CVE-2026-116285

HTTP::Body versions before 1.23_01 for Perl allow CPU exhaustion via quadratic regex backtracking when parsing chunked request bodies.

In chunked mode, used when no content length is given, add() matches each chunk-size line with /^([\da-fA-F]+).*\x0D\x0A/. On a line of hex digits whose first LF has no CR before it, the digits and .* backtrack against each other, so a single add() takes time quadratic in the line's length. Nothing limits how long the line can be.

A remote attacker can exhaust CPU in applications that pass chunked request bodies to HTTP::Body.
