Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Bridge versions 15.1.2, 16.0 and earlier are affected by a Heap-based Buffer Overflow vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Adobe Bridge versions 15.1.2, 16.0 and earlier contain a heap-based buffer overflow vulnerability during file parsing. An attacker can exploit this by crafting a malicious file that, when opened by a victim, triggers the overflow and allows arbitrary code execution in the context of the current user.

MitigationUpdate Adobe Bridge to the latest patched version. Until patched, avoid opening untrusted or unexpected files in Bridge.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Adobe Bridge is installed
    Check for Bridge.exe in common installation paths such as C:\Program Files\Adobe\Adobe Bridge 2024\Bridge.exe or C:\Program Files\Adobe\Adobe Bridge CC 2021\Bridge.exe. You can also search for 'Adobe Bridge' in Programs and Features or use 'Get-ItemProperty' in PowerShell against the registry key HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Bridge.exe
    Affected if Adobe Bridge is found on the system
  2. Determine the installed Bridge version
    Right-click Bridge.exe, select Properties, and view the Version tab. Alternatively, run ' (Get-Item "C:\Program Files\Adobe\Adobe Bridge 2024\Bridge.exe").VersionInfo.FileVersion' in PowerShell (adjust path to match your installation)
    Affected if The version displayed is 15.1.2 or earlier, or exactly 16.0
  3. Compare against affected version ranges
    Review the version number against the vulnerable ranges: versions less than 15.1.3 (including 15.1.2, 15.1.1, 15.0 and earlier) and version 16.0 specifically are affected
    Affected if Your installed version falls within < 15.1.3 or = 16.0

If Adobe Bridge is installed and the version is either 16.0 or any version below 15.1.3, your environment is vulnerable to this heap-based buffer overflow when processing maliciously crafted files.
