CVE-2024-55918Network attack vector

HTML injection via ambiguous scheme resolution

Published Dec 13, 2024 · Updated Dec 17, 2024

HTML injection in Graphics::ColorNames before 3.2.0 allows attackers to affect HTML output through a crafted current-directory file. The scheme-loading path does not unambiguously separate Perl module names from filenames, so a matching local file is consumed as a color scheme. Exploitation requires an attacker-controlled file in the application's working directory; the documented consequence is limited to HTML injection.
