CVSS 3.1
8.6 highCVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:HCVE-2020-17354
High (8.6) in lilypond lilypond. EPSS 0.4% chance of exploitation in the next 30 days.
LilyPond before 2.24 allows attackers to bypass the -dsafe protection mechanism via output-def-lookup or output-def-scope, as demonstrated by dangerous Scheme code in a .ly file that causes arbitrary code execution during conversion to a different file format. NOTE: in 2.24 and later versions, safe mode is removed, and the product no longer tries to block code execution when external files are used.
