The Affinity by Canva application before 3.3.1 (October 2026 release) did not perform adequate bounds checking when parsing arrays of string
Noroxi assessment
Priority: Monitor (action score 14/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.12% (FIRST EPSS).
- Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. Special conditions such as timing or configuration are required.
- Fixed version: canva affinity 3.3.1.
Low priority for now. Upgrade to canva affinity 3.3.1 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
The Affinity by Canva application before 3.3.1 (October 2026 release) did not perform adequate bounds checking when parsing arrays of strings in Affinity document files, leading to a heap buffer over-read. A threat actor could craft an Affinity document that, when opened by a user in Affinity, could disclose the contents of adjacent heap memory in the document's text or result in an application crash.
