CVE-2025-62500 is a medium-severity vulnerability classified under CWE-125 (Out-of-bounds Read) affecting Canva Affinity version 3.0.1.3808. The flaw exists in the Enhanced Metafile (EMF) processing component, where the application fails to properly validate input boundaries when parsing EMF files. An attacker can exploit this by delivering a specially crafted EMF file that triggers the application to read memory beyond the allocated buffer. This out-of-bounds read can expose sensitive information residing in adjacent memory areas, potentially leaking confidential data such as user credentials, cryptographic keys, or other private information stored in the process memory. The vulnerability requires the victim to open the malicious EMF file, implying user interaction is necessary. No privileges or authentication are required to exploit this vulnerability, but local or remote delivery of the malicious file is needed. The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:L) reflects that the attack vector is local, with low attack complexity, no privileges required, user interaction required, unchanged scope, high confidentiality impact, no integrity impact, and low availability impact. There are no known exploits in the wild at the time of publication, and no patches have been released yet. This vulnerability highlights the risks associated with parsing complex file formats like EMF without robust boundary checks.

The primary impact of CVE-2025-62500 is the potential disclosure of sensitive information from the memory of the Canva Affinity application process. This can compromise confidentiality, especially if the leaked memory contains sensitive user data, authentication tokens, or cryptographic material. Although the vulnerability does not affect integrity or availability, the exposure of confidential data can lead to further attacks such as credential theft, unauthorized access, or data leakage. Organizations relying on Canva Affinity for design workflows may face risks if attackers can trick users into opening malicious EMF files, especially in environments where sensitive design assets or proprietary information are handled. The requirement for user interaction and local access reduces the likelihood of widespread automated exploitation but does not eliminate targeted attacks. The absence of known exploits in the wild currently limits immediate risk, but the medium severity score indicates that timely mitigation is important to prevent future exploitation.

1. Until an official patch is released, implement strict controls on the sources of EMF files opened with Canva Affinity, including blocking or quarantining EMF files from untrusted or unknown origins. 2. Educate users to avoid opening EMF files received from unsolicited emails or unverified sources to reduce the risk of social engineering attacks. 3. Employ endpoint security solutions capable of detecting and blocking suspicious file formats or anomalous application behavior related to EMF file processing. 4. Monitor Canva’s official channels for security updates and apply patches promptly once available. 5. Consider disabling or restricting EMF file support in Canva Affinity if the functionality is not essential to your workflows. 6. Use application whitelisting and privilege restrictions to limit the ability of attackers to deliver or execute malicious files. 7. Conduct regular security awareness training emphasizing the risks of opening unexpected file attachments. 8. Implement network-level protections such as email filtering and sandboxing to detect and block malicious EMF files before they reach end users.
