CVE-2026-25332: 
WordPress vulnerability analysis and mitigation

CVE-2026-25332 is a Missing Authorization (Broken Access Control) vulnerability in the WordPress plugin "Endless Posts Navigation" developed by Fahad Mahmood. It affects all versions up to and including 2.2.9, and was discovered by researcher Legion Hunter and reported on January 8, 2026, with public disclosure on February 7, 2026 via Patchstack. The vulnerability carries a CVSS v3.1 base score of 5.3 (Medium) (Patchstack, Feedly).

The root cause is classified as CWE-862 (Missing Authorization), meaning the plugin fails to properly verify whether a requesting user has the appropriate permissions before executing certain privileged actions. This allows unauthenticated, remote attackers to exploit incorrectly configured access control security levels via network-accessible endpoints, with no user interaction required. No authentication or elevated privileges are needed to trigger the flaw, making it trivially accessible to any remote attacker (Patchstack).

Successful exploitation results in a limited integrity impact — an unauthenticated attacker can perform actions that should be restricted to higher-privileged users, though there is no direct confidentiality or availability impact according to the CVSS scoring. The practical consequence is unauthorized modification or manipulation of plugin-controlled functionality on affected WordPress sites. While the individual impact per site is low, Patchstack notes that vulnerabilities of this type are commonly used in mass-exploit campaigns targeting thousands of WordPress sites simultaneously (Patchstack).

No public proof-of-concept exploit code or active in-the-wild exploitation has been confirmed for this vulnerability. The EPSS score is approximately 0.017%, indicating a low probability of exploitation in the near term. It is not currently listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack classifies this as low priority with unlikely exploitation, though the unauthenticated, network-accessible attack vector means it could be incorporated into automated WordPress scanning and exploitation tools (Patchstack).

The vendor has released version 2.3.0 of the Endless Posts Navigation plugin, which resolves this vulnerability. Site administrators should update to version 2.3.0 or later immediately via the WordPress plugin dashboard. If an immediate update is not possible, site owners should consult their hosting provider or web developer for assistance. Patchstack users can enable auto-update for vulnerable plugins as an additional safeguard (Patchstack).
