CVE-2026-48959

IO::Uncompress::Unzip versions before 2.220 for Perl allow CPU exhaustion via per-byte read loop in fastForward. fastForward compares length $offset the digit count of the offset, 1 to 19 against the chunk size $c instead of $offset itself, so $c shrinks from 16 KiB to 1-19 bytes per iteration...

CVE-2026-48959

The IO::Uncompress::Unzip Perl module (versions before 2.220 ) is vulnerable to a CPU exhaustion attack. The root cause is located in the fastForward() function, which incorrectly compares the length of the $offset variable (a digit count between 1 and 19) against the chunk size $c, rather than c...
