CVE-2026-3031Network attack vector

Unspecified impact from embedded unsupported JPEG library

Published Jul 16, 2026 · Updated Jul 16, 2026

Use of an unmaintained component in Image::EPEG through 0.15 allows attackers to cause unspecified impact via unspecified vectors. The epeg/src/lib/epeg_main.c locus embeds Epeg 0.9.0, an unsupported JPEG thumbnail library last updated in 2004. CPANSec has not identified a specific defect, attacker-controlled input path, or concrete confidentiality, integrity, or availability consequence.
