CVE-2026-8796 Sereal::Decoder versions before 5.005 for Perl allow heap out-of-bounds read via crafted input

Sereal::Decoder versions before 5.005 for Perl allow heap out-of-bounds read via crafted input. In Perl/Decoder/srldecoder.c, srlreadobject and srlreadhash process a COPY tag, a back-reference whose target byte the decoder re-decodes as a fresh tag. When that target byte matches the SHORTBINARY...
