CVE-2025-47873 is a medium-severity vulnerability categorized as 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 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 the ability to deliver or convince the user to open the malicious file, but no privileges or authentication are required. The vulnerability does not affect integrity or availability but has a high impact on confidentiality. No patches are currently linked, and no known exploits have been reported in the wild as of the publication date. The vulnerability was reserved in December 2025 and published in March 2026, indicating recent discovery and disclosure. The affected product, Canva Affinity, is a graphic design tool used globally, and the EMF format is a common vector for vector graphics, increasing the risk if malicious files are shared or downloaded.

The primary impact of CVE-2025-47873 is the potential unauthorized disclosure of sensitive information due to out-of-bounds memory reads. For organizations, this could lead to leakage of confidential data, intellectual property, or user information embedded in memory during EMF file processing. Although the vulnerability does not allow code execution or system compromise, the confidentiality breach could facilitate further attacks or data exposure incidents. The requirement for user interaction limits large-scale automated exploitation but does not eliminate risk, especially in environments where users frequently exchange graphic files. Industries relying heavily on graphic design, marketing, and digital content creation are particularly at risk. Additionally, the lack of available patches at the time of disclosure increases exposure. The vulnerability could be leveraged in targeted phishing campaigns or supply chain attacks involving malicious EMF files. Overall, the impact is moderate but significant enough to warrant prompt attention.

1. Monitor for official patches or updates from Canva and apply them immediately once available to remediate the vulnerability. 2. Until patches are released, implement strict file handling policies that restrict or scan EMF files before opening, using advanced endpoint protection or sandboxing solutions. 3. Educate users about the risks of opening unsolicited or suspicious graphic files, especially EMF files from untrusted sources. 4. Employ network-level controls to block or quarantine EMF files received via email or file-sharing platforms. 5. Use application whitelisting to limit execution of untrusted software and reduce the risk of malicious file processing. 6. Conduct regular security awareness training focusing on social engineering tactics that could deliver malicious files. 7. Consider disabling EMF file support in Canva Affinity if feasible or using alternative file formats until a fix is available. 8. Monitor logs and endpoint behavior for unusual activity related to file processing to detect potential exploitation attempts early.
