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

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

Description

CVE-2025-47873 is an out-of-bounds read vulnerability in the EMF processing functionality of Canva Affinity version 3.0.1.3808. An attacker can exploit this by crafting a malicious EMF file that triggers the vulnerability, potentially leading to unauthorized disclosure of sensitive information. The vulnerability requires local access and user interaction to open the malicious file but does not require privileges or authentication. The CVSS score is 6.1 (medium severity), reflecting high confidentiality impact but limited integrity and availability impact. No known exploits are currently reported in the wild. Organizations using Canva Affinity for graphic design should be aware of this vulnerability and apply patches once available or implement mitigations to reduce risk.

Impact

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.
