Which versions of POS Entegratör are affected by CVE-2026-57688?

The POS Entegratör WordPress plugin (versions ≤3.7.103) contains a critical authorization bypass vulnerability allowing unauthenticated attackers to modify business-critical data without requiring…

How to fix or mitigate CVE-2026-57688?

24 hours: Audit all WordPress installations for POS Entegratör plugin versions ≤3.7.103; if operationally feasible, immediately deactivate and remove the plugin. If the plugin is mission-critical, restrict backend access via IP whitelisting and enable detailed logging of all administrative actions. 7 days: Deploy Web Application Firewall (WAF) rules to block unauthorized access to plugin functions; configure alerts for administrative access attempts and data modification events from unexpected sources. 30 days: Monitor vendor (gurmehub) advisory channels and WordPress.org plugin repository daily for security patch release; plan and execute upgrade to patched version within 48 hours of availability.

Unauthenticated Broken Access Control in POS Entegratör <= 3.7.103 versions.

AnalysisAI

Missing authorization in the POS Entegratör WordPress plugin (versions <= 3.7.103, vendor gurmehub) lets unauthenticated remote attackers reach privileged plugin functions that lack capability checks, enabling unauthorized modification of data with limited service disruption. The flaw is remotely reachable with no authentication or user interaction (CVSS 8.2), but has no confidentiality impact. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Technical ContextAI

The affected component is a third-party WordPress plugin (CPE cpe:2.3:a:gurmehub:pos_entegratör) that integrates point-of-sale systems with WordPress/WooCommerce sites, typically exposing AJAX or REST endpoints. The root cause is CWE-862 (Missing Authorization): one or more of the plugin's action handlers execute privileged operations without verifying the caller's capabilities or nonce/permission context. In WordPress plugins this class of bug commonly arises when handlers are hooked to public-facing endpoints (e.g. wp_ajax_nopriv_* or unauthenticated REST routes) without a current_user_can() check, so any anonymous visitor can invoke functionality intended only for authenticated/privileged users.

RemediationAI

No vendor-released patch version is identified in the provided data; the input only confirms versions <= 3.7.103 are vulnerable, so administrators should consult the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/pos-entegrator/vulnerability/wordpress-pos-entegratoer-plugin-3-7-103-broken-access-control-vulnerability) and upgrade to the next release that Patchstack/the vendor marks as fixed once available. Until a confirmed patched version is installed, the most effective compensating control is to deactivate and remove the POS Entegratör plugin, accepting loss of POS integration functionality; if it must stay active, restrict access to the plugin's endpoints at the web/WAF layer (for example, block or require authentication on the plugin's admin-ajax.php actions and any custom REST routes, and restrict by source IP to trusted POS/back-office hosts), with the trade-off that legitimate unauthenticated integrations or webhooks may break. A virtual patch via a WordPress WAF (such as Patchstack's own) can block exploit requests without a code change while you wait for an official fix.
