CVE-2026-17559 (GCVE-0-2026-17559)

Vulnerability from nvd – Published: 2026-08-21 11:40 – Updated: 2026-08-21 12:47

Title

Content Protector (Passster) < 4.3.9 - Unauthenticated Protected Content Disclosure via REST Path Allowlist Bypass

Summary

The Passster WordPress plugin before 4.3.9 does not correctly match its own public endpoint paths when deciding which REST API requests may bypass global password protection, comparing them as an unanchored substring of the request URI rather than against the resolved route, allowing an unauthenticated attacker to read the content of globally password-protected posts and pages.

Severity

5.3 (Medium)

CVE-2026-17559 (GCVE-0-2026-17559)

Vulnerability from cvelistv5 – Published: 2026-08-21 11:40 – Updated: 2026-08-21 12:47

Title

Content Protector (Passster) < 4.3.9 - Unauthenticated Protected Content Disclosure via REST Path Allowlist Bypass

Summary

The Passster WordPress plugin before 4.3.9 does not correctly match its own public endpoint paths when deciding which REST API requests may bypass global password protection, comparing them as an unanchored substring of the request URI rather than against the resolved route, allowing an unauthenticated attacker to read the content of globally password-protected posts and pages.

Title

Content Protector (Passster) < 4.3.7 - Contributor+ Protected Content Disclosure via Core REST API

Summary
