The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

Exploitation requires only that the target site runs the Booking Package WordPress plugin at a version before 1.7.31 with its premium/paid features in use; the vulnerable subscription-reset code path performs no authorization or validity check, so no authentication, no user interaction, and no non-default configuration are needed (PR:N/UI:N). The practical limiting factor is impact scope rather than access: the attack only resets premium subscription state to disable paid features and cannot read data, alter bookings' confidentiality, or take the site offline. Realistic risk is therefore bounded to sites actually relying on the plugin's paid tier.

Impact

All signals point to a genuine but low-severity, limited-impact vulnerability rather than a high-priority emergency. The provided CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) confirms remote, unauthenticated, low-complexity exploitation with no user interaction, which maximizes exploitability, but the impact metrics (C:N/I:L/A:N) are deliberately modest: the only consequence is an integrity change (resetting the premium subscription state to disable paid features), with no confidentiality or availability loss and an unchanged scope. This yields the 5.3 MEDIUM score and matches CWE-862 (Missing Authorization). Publicly available exploit code exists (WPScan), which raises the practical likelihood of opportunistic abuse, but the vulnerability is NOT in CISA KEV and no EPSS probability was supplied, so there is no evidence of active, widespread exploitation. No SSVC decision data was provided. In short: easy to trigger but low-value to an attacker (it sabotages a site's paid features rather than granting data access or code execution), so treat as a routine patch priority, not a critical incident. EPSS and KEV data are both absent/negative, consistent with a nuisance-grade flaw rather than a mass-exploited one.

Exploit ScenarioDerived

A remote, unauthenticated attacker sends a crafted request to a vulnerable WordPress site running Booking Package before 1.7.31, invoking the subscription-reset function that lacks any authorization or validity check. This resets the plugin's premium subscription state and disables the site's paid booking features, degrading functionality for the site operator. Public exploit code is available via WPScan, lowering the skill barrier to abuse.

AnalysisAIv1 – Oct 21, 2026

Booking Package WordPress plugin before 1.7.31 allows unauthenticated remote attackers to reset its premium subscription state, disabling paid features on affected sites. The issue is a missing authorization and validity check in the subscription-reset code path, requiring no credentials or user interaction, and is limited to integrity impact on the plugin’s premium status. Publicly available exploit code exists, and the vendor has released version 1.7.31 to address the flaw; risk is bounded to sites actively using the paid tier.

RemediationAI

Vendor-released patch: update the Booking Package WordPress plugin to version 1.7.31 or later via the WordPress dashboard or the vendor/WPScan advisory at https://wpscan.com/vulnerability/feb9d9bd-7192-4c75-9dc4-43d925518dc1/. If immediate patching is not possible, consider temporarily disabling the plugin’s premium/paid features until the update can be applied, with the trade-off that paid functionality will be unavailable; alternatively, restrict access to the plugin’s subscription-reset endpoint using a WAF or server-side rule, recognizing that overly broad blocking may interfere with legitimate subscription management. Deactivating the Booking Package plugin entirely removes exposure but also disables all booking functionality on the site.

Technical ContextAI · show details

Booking Package is a WordPress plugin, and the affected code path handles resetting its premium subscription state. The root cause is CWE-862 (Missing Authorization): the subscription-reset logic does not verify the requester’s authorization or validate the request before changing premium status. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N indicates a network-reachable, low-complexity issue with no privileges or user interaction required, but with only low integrity impact and no confidentiality or availability impact. The CPE entry cpe:2.3:a:unknown:booking_package:*:*:*:*:*:*:*:* identifies the affected plugin family without a resolved vendor namespace, while EUVD lists affected versions as Booking Package 0 through versions before 1.7.31. Public exploit code is available, but there is no CISA KEV confirmation in the provided data.
