CVE-2026-27293: Adobe Framemaker | Heap-based Buffer Overflow (CWE-122)

Adobe Framemaker versions 2022.8 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.

Security readout for executives and security teams

Plain-English summary

A malicious FrameMaker document can corrupt memory and potentially run attacker-controlled code with the victim’s permissions. An attacker must persuade a user to open the file, making document delivery and user behavior central to the risk.

Executive priority

Prioritize remediation for exposed authoring workstations and privileged users. Treat as high priority because opening one malicious document could compromise confidentiality, integrity, and availability, although no active exploitation is established in the supplied sources.

Technical view

CVE-2026-27293 is a heap-based buffer overflow (CWE-122) in Adobe FrameMaker 2022.8 and earlier. Successful exploitation may achieve arbitrary code execution as the current user. CVSS 3.1 rates it 7.8: local attack vector, low complexity, no privileges required, and required user interaction.

Likely exposure

Exposure is concentrated on endpoints running FrameMaker 2022.8 or earlier, particularly where users receive or open files from external or untrusted sources. Accounts with elevated permissions increase potential impact. The supplied version data should be confirmed against Adobe’s advisory.

Exploitation context

The victim must open a malicious file. The source bundle does not identify public exploit code, observed attacks, or CISA KEV inclusion. Therefore, active exploitation is not established by the supplied evidence.

Researcher notes

The CVSS vector is AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. The supplied description names 2022.8 and earlier, while structured affected data references an upper boundary of 2022.9; validate exact version semantics with APSB26-36. No indicators, exploit maturity details, or technical root-cause analysis are provided.

Mitigation direction

  • Inventory FrameMaker installations and identify versions 2022.8 or earlier.
  • Review APSB26-36 and apply Adobe’s specified update or remediation.
  • Prevent users from opening unexpected FrameMaker files from untrusted sources.
  • Use least-privileged accounts to limit the impact of code execution.
  • Strengthen email and web controls for suspicious document delivery.

Validation and detection

  • Confirm installed FrameMaker versions using endpoint or software inventory records.
  • Verify Adobe’s prescribed remediation is installed on every affected endpoint.
  • Test that untrusted FrameMaker files are blocked or appropriately isolated.
  • Review endpoint alerts involving FrameMaker and suspicious child processes or file activity.
  • Confirm users operating FrameMaker do not routinely hold administrative privileges.
