Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate CVE-2025-61952, organizations should implement the following specific measures: 1) Restrict the acceptance and opening of EMF files from untrusted or unknown sources within Canva Affinity workflows to reduce exposure to malicious files. 2) Educate users on the risks of opening unsolicited or suspicious EMF files, emphasizing cautious handling of email attachments and downloads. 3) Monitor and filter inbound files at the email gateway and endpoint security solutions to detect and block potentially malicious EMF files. 4) Maintain strict access controls and network segmentation to limit the ability of attackers to deliver malicious files to targeted users. 5) Once the vendor releases a patch or update addressing this vulnerability, prioritize timely deployment across all affected systems. 6) Employ memory protection and application sandboxing technologies where possible to limit the impact of out-of-bounds reads. 7) Conduct regular security awareness training focused on social engineering tactics that could be used to deliver malicious files. 8) Implement endpoint detection and response (EDR) solutions to identify anomalous application behavior related to file processing. These targeted steps go beyond generic advice by focusing on file handling policies, user education, and layered defenses specific to the nature of this vulnerability.

Description

CVE-2025-61952 is an out-of-bounds read vulnerability in the EMF (Enhanced Metafile) processing functionality of Canva Affinity version 3.0.1.3808. Exploitation requires a user to open a specially crafted EMF file, which triggers the vulnerability and may lead to disclosure of sensitive information. The vulnerability does not allow code execution or integrity compromise but can leak confidential data. It has a CVSS score of 6.1, indicating medium severity, with low attack complexity and no privileges required, but user interaction is necessary. There are no known exploits in the wild at this time, and no patches have been released yet. Organizations using Canva Affinity for graphic design should be cautious when handling untrusted EMF files.

Impact

The primary impact of CVE-2025-61952 is the potential unauthorized disclosure of sensitive information from the memory of systems running Canva Affinity 3.0.1.3808. This could include confidential user data, credentials, or proprietary information that resides in memory adjacent to the EMF processing buffers. While the vulnerability does not allow modification of data or denial of service, the confidentiality breach could facilitate further attacks such as phishing, credential theft, or corporate espionage. Organizations relying on Canva Affinity for design work, especially those handling sensitive or proprietary graphics, intellectual property, or client data, face risks of data leakage. The requirement for user interaction means social engineering or targeted delivery of malicious EMF files is necessary, which may limit widespread exploitation but increases risk in targeted attacks. The absence of known exploits reduces immediate threat but also means organizations should proactively prepare. The impact is more pronounced in sectors with high confidentiality requirements such as government, finance, legal, and creative industries.

Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
