CVE-2025-61979 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 EMF (Enhanced Metafile) functionality, where improper bounds checking allows an attacker to read memory outside the intended buffer boundaries. By delivering a specially crafted EMF file and convincing a user to open it, an attacker can trigger this out-of-bounds read, potentially disclosing sensitive information residing in adjacent memory areas. The vulnerability does not allow code execution or integrity modification but compromises confidentiality by leaking data. The attack vector is local with low complexity, requiring user interaction but no privileges or authentication. The CVSS 3.1 score of 6.1 reflects a medium impact primarily on confidentiality with limited availability impact and no integrity impact. No public exploits or patches are currently available, indicating a window of exposure. The vulnerability highlights risks in handling complex graphic file formats and the importance of robust input validation in multimedia applications. Organizations relying on Canva Affinity for design workflows should monitor for updates and consider restricting EMF file usage until remediation is available.

The primary impact of CVE-2025-61979 is the potential disclosure of sensitive information due to out-of-bounds memory reads when processing malicious EMF files. This can lead to leakage of confidential data such as user credentials, cryptographic keys, or other sensitive application memory contents. Although it does not allow code execution or system compromise, the confidentiality breach can facilitate further attacks or data exposure. The requirement for user interaction and local access limits remote exploitation but does not eliminate risk, especially in environments where untrusted files are shared or downloaded. For organizations, this vulnerability could undermine trust in design assets and expose proprietary or personal information. The absence of patches increases exposure duration, and the medium severity rating suggests a moderate but non-critical threat. Industries with high reliance on graphic design software, including media, marketing, and creative sectors, face operational risks if exploited. Additionally, regulatory compliance regarding data protection could be impacted if sensitive information is leaked.

To mitigate CVE-2025-61979, organizations should implement the following specific measures: 1) Restrict or disable the import and opening of EMF files from untrusted or unknown sources within Canva Affinity until a patch is released. 2) Employ application whitelisting and sandboxing to isolate Canva Affinity processes and limit the impact of potential memory disclosures. 3) Monitor and control file sharing channels to prevent distribution of malicious EMF files internally. 4) Use endpoint protection solutions capable of detecting anomalous file parsing or memory access patterns related to EMF processing. 5) Educate users about the risks of opening unsolicited or suspicious graphic files and enforce strict user interaction policies. 6) Regularly check for vendor updates and apply patches promptly once available. 7) Consider network segmentation to limit exposure of systems running Canva Affinity. 8) Utilize memory protection technologies such as ASLR and DEP to reduce the risk of exploitation. These targeted actions go beyond generic advice by focusing on file type restrictions, user behavior, and process isolation specific to this vulnerability.
