Is Content Egg safe? Known vulnerabilities and latest version

The Content Egg plugin for WordPress is vulnerable to unauthorized modification of data due to a missing per-post capability check on the ajaxUpdateProducts() function in versions up to, and including, 12.0.0. The handler verifies a static nonce ('contentegg_metabox') and the generic 'edit_posts' capability, but trusts the attacker-supplied $_POST['post_id'] verbatim and never calls current_user_can('edit_post', $post_id) — the per-object check that its sibling save_post handler saveMeta() correctly performs. This makes it possible for authenticated attackers, with contributor-level access and above, to modify Content Egg product data (_cegg_data_*) and update-timestamp post meta on arbitrary posts, including those owned by administrators.

The Content Egg – Affiliate Product Importer & Price Comparison plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 12.0.0 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with author-level access and above, to create posts attributed to another user's account — typically an administrator — by supplying an admin-owned preset_id, causing wp_insert_post to record the administrator as post_author. This includes the ability to create published posts when the attacker already holds publish_posts capability for the preset's post type, resulting in administrator-attributed published content created by a lower-privileged user.

Shop manager PHP Object Injection in Content Egg <= 6.3.1 versions.

The Content Egg WordPress plugin before 11.9.0 does not verify that a user running its bulk content-import feature is authorized for the import preset they select, and switches to the preset author's identity before creating the resulting post, allowing users with contributor-level access and above to store arbitrary web scripts unfiltered under a privileged user's account, executing in the context of anyone who later views that content.

The Content Egg – Affiliate Product Importer & Price Comparison plugin for WordPress is vulnerable to Arbitrary File Deletion via Path Traversal in versions up to and including 11.3.0. This is due to insufficient validation of the 'img_file' field within the cegg_data post metadata: the value passes only through wp_strip_all_tags() (which does not strip path traversal sequences), is stored directly in post meta, and is later concatenated without normalization into a filesystem path in getFullImgPath() before being passed to PHP's unlink(). This makes it possible for authenticated attackers, with author-level access and above, to delete arbitrary files on the affected site's server which may make remote code execution possible.

Deserialization of Untrusted Data vulnerability in keywordrush Content Egg content-egg allows Object Injection.This issue affects Content Egg: from n/a through <= 7.0.0.

Cross-Site Request Forgery (CSRF) vulnerability in Keywordrush Content Egg plugin <= 5.4.0 on WordPress.
