Sensitive-memory disclosure via uninitialized pointer access
Published Apr 14, 2026 · Updated Apr 14, 2026
Access of uninitialized pointer in Adobe FrameMaker 2022.8 and earlier allows attackers to disclose memory via a crafted XLSX file. Adobe identifies XLSX parsing as the trigger but has not published the affected parser routine or how the uninitialized pointer produces an observable memory read. Exploitation is local and unauthenticated but requires a user to open the malicious file; the reported impact is limited to sensitive-memory disclosure.

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.
