What is CVE-2026-44482?

CVE-2026-44482 is an improper input validation flaw in soundcloud-rpc. The product fails to verify the format, range, or origin of attacker-controlled input, and downstream code paths then act on values they should have rejected. Vendor description: soundcloud-rpc is a SoundCloud Client with Discord Rich Presence, Dark Mode, Last.fm and AdBlock support. Prior to 0.1.8, a track title containing an HTML payload executed locally in the Electron app.

Why this CVE matters

Input validation gaps in a management or API endpoint are usually a sign that other defensive layers were trusted to catch malformed input. When they do not, the impact ranges from data corruption to full code execution depending on what the unvalidated input controls.

For deployments of soundcloud-rpc that have been exposed to the public internet during the disclosure window, the operating assumption should be that scanning has already happened. Even where exploitation has not been publicly observed, scanning for the vulnerable fingerprint is cheap and routine. Patching closes the door; log review and credential rotation close out the rest of the response.

Am I affected?

You are affected if your installation matches any of these version ranges:

Check your installed version against the list above. If you cannot determine the version, treat the system as affected and follow the upgrade path below.

Open soundcloud-rpc's About dialog or run the vendor-documented version-check command. Compare the result against the affected ranges in the advisory.

How to fix CVE-2026-44482

  1. Read the vendor advisory in full: https://github.com/richardhbtz/soundcloud-rpc/security/advisories/GHSA-p37x-32p8-445f
  2. Upgrade soundcloud-rpc to the patched build listed in the vendor advisory.
  3. Back up the configuration (and database, where applicable) before upgrading.
  4. Apply the patch in a maintenance window. For HA pairs, upgrade the standby node first, fail over, then upgrade the former primary.
  5. Restart the affected service so the patched binary loads, then verify the new version (see verification section).

Update the npm package


# CVE-2026-44482 affects soundcloud-rpc < 0.1.8. Fixed in 0.1.8.
# Vendor advisory: https://github.com/richardhbtz/soundcloud-rpc/security/advisories/GHSA-p37x-32p8-445f

# 1. Show the currently resolved version inside the project.
npm ls soundcloud-rpc

# 2. Update to the patched release named in the advisory.
npm install soundcloud-rpc@0.1.8
npm audit fix

# 3. Lock-file enforcement for CI / production.
npm ci

# 4. Verify.
npm ls soundcloud-rpc
# The resolved version must match 0.1.8 (or a later patched release).


# Same flow from a Windows admin workstation.
npm install soundcloud-rpc@0.1.8
npm ls soundcloud-rpc

Verify the fix landed


# CVE-2026-44482 verification checklist.

# 1. Confirm the running version matches 0.1.8 (replace the version probe with
#    the platform-specific command shown above).

# 2. Re-scan the host with your vulnerability scanner (Nessus, Qualys, Tenable,
#    OpenVAS, Wazuh). The scanner must no longer flag CVE-2026-44482.

# 3. Inspect recent service and kernel logs for crash-loops or rollback events.
journalctl -u <service-name> --since "10 minutes ago"
dmesg --since "10 minutes ago"

# 4. Cross-check the running build against the vendor advisory:
#    https://github.com/richardhbtz/soundcloud-rpc/security/advisories/GHSA-p37x-32p8-445f

If you cannot patch immediately

No official workaround exists beyond restricting network exposure to the affected component. Apply the vendor patch as the primary remediation.

How to verify the fix worked

If your installation was internet-reachable during the disclosure window, treat log review as part of the remediation rather than an optional follow-up. Look for log entries that do not match your normal request patterns, especially repeated requests to the same uncommon endpoint, and any administrative changes you cannot tie back to a known operator.

Frequently asked questions

Is CVE-2026-44482 being exploited in the wild?

Public exploitation has not been confirmed by CISA at the time of writing. Treat the patch as time-sensitive anyway; reports often lag actual abuse.

Will a WAF or IDS rule fully mitigate CVE-2026-44482?

No. Network-layer filters can reduce noise and slow opportunistic scanners, but they will not stop a determined attacker. The vendor patch is the only durable fix.

How long should I plan for the upgrade?

Typical vendor-documented upgrade windows for soundcloud-rpc run from a few minutes to under an hour depending on cluster size. Test in a staging environment first and follow the vendor's documented HA upgrade order.
