Code execution via malicious file out-of-bounds write
Published Jul 28, 2026 · Updated Jul 28, 2026
Out-of-bounds write in Adobe Bridge 15.1.6 and earlier and 16.0.5 and earlier allows attackers to execute code via a malicious file. Adobe has not disclosed the affected file parser or the bounds-calculation error that causes crafted-file data to be written outside its intended buffer. The victim must open the file, and successful exploitation runs code in the context of the current user on Windows or macOS.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=15.1.6
- Affected versionversion=0 <=16.0.5
