CVE-2025-47873 is a medium severity vulnerability classified under CWE-125 (Out-of-bounds Read) affecting the EMF (Enhanced Metafile) functionality in Canva Affinity version 3.0.1.3808. The vulnerability arises when the software processes specially crafted EMF files that 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 that a user open or import a malicious EMF file, which means user interaction is necessary. The attack vector is local (AV:L), with low attack complexity (AC:L), no privileges required (PR:N), and user interaction required (UI:R). The scope is unchanged (S:U), and the impact is high on confidentiality (C:H), none on integrity (I:N), and low on availability (A:L). Although no code execution or privilege escalation is possible, the confidentiality breach risk is significant in environments where sensitive data is processed or stored in memory near the EMF processing routines. No known exploits have been reported in the wild, and no patches or updates have been released at the time of this analysis. The vulnerability was reserved in December 2025 and published in March 2026 by the CVE database, with Talos as the assigner. Organizations using Canva Affinity, especially in graphic design and content creation, should be aware of this vulnerability and take steps to mitigate risk.

The primary impact of CVE-2025-47873 is the potential disclosure of sensitive information due to an out-of-bounds read in Canva Affinity's EMF processing. This can lead to confidentiality breaches, especially if sensitive data resides in memory adjacent to the vulnerable buffer. While the vulnerability does not allow code execution or system compromise, the exposure of confidential data can have serious consequences, including intellectual property theft, leakage of user data, or exposure of proprietary design elements. The requirement for user interaction and local access limits the attack surface but does not eliminate risk, particularly in environments where users may receive EMF files from untrusted or malicious sources. The medium severity rating reflects these factors. Organizations relying heavily on Canva Affinity for design workflows may face operational risks if sensitive project data is exposed. Additionally, the lack of a patch increases the window of vulnerability until a fix is released. The impact on availability and integrity is minimal, but confidentiality concerns warrant prompt attention.

To mitigate CVE-2025-47873, organizations should implement several specific measures beyond generic advice: 1) Restrict the use and opening of EMF files within Canva Affinity, especially from untrusted or unknown sources, to reduce exposure to malicious files. 2) Employ file validation and scanning tools that can detect malformed or suspicious EMF files before they are opened. 3) Educate users on the risks of opening unsolicited or unexpected EMF files and encourage verification of file sources. 4) Use application whitelisting or sandboxing techniques to isolate Canva Affinity processes, limiting the impact of potential data exposure. 5) Monitor system and application logs for unusual activity related to EMF file handling. 6) Stay informed about vendor updates and apply patches promptly once available. 7) Consider disabling EMF support in Canva Affinity if feasible, or use alternative file formats less prone to such vulnerabilities. These targeted actions can significantly reduce the risk of exploitation while maintaining operational continuity.
