CVE-2026-110676

Cpanel::JSON::XS versions before 4.80 for Perl allow memory exhaustion by encoding exponent notation as full decimal digits under allowbignum. With allowbignum, a JSON number with a fraction or exponent decodes to a Math::BigFloat, which stores the exponent separately and so decodes cheaply...

CVE-2026-110676

The Cpanel::JSON::XS module for Perl (versions before 4.80 ) is vulnerable to memory exhaustion and CPU exhaustion when processing untrusted JSON data with the allow_bignum option enabled. The root cause is that while decoding numbers with exponents is efficient (using Math::BigFloat ), encoding ...
