GHSA-52CP-R559-CP3M js-yaml: YAML merge-key chains can force quadratic CPU consumption
Impact js-yaml can spend quadratic CPU time parsing a document whose size grows only linearly. The issue is triggered by a chain of mappings where each mapping merges the previous one: yaml a0: &a0 k0: 0 a1: &a1 1s doc size 100K js import performance from 'node:perfhooks' import Buffer from...

GHSA-724G-MXRG-4QVM js-yaml: Quadratic-complexity (O(n^2)) DoS via !!omap tag in YAML11_SCHEMA
Summary js-yaml v5.x introduces YAML11SCHEMA support with the !!omap ordered map tag. The omapTag.addItem function performs a linear On scan for duplicate key detection on every insertion, resulting in On^2 total time to parse a document with n omap entries. An attacker can send a small crafted...

SUSE CVE-2026-59885
pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER, CER, and DER decoders process OBJECT IDENTIFIER and RELATIVE-OID values in quadratic time relative to the number of arcs, so a small crafted payload containing an OID with many arcs consumes excessive CPU per decode call and c...
CVE-2026-48801
A flaw was found in linkify-it, a library for recognizing links with full Unicode support. The LinkifyIt.prototype.match function, the package's primary public API, has an algorithmic complexity of ON² for inputs containing many fuzzy links or emails. This can be exploited by a remote attacker...
CVE-2026-48801
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...
