WPO365 Broken Access Control Allows Unauthorized Subscriber Access

Subscriber Broken Access Control in WPO365 <= 44.1 versions.

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2026-102915 represents a critical broken access control vulnerability in WPO365 versions 44.1 and earlier, where insufficient authorization checks allow attackers to gain unauthorized access to subscriber resources and functionality. This vulnerability is particularly dangerous because WPO365 is widely used for Microsoft 365 integration in WordPress environments, making it a high-value target for threat actors seeking to compromise organizational data and accounts. Organizations running affected versions face immediate risk of privilege escalation, data exfiltration, and lateral movement within their Microsoft 365 tenants, with the CVSS 8.5 rating reflecting the severity of potential impact.

Casky's 283 mapped security skills leverage Claude AI with extended reasoning to detect the attack patterns underlying this vulnerability across MITRE ATT&CK techniques TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners using Casky would identify detection opportunities such as: unusual subscriber account access patterns inconsistent with user roles, API calls bypassing authorization validation checks, access to high-privilege resources from unexpected subscriber contexts, and anomalous changes to subscription permissions or entitlements. The platform's skills help security teams recognize the specific authorization bypass indicators and access control failures that characterize this vulnerability, enabling them to hunt for exploitation attempts and rapidly validate whether their WPO365 deployments have been compromised before attackers escalate privileges or harvest credentials at scale.
