensitive files accessible to the user, modify or delete data, or cause the application to crash. The scope is limited to the affected system and user context, with no automatic privilege escalation beyond the current user's permissions (GitHub Advisory).

There is no evidence of active in-the-wild exploitation or a publicly available proof-of-concept as of the time of publication. The EPSS score is approximately 0.256% (roughly the 4th percentile), indicating a low near-term probability of exploitation. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, and the SSVC assessment notes it is not automatable due to the required user interaction (GitHub Advisory).

Adobe has released patched versions addressing this vulnerability: users should update to Adobe Bridge 15.1.8 or later (for the 15.x branch) or Adobe Bridge 16.0.7 or later (for the 16.x branch). As an interim measure, users should avoid opening files from untrusted or unknown sources. Applying the vendor patch is the recommended and definitive remediation (Adobe 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 muted given the absence of active exploitation or a public PoC.
