• Severity: medium (CVSS 5.4 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-01-24 · updated 2026-06-17
• Weakness: CWE-79

Description

The Same Category Posts plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the widget title placeholder functionality in all versions up to, and including, 1.1.19. This is due to the use of `htmlspecialchars_decode()` on taxonomy term names before output, which decodes HTML entities that WordPress intentionally encodes for safety. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
