How to Fix CVE-2026-0748: Access Control Bypass in Internationalization (i18n) - i18n_node submodule

Q: Is CVE-2026-0748 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.

Q: Will a WAF or IDS rule fully mitigate CVE-2026-0748?

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.

Q: How long should I plan for the upgrade?

Typical vendor-documented upgrade windows for Internationalization (i18n) - i18n_node submodule 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.

What is CVE-2026-0748?

CVE-2026-0748 is an access control bypass flaw in Internationalization (i18n) - i18n_node submodule. Authenticated or in some cases unauthenticated requests reach endpoints they should not be allowed to call, exposing administrative functionality or sensitive data. Vendor description: In the Drupal 7 Internationalization (i18n) module, the i18n_node submodule allows a user with both "Translate content" and "Administer content translations" permissions to view and attach unpublished nodes via the translation UI and its autocomplete widget. This bypasses intended access controls and discloses unpublished node titles and IDs.

Why this CVE matters

Access control flaws let an attacker reach endpoints the developers assumed would be reserved for administrators. The impact depends on what those endpoints expose, but for management products the answer is usually configuration changes, log access, or credential reads.

For deployments of Internationalization (i18n) - i18n_node submodule 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:

Internationalization (i18n) - i18n_node submodule: 7.x-1.0 <= 7.x-1.35

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 Internationalization (i18n) - i18n_node submodule'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-2026-0748

The fix is to apply the patched build listed in the Drupal advisory.

Affected versions confirmed in the CVE record:

Internationalization (i18n) - i18n_node submodule ≤ 7.x-1.35

Update the npm package


# Vendor advisory: https://www.herodevs.com/vulnerability-directory/cve-2026-0748
<!-- enrich_agent_2:v1 -->
# Patch in-place.
npm install internationalization (i18n) - i18n_node submodule@<patched-version>
npm audit fix

# Confirm.
npm list internationalization (i18n) - i18n_node submodule

Verify the fix worked


<!-- enrich_agent_2:v1 -->
# 1. Confirm the running version matches the fixed-in version from the advisory.
#    Cross-check against the vendor advisory: https://www.herodevs.com/vulnerability-directory/cve-2026-0748

# 2. Re-scan with your vulnerability scanner. The scanner should no longer flag
#    this CVE on the patched host.
# Example with Nmap NSE:
nmap -sV --script vuln <target-host>

# 3. Inspect the service / kernel logs for crash-loops or rollback events in
#    the first hour after the upgrade.
journalctl -u <service-name> --since "1 hour ago"
dmesg --since "1 hour ago"

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

After applying the patch, verify the running version in the product's admin UI or via the vendor-documented CLI command.
Confirm the patched build matches the version listed in the vendor advisory.
Run an authenticated vulnerability scan with a current signature set and confirm the scanner no longer flags CVE-2026-0748.
Review logs for the entire pre-patch window for indicators of compromise listed in the vendor or CISA advisory.
Confirm any network-layer mitigations that were applied as a stopgap have been reverted (or left in place intentionally) once the patch is verified.

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.
