WP Event Solution CVE-2026-109898

No special configuration is required - the CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates remote, unauthenticated exploitation against default installations of the WP Event Solution plugin versions up to and including 4.1.25. The limiting factors are: the target site must have the vulnerable plugin installed and activated, and the real-world impact is constrained to limited integrity modification (C:N/A:N), so the flaw cannot be used to read sensitive data or cause denial of service by itself. Exact prerequisites (which specific endpoint or action lacks the authorization check) are not detailed in the provided description.

This is a genuinely moderate-to-low priority issue despite the 'medium' CVSS 5.3 rating. The CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates a network-reachable, low-complexity, unauthenticated flaw, which would normally raise concern, but the impact profile is narrow: C:N/I:L/A:N means no confidentiality or availability impact and only limited integrity impact - consistent with a CWE-862 Missing Authorization flaw that lets an unauthenticated actor invoke a function or modify limited state they should not reach. No EPSS score, SSVC decision data, KEV listing, or POC was provided in the input, so exploitation probability cannot be quantified from the data. There is no public exploit identified at time of analysis and no evidence of active exploitation. The signals are internally consistent (no CVSS-vs-description contradiction), so the main caveat is simply that this is a limited-integrity-impact access-control gap in a WordPress plugin rather than a high-impact RCE or data-exposure bug - prioritize patching but it does not warrant emergency response.

An unauthenticated remote attacker sends a crafted HTTP request directly to a plugin endpoint (e.g., an AJAX or REST action) that lacks a proper capability/authorization check, allowing them to trigger a privileged function or alter limited plugin data without logging in. Because CVSS shows AV:N/AC:L/PR:N/UI:N, no authentication, user interaction, or special timing is required. No public proof-of-concept exploit was identified in the provided data.
