nuxt-og-image SSRF — bypass of GHSA-pqhr-mp3f-hrpp / v6.2.5 fix (IPv6 + redirect)

CVE-2026-44589GHSA-c2rm-g55x-8hr5

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (nuxt-og-image 6.4.9), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Summary The isBlockedUrl() denylist introduced in nuxt-og-image@6.2.5 to remediate GHSA-pqhr-mp3f-hrpp (Dmitry Prokhorov / Positive Technologies, March 2026) is incomplete. The patch advisory states "Decimal/hexadecimal IP encoding bypasses are also handled" — that part is true (Node's WHATWG URL parser canonicalizes those forms before validation), but the v6.2.5 implementation misses two independent surfaces in the latest release 6.4.8: 1. IPv6 prefix list is incomplete. The IPv6 branch checks only bare === "::1" || startsWith("fc") || startsWith("fd") || startsWith("fe80"). It misses: - [::ffff:7f00:1] — IPv6-mapped IPv4 loopback in pure-hex form (REMAPPEDV4 regex requires dotted-quad). Reaches 127.0.0.1 on a single-stack-IPv4 host with no other primitive needed. - [fec0::/10] (RFC 3879 site-local — deprecated but still routable on legacy networks) - [5f00::/16] (RFC 9602 SRv6 SIDs) - [3fff::/20] (RFC 9637 IPv6 documentation v2) - [64:ff9b:1::/48] (RFC 8215 NAT64 local-use,…

# Patch Next advisory brief: CVE-2026-44589

Advisory: nuxt-og-image SSRF — bypass of GHSA-pqhr-mp3f-hrpp / v6.2.5 fix (IPv6 + redirect)
IDs: CVE-2026-44589, GHSA-c2rm-g55x-8hr5
Record: https://patchnext.com/advisories/cve-2026-44589 (revision 2, source checked 26 Oct 2026, 12:52 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 3.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: nuxt-og-image 6.4.9. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm nuxt-og-image: affected >= 6.2.5, < 6.4.9; fixed in 6.4.9

## Suggested inspection (read-only)
- `npm ls nuxt-og-image --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on nuxt-og-image.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-c2rm-g55x-8hr5 (OSV record GHSA-c2rm-g55x-8hr5 lists affected ranges: npm nuxt-og-image >=6.2.5 <6.4.9 (fixed))
- Verified: https://github.com/advisories/GHSA-c2rm-g55x-8hr5 (GitHub-reviewed advisory GHSA-c2rm-g55x-8hr5 lists affected ranges: npm nuxt-og-image >=6.2.5 <6.4.9)
