CVE-2026-96393

Status: Awaiting AnalysisLow (3.6)—

The Affinity by Canva app before 3.3.1 (October 2026 release) did not perform adequate bounds checking when parsing Affinity document files, leading to an out-of-bounds pointer dereference. A threat actor could craft an Affinity document that, when opened by a user in Affinity, could result in an application crash.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
