Vulnerability CVE-2026-13001: arbitrary file loads

The CVE-2026-13001 vulnerability affects the Podlove Podcast Publisher plugin forWordPressand allows unauthenticated attackers to upload arbitrary files to the affected site server.

If an attacker manages to upload a malicious file to the site’s server, it can be executed and can allow the attacker to gain unauthorized access to the site. This can lead to theft of sensitive data, modifying the site’s content, or even compromising the entire site.

Our recommendation for fixing this vulnerability is to update the Podlove Podcast Publisher plugin to the latest version, which contains patches for this vulnerability. It is also recommended to regularly check the files uploaded to the site to detect and prevent malicious file uploads.

If an attacker manages to bypass SAML authentication, he may gain unauthorized access to the site, including administrator accounts. This can lead to theft of sensitive data, modification of site content, or even compromise the entire site.

Our recommendation for fixing this vulnerability is to update the SAML Single Sign On – SSO Login plugin to the latest version, which contains patches for this vulnerability. It is also recommended to regularly check the SAML configuration to detect and prevent bypassing authentication.
