Unauthenticated Access Control Bypass in PowerPress Podcasting

Unauthenticated Broken Access Control in PowerPress Podcasting <= 11.17.9 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-2026-104387 represents a critical broken access control vulnerability affecting PowerPress Podcasting plugin versions 11.17.9 and earlier. This unauthenticated flaw allows attackers to bypass authorization checks and gain unauthorized access to sensitive podcast management functions without valid credentials. WordPress site administrators running vulnerable versions face immediate risk, as threat actors can exploit this weakness to modify podcast content, steal listener data, inject malicious episodes, or pivot to deeper site compromise. The high CVSS score of 7.2 reflects the severity—attackers need no authentication or user interaction to trigger the vulnerability, making it trivial to exploit at scale.

Casky's 283 mapped skills leverage Claude AI's extended reasoning to detect exploitation patterns across MITRE ATT&CK tactics TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners using Casky will identify attack chains where adversaries initially probe for access control weaknesses (CWE-862 detection), then escalate privileges to administrative podcast functions without authentication. Security teams will see findings flagging suspicious unauthenticated requests to podcast configuration endpoints, unauthorized content modifications, and lateral movement indicators within WordPress environments—all correlated to the specific techniques and sub-techniques that PowerPress exploitation typically employs. This intelligence enables practitioners to prioritize patch deployment and implement compensating controls like WAF rules targeting the vulnerable endpoints.
