What is CVE-2026-22644?

CVE-2026-22644 is a security flaw in Incoming Goods Suite. Certain requests pass the authentication token in the URL as string query parameter, making it vulnerable to theft through server logs, proxy logs and Referer headers, which could allow an attacker to hijack the user's session and gain unauthorized access.

Why this CVE matters

Unpatched network-facing software is the leading initial-access vector in public breach reporting. Treat any CVSS-9 class flaw on an internet-reachable system as urgent, regardless of whether public exploit code has been observed yet.

For deployments of Incoming Goods Suite 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 Incoming Goods Suite'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-2026-22644

  1. Read the vendor advisory in full: https://sick.com/psirt
  2. Upgrade Incoming Goods Suite 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).

Verify the fix landed


# 1. Confirm the running version matches the patched build
#    (target per advisory: see vendor advisory)
#    Use the platform-specific version probe shown above.

# 2. Re-scan the host with your vulnerability scanner (Nessus, Qualys, Tenable,
#    Rapid7, OpenVAS). The scanner should no longer flag CVE-2026-22644.

# 3. Inspect service and kernel logs for crash-loops or rollback events
journalctl --since "10 minutes ago" | grep -iE 'error|fail|panic'
dmesg --since "10 minutes ago" | tail -50

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-2026-22644 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-2026-22644?

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 Incoming Goods Suite 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.
