Status: ModifiedCritical (10)—

The initialize method in the Histogram class in lib/colorscore/histogram.rb in the colorscore gem before 0.0.5 for Ruby allows context-dependent attackers to execute arbitrary code via shell metacharacters in the (1) image_path, (2) colors, or (3) depth variable.

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).
