figlet is vulnerable to denial of service via unbounded loop when whitespaceBreak is used with a small width
Historical advisory recorded 23 Oct 2026 15:48:27 UTC. Read the latest advisory.
cve-program · CVE-2026-96780
Publishedfiglet.js is a FIG driver written in JavaScript that aims to implement the FIGfont specification. Prior to 1.11.3, text() and textSync() can enter an unbounded loop when whitespaceBreak is enabled and width is smaller than the rendered width of a single FIGlet character. Under these conditions, breakWord() cannot find a valid break point and returns without consuming a character, so generateFigTextLines() repeatedly processes the same input while consuming CPU and growing memory. The non-default option and attacker-controlled width must both reach an affected call. This issue is fixed in version 1.11.3.
