"value": "ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. From 10.1.1 until 10.2.2, every special-use classification method is built on isInSubnet, which short-circuits to false whenever the address\u0027s own subnet mask is shorter than the reference range\u0027s mask. That mask comes verbatim from the CIDR suffix on the parsed input, so appending a suffix such as /0 suppresses classification entirely: isLoopback(), isPrivate(), isLinkLocal(), isCGNAT(), isMulticast(), isUnspecified(), isBroadcast(), isULA(), and getType() all report an internal address as unremarkable, while correctForm() and address still return the real internal target. An application that builds a network trust-boundary decision on these checks, for example a filter intended to block Server-Side Request Forgery, or SSRF, may therefore treat an internal target as external and allow the request. The underlying bit comparison is correct, and mask(n) already returns the first n bits of the full parsed address independently of subnetMask; the defect is solely that the containment guard sits in the classification path. This issue is fixed in version 10.2.2."

GHSA-5P4M-2WFM-XMQJ
Vulnerability from github – Published: 2026-08-06 20:27 – Updated: 2026-08-06 20:27Quadratic CPU consumption in !!omap resolution (js-yaml 3.x and 4.x)
Summary
resolveYamlOmap() enforces key uniqueness for !!omap sequences with a linear
scan (objectKeys.indexOf(...)) inside the per-element loop, making resolution
O(n²) in the number of entries. A modestly sized YAML document therefore
consumes disproportionate CPU inside yaml.load(), giving a denial of service
against any consumer that parses untrusted YAML.
!!omap is registered in the default schema
(lib/schema/default.js → require('../type/omap')), so a plain
yaml.load(untrustedInput) with no options is affected — no custom schema or
non-default configuration is required.
This is the same weakness as CVE-2026-59870 / GHSA-724g-mxrg-4qvm, which was fixed in the 5.x line in 5.2.1. That fix was never backported: both currently maintained legacy lines still carry the original implementation.
Affected versions
| Line | Latest tested | Status |
|---|---|---|
| 3.x | 3.15.0 | Affected — objectKeys.indexOf(pairKey) at lib/type/omap.js:29 |
| 4.x | 4.3.0 | Affected — objectKeys.indexOf(pairKey) at lib/type/omap.js:30 |
| 5.x | 5.2.2 | Not affected — fixed in 5.2.1 (uses a Set) |
Both figures are the newest release of each line at the time of writing, so this is not a "you are on an old version" issue.
Details
lib/type/omap.js (js-yaml 4.3.0):
if (objectKeys.indexOf(pairKey) === -1) objectKeys.push(pairKey)
else return false
objectKeys grows by one element per entry, and Array.prototype.indexOf is a
linear scan, so resolving an n-entry !!omap performs roughly
1 + 2 + … + n comparisons — quadratic in n. The work happens synchronously
inside yaml.load(), blocking the event loop for its whole duration.
The 5.x line already solves exactly this by tracking seen keys in a Set
(src/tag/sequence/omap.ts):
if (carrier.seen.has(key)) return 'duplicate key in ordered map'
carrier.seen.add(key)
Proof of concept
// poc.js — node poc.js
const yaml = require('js-yaml');
const doc = n => '!!omap\n' + Array.from({length: n}, (_, i) => `- k${i}: ${i}`).join('\n') + '\n';
for (const n of [10000, 20000, 40000, 80000]) {
const d = doc(n), t = Date.now();
yaml.load(d); // default schema, no options
console.log(`n=${n} bytes=${d.length} load=${Date.now() - t}ms`);
}
Measured (node v20.20.2, default heap, no flags)
js-yaml 4.3.0
n=10000 bytes=137787 load=54ms
n=20000 bytes=297787 load=169ms
n=40000 bytes=617787 load=646ms
n=80000 bytes=1257787 load=2607ms
js-yaml 3.15.0
n=10000 bytes=137787 load=53ms
n=20000 bytes=297787 load=166ms
n=40000 bytes=617787 load=641ms
n=80000 bytes=1257787 load=2567ms
Runtime grows by a factor of ~4 for each doubling of n, which is the
signature of O(n²) (linear growth would be ~2×).
Scaling further: a 2.48 MB document with 150,000 entries blocked
yaml.load() for 10.8 seconds.
Impact
Any service that parses attacker-influenced YAML with js-yaml 3.x or 4.x can be stalled with a small input. Because the loop is synchronous, a single request blocks the Node.js event loop and stalls every other request in the process — so the amplification is per-process, not just per-request.
Suggested severity: consistent with CVE-2026-59870 (the same weakness in 5.x), i.e. Availability-only impact, network attack vector, no privileges or user interaction required.
Suggested fix
Mirror the 5.x fix — replace the linear scan with a Set:
// lib/type/omap.js
const seen = new Set()
// ...
if (seen.has(pairKey)) return false
seen.add(pairKey)
This preserves the existing duplicate-key rejection semantics exactly while
making resolution O(n). A maxOmapLength-style cap would also work, but the
Set matches what 5.x already ships and requires no new option.

Vulnerability from github – Published: 2026-07-21 22:07 – Updated: 2026-07-21 22:07Impact
A number of vulnerabilities, two rated as "High" severity using CVSSv4, have been discovered and fixed in the upstream libvips dependency.
Those processing untrusted input with versions of sharp prior to 0.35.0 are affected.
Patches
Using prebuilt binaries provided by sharp?
Most people rely on the prebuilt binaries provided by sharp.
Please upgrade sharp to the latest version, currently 0.35.3, which provides libvips 8.18.3.
Using a globally-installed libvips?
Please ensure you are using the latest libvips 8.18.3.
Workarounds
Add the following to your code to prevent sharp from decoding GIF, TIFF and VIPS images.
sharp.block({ operation: ["VipsForeignLoadNsgif", "VipsForeignLoadTiff", "VipsForeignLoadVips"] });
