CVE-2025-62138: 
WordPress vulnerability analysis and mitigation

CVE-2025-62138 is a Missing Authorization vulnerability in the CedCommerce WP Advanced PDF WordPress plugin that allows unauthenticated network attackers to exploit incorrectly configured access control security levels. It affects WP Advanced PDF versions from n/a through 1.1.7. The vulnerability was published on December 31, 2025, and assigned by Patchstack. It carries a CVSS v3.1 base score of 5.3 (Medium) (Feedly, EUVD).

The root cause is classified as CWE-862 (Missing Authorization), meaning the plugin fails to properly verify whether a requesting user has the necessary permissions before executing certain actions. The attack vector is network-based, requires no authentication, no user interaction, and low attack complexity, making it trivially exploitable by any remote attacker. The flaw stems from incorrectly configured access control security levels within the plugin's functionality, allowing unauthorized modification of data — likely related to PDF generation or management operations (Feedly, Patchstack).

Successful exploitation results in a low integrity impact with no confidentiality or availability impact. Unauthenticated attackers can alter PDF-related content or settings managed by the plugin without authorization, potentially enabling manipulation of generated documents on affected WordPress sites. While the impact is limited in scope (no data exfiltration or service disruption), unauthorized data modification could undermine trust in documents produced by the plugin (Feedly).

No public proof-of-concept exploit code or evidence of in-the-wild exploitation has been reported for CVE-2025-62138. The EPSS score is approximately 0.028% (0.000280), indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been identified (Feedly).

Users should update the WP Advanced PDF plugin to version 1.1.8 or later, which contains the fix for this missing authorization issue. As an interim measure, site administrators may consider disabling the plugin until the update can be applied. Restricting access to WordPress admin endpoints and monitoring plugin activity via a web application firewall (WAF) can provide additional defense-in-depth (Feedly, Patchstack).
