• CVE-2026-28450: 0.40% estimated exploitation activity in the next 30 days; percentile 33.73 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary The OpenClaw Nostr channel plugin (optional, disabled by default, installed separately) exposes profile management HTTP endpoints under /api/channels/nostr/:accountId/profile (GET/PUT) and /api/channels/nostr/:accountId/profile/import (POST). In affected versions, these routes were dispatched via the gateway plugin HTTP layer without requiring gateway authentication, allowing unauthenticated remote callers to read or mutate the Nostr profile and persist changes to the gateway config. Profile updates are also published as a signed Nostr kind:0 event using the bot's private key. Deployments that do not have the Nostr plugin installed and enabled are not impacted. Affected Packages / Versions - Package: openclaw (npm) - Affected versions: <= 2026.2.9 - Fixed versions: = 2026.2.12 - Scope note: only affects deployments with the optional @openclaw/nostr plugin installed and enabled Details This is exploitable when the gateway HTTP port is reachable beyond localhost (for example:…

# Patch Next advisory brief: CVE-2026-28450

Advisory: OpenClaw's unauthenticated Nostr profile HTTP endpoints allow remote profile/config tampering
IDs: CVE-2026-28450, GHSA-mv9j-6xhh-g383
Record: https://patchnext.com/advisories/cve-2026-28450 (revision 3, source checked 26 Oct 2026, 12:43 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: openclaw 2026.2.12. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm openclaw: affected < 2026.2.12; fixed in 2026.2.12

## Suggested inspection (read-only)
- `npm ls openclaw --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 openclaw.
- 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.
