As published by the source; long descriptions are shortened.

Affected Packages / Versions This issue affects the optional voice-call plugin only. It is not enabled by default; it only applies to installations where the plugin is installed and enabled. - Package: @openclaw/voice-call - Vulnerable versions: < 2026.2.3 - Patched versions: = 2026.2.3 Legacy package name (if you are still using it): - Package: @clawdbot/voice-call - Vulnerable versions: <= 2026.1.24 - Patched versions: none published under this package name; migrate to @openclaw/voice-call Summary In certain reverse-proxy / forwarding setups, webhook verification can be bypassed if untrusted forwarded headers are accepted. Impact An external party may be able to send voice-call webhook requests that are accepted as valid, which can result in spoofed webhook events being processed.

# Patch Next advisory brief: CVE-2026-28465

Advisory: OpenClaw optional voice-call plugin: webhook verification may be bypassed behind certain proxy configurations
IDs: CVE-2026-28465, GHSA-3m3q-x3gj-f79x
Record: https://patchnext.com/advisories/cve-2026-28465 (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: High (CVSS 8.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: @openclaw/voice-call 2026.2.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @clawdbot/voice-call: affected <= 2026.1.24
- npm @openclaw/voice-call: affected < 2026.2.3; fixed in 2026.2.3

## Suggested inspection (read-only)
- `npm ls @clawdbot/voice-call --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.
- `npm ls @openclaw/voice-call --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on @clawdbot/voice-call, @openclaw/voice-call.
- 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.
