CVE-2026-101130

Status: Awaiting AnalysisLow (3.6)—

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.

CVSS

Version: 3.1
Vector: CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:L
Base score: 3.6

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.12%
Percentile among all scored CVEs: 2
Score date: 10/16/2026

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).
