CVE-2021-44743: Adobe Bridge JPEG2000 Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability

Adobe Bridge version 11.1.2 (and earlier) and version 12.0 (and earlier) are affected by an out-of-bounds write 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.

Security readout for executives and security teams

Plain-English summary

Adobe Bridge could be compromised if a user opens a malicious JPEG2000-related file. Successful exploitation could run code as that user, putting files, credentials, and workstation access at risk. The available sources do not show known active exploitation.

Executive priority

Treat this as a high-priority workstation patching issue, especially for creative teams. It requires user interaction, but the impact is full code execution as the current user.

Technical view

CVE-2021-44743 is a CWE-787 out-of-bounds write in Adobe Bridge JPEG2000 parsing. Affected versions are Bridge 11.1.2 and earlier, and 12.0 and earlier. CVSS 3.0 is 7.8 with user interaction required and high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is most likely on endpoints used for creative, marketing, design, or media workflows where Adobe Bridge is installed and users open externally supplied image assets.

Exploitation context

The attacker must convince a user to open a malicious file. The source bundle marks CISA KEV as false, and no provided source states active exploitation.

Researcher notes

The key exposure condition is vulnerable Bridge parsing a malicious file, not network reachability. Evidence in the bundle supports affected versions, CWE-787 classification, CVSS 7.8, and required user interaction; it does not provide exploit indicators or exact fixed build details.

Mitigation direction

  • Apply the Adobe Bridge security update referenced in APSB22-03.
  • Prioritize users who handle third-party media or image submissions.
  • Restrict opening untrusted image files until Bridge is updated.
  • Check Adobe guidance for exact fixed versions and deployment instructions.

Validation and detection

  • Inventory endpoints with Adobe Bridge installed.
  • Confirm whether Bridge is 11.1.2 or earlier, or 12.0 or earlier.
  • Verify update status against Adobe APSB22-03 guidance.
  • Review email, download, and file-sharing workflows for untrusted image handling.

Out-of-bounds Write

Out-of-bounds Write represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
