CVE-2026-7040
Text::Minify::XS versions from 0.3.0 before 0.7.8 for Perl have a heap overflow when processing some malformed UTF-8 characters.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.44%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Text::Minify::XS versions from 0.3.0 before 0.7.8 for Perl have a heap overflow when processing some malformed UTF-8 characters. The minify functions mishandled some malformed UTF-8 characters, leading to heap corruption. Note that the minify_utf8 function is an alias for minify.
