CVE-2025-12171: RESTful Content Syndication 1.1.0 - 1.5.0 - Authenticated (Contributor+) Arbitrary File Upload

• Severity: high (CVSS 8.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2025-11-01 · updated 2026-10-18
• Weakness: CWE-434

Description

The RESTful Content Syndication plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the ingest_image() function in versions 1.1.0 to 1.5.0. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. This requires the attacker have access to a defined third-party server as specified in the settings, so it is unlikely that this will be exploitable by contributor-level users, and more likely to be exploited by administrators who also have access to the plugin's settings.
