CVE-2026-48959: CWE-407 Inefficient Algorithmic Complexity in PMQS IO::Uncompress::UnzipCVE-2026-48959 0 CVE-2026-48959 is a vulnerability in IO::Uncompress::Unzip for Perl versions before 2. 220 that allows CPU exhaustion via an inefficient algorithmic complexity issue. The fastForward() function incorrectly compares the digit count of the offset against the chunk size, causing the chunk size to shrink drastically and resulting in a per-byte read loop. This behavior can be triggered when extracting a named entry from a crafted zip file, potentially causing high CPU usage proportional to the compressed size of the entry, up to 4 GiB. No patch or official remediation has been confirmed yet, and no known exploits are reported in the wild.
