CVE-2021-28573

Status: ModifiedMedium (6.5)—

Adobe Animate version 21.0.5 (and earlier) is affected by an Out-of-bounds Read vulnerability when parsing a specially crafted file. An unauthenticated attacker could leverage this vulnerability to disclose sensitive information in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

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).
