What is CVE-2026-1582?

CVE-2026-1582 is an information disclosure flaw in WP All Export – Drag & Drop Export to Any Custom CSV, XML & Excel. The product returns sensitive data to a caller who should not have access, including credentials, session tokens, or configuration. Disclosure often feeds a follow-up attack chain. Vendor description: The WP All Export plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.4.14 via the export download endpoint. This is due to a PHP type juggling vulnerability in the security token comparison which uses loose comparison (==) instead of strict comparison (===).

Why this CVE matters

Information disclosure flaws are dangerous because they make the next attack easier. Sensitive configuration, session material, or credentials leaked from one endpoint frequently power the follow-on attack that actually takes over the system.

For deployments of WP All Export – Drag & Drop Export to Any Custom CSV, XML & Excel 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 WP All Export – Drag & Drop Export to Any Custom CSV, XML & Excel'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-2026-1582

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

Affected versions confirmed in the CVE record:

Update the affected WordPress plugin / theme


<!-- enrich_agent_2:v1 -->
# Pin to the patched build listed in the [advisory](https://www.wordfence.com/threat-intel/vulnerabilities/id/9a92c682-b8b3-4d23-bd84-97d7440ee525?source=cve).
# WP-CLI on the server.
wp plugin update wp-all-export-drag-drop-export-to-any-custom-csv-xml-excel 

# If you cannot patch right now, deactivate the plugin.
wp plugin deactivate wp-all-export-drag-drop-export-to-any-custom-csv-xml-excel

# Verify the running plugin version.
wp plugin get wp-all-export-drag-drop-export-to-any-custom-csv-xml-excel --field=version

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.wordfence.com/threat-intel/vulnerabilities/id/9a92c682-b8b3-4d23-bd84-97d7440ee525?source=cve

# 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

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 unusually long URI paths containing traversal sequences, unexpectedly large responses from the affected endpoint, and outbound requests from the application to internal addresses or cloud-metadata endpoints. Treat any sensitive file the bug could disclose as exposed.

Frequently asked questions

Is CVE-2026-1582 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-2026-1582?

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 WP All Export – Drag & Drop Export to Any Custom CSV, XML & Excel 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.
