What is CVE-2026-15979?
CVE-2026-15979 is a high-severity path traversal vulnerability in keywordrush Content Egg – Affiliate Product Importer & Price Comparison, published on 5 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
