CVE-2020-24430

Status: ModifiedHigh (7.8)—

Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) are affected by a use-after-free vulnerability when handling malicious JavaScript. This vulnerability could result in arbitrary code execution in the context of the current user. Exploitation 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).
