CVE-2026-27238
HighCVSS 7.8Exploitation Probability (EPSS)
Low risk8th percentile - higher than 8% of all known CVEs
Summary
InDesign Desktop versions 20.5.2, 21.2 and earlier are affected by a Heap-based Buffer Overflow vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
Risk Assessment
An attacker can execute arbitrary code on the victim's machine if the victim opens a malicious file, potentially leading to system takeover. However, this requires user action.
Recommendation
Update InDesign Desktop to a version later than 20.5.2 or 21.2 if available, and exercise caution when opening files from untrusted sources. Also implement email and file browsing security policies.
