CVE-2025-62740: 
WordPress vulnerability analysis and mitigation

CVE-2025-62740 is a Missing Authorization (Broken Access Control) vulnerability in the WP-CRM System WordPress plugin developed by Mario Peshev. It affects all versions up to and including 3.4.6, allowing unauthenticated attackers to exploit incorrectly configured access control security levels. The vulnerability was reported by security researcher Legion Hunter on November 8, 2025, and published by Patchstack on December 8, 2025. It carries a CVSS v3.1 base score of 5.3 (Medium) (Patchstack).

The root cause is classified as CWE-862 (Missing Authorization), meaning the plugin fails to perform adequate authorization, authentication, or nonce token checks on one or more functions. This allows an unauthenticated network attacker — with no privileges and no user interaction required — to invoke functionality that should be restricted to higher-privileged users. The attack vector is network-based with low complexity, making it straightforward to exploit remotely. No detailed technical write-up or public proof-of-concept code has been identified at this time (Patchstack).

Successful exploitation results in a low integrity impact, allowing unauthenticated attackers to perform unauthorized actions within the WP-CRM System plugin that should require elevated privileges. Confidentiality and availability are not directly impacted according to the CVSS assessment. While the severity is rated medium, Patchstack notes that vulnerabilities of this class are commonly used in mass-exploit campaigns targeting thousands of WordPress sites simultaneously, regardless of site size or popularity (Patchstack).

No public proof-of-concept exploit code or confirmed in-the-wild exploitation has been reported for CVE-2025-62740. The EPSS score is approximately 0.017%, indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack classifies the priority as "Low" and notes the issue is unlikely to be exploited, though the unauthenticated, network-accessible nature of the flaw means it could be incorporated into automated WordPress scanning campaigns (Patchstack).

As of the disclosure date, no official patch has been released by the plugin developer for WP-CRM System. The immediate recommended action is to update the plugin if a patched version becomes available, or to deactivate and remove the plugin until a fix is issued. Site administrators unable to patch should consult their hosting provider or web developer, and may consider using a WordPress security solution such as Patchstack to apply virtual patching as a temporary mitigation (Patchstack).
