The Podlove Podcast Publisher WordPress plugin is affected by a stored cross-site scripting (XSS) vulnerability via the Auphonic webhook endpoint in all versions up to and including 4.5.6. This vulnerability allows unauthenticated attackers to inject arbitrary scripts by submitting a crafted POST request where the status_string field is not 'Done'. The injected scripts execute when a user accesses the affected page, potentially leading to session hijacking or other malicious actions.
The Podlove Podcast Publisher plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'episode_contributor[..][..][comment]' Parameter in all versions up to, and including, 4.5.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The contributor comment is stored in a plugin-managed custom table, bypassing WordPress core's wp_kses_post filter, and the save_post hook fires without a nonce check, meaning any user who can edit posts can exploit this without further preconditions.
The Podlove Podcast Publisher plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the create_link_item function in all versions up to, and including, 4.5.3. This makes it possible for authenticated attackers, with contributor-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). A viable POP chain exists within the plugin itself via Podlove\ImageCache\GenerationGuard, whose __destruct() method invokes wp_delete_file() with an attacker-controlled file path populated through unserialization.
The Podlove Podcast Publisher WordPress plugin up to version 4.5.1 contains an improper input validation vulnerability in the 'podlove_handle_cache_files' function. This flaw allows unauthenticated attackers to upload arbitrary files to the server, potentially enabling remote code execution. The vulnerability is identified as CWE-20 and carries a critical CVSS score of 9.8.
The Podlove Podcast Publisher plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'move_as_original_file' function in all versions up to, and including, 4.2.6. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
The Podlove Podcast Publisher plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.2.2. This is due to missing or incorrect nonce validation on the ajax_transcript_delete() function. This makes it possible for unauthenticated attackers to delete arbitrary episode transcripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
The Podlove Podcast Publisher plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Feed Name value in version <= 4.1.25 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
The Archivist – Custom Archive Templates plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘shortcode_attributes' parameter in all versions up to, and including, 1.7.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
The Podlove Podcast Publisher plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the init_download() and init() functions in all versions up to, and including, 4.0.11. This makes it possible for unauthenticated attackers to export the plugin's tracking data and podcast information.
