Process-memory disclosure via unchecked EMF bitmap offset
Published Mar 17, 2026 · Updated Mar 17, 2026
Out-of-bounds read in Canva Affinity before 3.1.0 allows attackers to disclose process memory through a crafted EMF file. The EMR_STRETCHBLT parser adds an unchecked offBmiSrc offset to the record base even when it exceeds recordSize, then dereferences the resulting address. Exploitation requires a local user to open the file; the access violation can crash the application and disclose arbitrary memory from its process.

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?
