Security readout for executives and security teams
Plain-English summary
Canva’s Android app before version 2.376.0 could load an attacker-controlled webpage inside a trusted app component. If a user opened such a page, it could communicate with Canva using that user’s active session, potentially exposing information or enabling unauthorized actions. The issue requires user interaction but carries a critical CVSS score of 9.6.
Executive priority
Treat this as an urgent mobile application update because authenticated Canva sessions and business content may be exposed. Prioritize users handling sensitive designs, credentials, customer materials, or administrative functions. The required user interaction reduces automatic exploitation risk, but the critical impact and low attack complexity justify rapid remediation.
Technical view
The flaw involves an external origin loaded in a privileged Android WebView, creating an unsafe trust boundary. An attacker controlling the loaded page could communicate with Canva through the victim’s authenticated session. The CVSS vector indicates network reachability, low complexity, no required privileges, required user interaction, changed scope, and high confidentiality and integrity impact.
Likely exposure
Android devices running Canva versions earlier than 2.376.0 are potentially exposed, particularly where users may open attacker-controlled content within the app. The supplied sources do not identify affected operating-system versions, configuration prerequisites, enterprise deployment patterns, or reliable indicators of compromise.
Exploitation context
Successful exploitation requires a user to load a page controlled by the threat actor. No supplied source reports active exploitation, and the CVE is not listed as KEV in the provided bundle. Public exploit availability, attack prevalence, and observed targeting are not established by the evidence provided.
Researcher notes
The record maps the issue to CWE-940 and describes external-origin access through a privileged WebView. The supplied evidence does not disclose the vulnerable component, origin-validation failure, exposed bridge or API, affected Android releases, indicators, exploit availability, or patch internals. Testing should remain controlled and avoid interacting with real user sessions.
Mitigation direction
- Update the Canva Android app to version 2.376.0 or later.
- Prioritize managed devices where Canva is installed and users handle sensitive information.
- Restrict outdated Canva versions through mobile application management where available.
- Check Canva’s security guidance for any additional mitigations or incident-response recommendations.
Validation and detection
- Inventory installed Canva Android versions and identify releases earlier than 2.376.0.
- Confirm managed devices successfully received version 2.376.0 or later.
- Review available mobile and identity telemetry for suspicious Canva session activity.
- Revoke affected sessions if investigation identifies credible signs of unauthorized access.
