Linkify-it (linkify-it) prior to version 5.0.1 has an O(N^2) scan loop in LinkifyIt.prototype.match, making inputs with many fuzzy links or emails vulnerable to resource exhaustion on a request hot path that renders untrusted Markdown with linkify: true. The issue arises from re-slicing input and...

CVE-2026-59886

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the univ.Real type converted its mantissa, base, and exponent value to a Python float using exact big-integer exponentiation. A BER, CER, or DER encoded REAL value only a few bytes long can carry a very large exponent, causing float...

CVE-2026-59884

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets without an upper bound on the tag ID size, allowing a crafted input to force construction of an arbitrarily large integer with C...
