CVE-2026-100126: 
Adobe Bridge vulnerability analysis and mitigation

CVE-2026-100126 is an out-of-bounds read vulnerability (CWE-125) in Adobe Bridge that can lead to disclosure of sensitive memory contents. Affected versions include Adobe Bridge 15.x up to and including 15.1.8, and 16.x up to and including 16.0.7. The vulnerability was published on October 13, 2026, and assigned by Adobe's PSIRT. It carries a CVSS v3.1 base score of 5.5 (Medium) (Adobe Advisory, ENISA EUVD).

The vulnerability is classified as CWE-125 (Out-of-bounds Read), mapped to CAPEC-540 (Overread Buffers). An attacker exploits this by crafting a malicious file that, when opened by a victim in Adobe Bridge, triggers an out-of-bounds memory read operation. 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 or detailed technical write-up has been identified at this time (Adobe Advisory).

Successful exploitation results in the disclosure of sensitive memory contents from the affected system, impacting confidentiality. There is no impact to integrity or availability based on the CVSS assessment. The scope is limited to the local system running the vulnerable Adobe Bridge instance, with no known potential for lateral movement directly from this vulnerability (Adobe Advisory).

No public proof-of-concept exploit code has been identified, and there is no evidence of in-the-wild exploitation at this time. The EPSS score is reported as 0.0, indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Exploitation requires social engineering to convince a victim to open a specially crafted file (ENISA EUVD).

1. Craft malicious file: An attacker creates a specially crafted file (e.g., an image or media file supported by Adobe Bridge) designed to trigger an out-of-bounds read when parsed by the application.
2. Deliver the file: The attacker delivers the malicious file to the target via phishing email, malicious download link, or other social engineering methods.
3. Victim opens the file: The victim opens the malicious file using a vulnerable version of Adobe Bridge (≤15.1.8 or ≤16.0.7), triggering the out-of-bounds read.
4. Memory disclosure: The vulnerability causes Adobe Bridge to read beyond the intended buffer boundary, exposing sensitive memory contents that may include credentials, tokens, or other in-memory data.
5. Exfiltrate data: If the attacker can observe the application's output or crash dumps (e.g., via a secondary vulnerability or controlled environment), they may extract the disclosed memory contents (Adobe Advisory).

Adobe has released patched versions to address this vulnerability: Adobe Bridge 15.1.9 (for the 15.x branch) and Adobe Bridge 16.0.8 (for the 16.x branch). Users should update to these versions or later as soon as possible via the Creative Cloud desktop application or Adobe's official download channels. No configuration-based workarounds have been published; upgrading is the recommended remediation (Adobe Advisory).

The vulnerability received limited public attention, with automated CVE tracking services (VulnDB, CVEFeed, Radar Offseq) publishing entries shortly after disclosure. No notable independent researcher commentary or significant media coverage has been identified beyond standard vulnerability aggregation (VulnDB).
