CVE-2025-58427 is a medium-severity vulnerability classified as CWE-125 (Out-of-bounds Read) found in the Enhanced Metafile (EMF) functionality of Canva Affinity version 3.0.1.3808. The vulnerability arises when the application processes specially crafted EMF files, which can cause it to read memory outside the intended buffer boundaries. This out-of-bounds read can lead to the disclosure of sensitive information stored in adjacent memory areas, potentially exposing confidential data to an attacker. Exploitation requires the victim to open a malicious EMF file, implying user interaction is necessary. The attack vector is local (AV:L), meaning the attacker must have some level of access to deliver the file to the victim. No privileges are required (PR:N), and the attack complexity is low (AC:L). The vulnerability does not impact integrity or availability but compromises confidentiality with limited impact on system stability. As of the publication date, no patches or known exploits exist, but the vulnerability is publicly disclosed, increasing the risk of future exploitation. The lack of a patch necessitates proactive mitigation strategies. Canva Affinity is a graphic design tool with a user base that includes professionals and organizations handling graphical content, making this vulnerability relevant to sectors relying on secure design workflows.

The primary impact of CVE-2025-58427 is the potential unauthorized disclosure of sensitive information from the memory of systems running Canva Affinity 3.0.1.3808 when processing malicious EMF files. While it does not allow code execution or system compromise, the confidentiality breach can expose sensitive design data, intellectual property, or other in-memory information. This could lead to information leakage that benefits attackers in targeted espionage or competitive intelligence scenarios. The requirement for user interaction and local access limits the attack scope but does not eliminate risk, especially in environments where users frequently exchange graphic files. Organizations in creative industries, marketing, and media production are particularly vulnerable. The absence of known exploits currently reduces immediate risk but the public disclosure may attract attackers to develop exploits. The vulnerability could also be leveraged as part of a multi-stage attack chain to gather intelligence or facilitate further compromise.

1. Avoid opening EMF files from untrusted or unknown sources until a patch is released. 2. Implement strict file handling policies within organizations using Canva Affinity, including disabling or restricting EMF file support if possible. 3. Employ endpoint security solutions capable of scanning and blocking malicious EMF files. 4. Educate users about the risks of opening unsolicited graphic files and encourage verification of file origins. 5. Monitor Canva’s official channels for security updates and apply patches promptly once available. 6. Use application whitelisting and sandboxing techniques to limit the impact of potential exploitation. 7. Conduct regular security audits of graphic design workflows to identify and mitigate exposure to malicious files. 8. Consider network segmentation to isolate systems used for graphic design from critical infrastructure to reduce lateral movement risk.
