CVE-2025-64776 is a medium-severity vulnerability classified under CWE-125 (Out-of-bounds Read) affecting the EMF (Enhanced Metafile) functionality in Canva Affinity. The vulnerability arises when the software processes specially crafted EMF files that cause it to read memory beyond the allocated buffer boundaries. This out-of-bounds read can expose sensitive information residing in adjacent memory areas, potentially leaking confidential data. The attack vector is local (AV:L), requiring the attacker to provide a malicious EMF file and the user to interact by opening or importing this file (UI:R). No privileges are required (PR:N), but user interaction is mandatory. The vulnerability does not affect the integrity or availability of the system but poses a confidentiality risk. The affected product version is listed as '0', which likely indicates early or initial versions of Canva Affinity. There are no known exploits in the wild, and no patches have been released at the time of publication. The vulnerability was reserved in December 2025 and published in March 2026. Given the nature of EMF files, which are commonly used for vector graphics and images, this vulnerability could be exploited in environments where users import or open external EMF files, such as graphic design or publishing workflows.

The primary impact of CVE-2025-64776 is the potential disclosure of sensitive information due to out-of-bounds memory reads. This can lead to leakage of confidential data such as cryptographic keys, user credentials, or proprietary information stored in memory. Although the vulnerability does not allow code execution or system compromise, the confidentiality breach can have serious consequences, especially for organizations handling sensitive or regulated data. The requirement for local access and user interaction limits the attack scope, but targeted spear-phishing or social engineering attacks could trick users into opening malicious EMF files. The availability and integrity of systems remain unaffected, reducing the risk of denial-of-service or data manipulation attacks. However, the exposure of sensitive information can facilitate further attacks or compliance violations. Organizations using Canva Affinity in creative, marketing, or publishing sectors worldwide could be impacted, particularly if they process untrusted EMF files.

To mitigate CVE-2025-64776, organizations should implement the following specific measures: 1) Restrict or disable the processing of EMF files within Canva Affinity if possible, especially from untrusted or external sources. 2) Educate users to avoid opening or importing EMF files from unknown or suspicious origins. 3) Employ application whitelisting and sandboxing techniques to isolate Canva Affinity processes and limit memory exposure. 4) Monitor and filter inbound files at email gateways and endpoint security solutions to detect and block malicious EMF files. 5) Maintain strict access controls and least privilege principles to reduce the risk of local exploitation. 6) Stay alert for official patches or updates from Canva and apply them promptly once available. 7) Conduct regular memory and process monitoring to detect anomalous behavior related to file processing. These targeted actions go beyond generic advice by focusing on controlling EMF file handling and user behavior specific to this vulnerability.
