CVE-2026-15979
At a glance
CVE-2026-15979 is a high-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Content Egg WordPress plugin, affecting versions <= 11.3.0. It carries a CVSS score of 8.1 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires an authenticated account at Author level or above. The issue is fixed in version 11.4.0; sites on affected versions should update now. Disclosed August 2026, reported by Athiwat Tiprasaharn (Jitlada).
Vulnerability Overview
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.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on integrity, availability.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Content Egg <= 11.3.0 carries this weakness at img_file, and reaching it takes an account at Author level or above. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.
Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For Content Egg the fix is 11.4.0: builds <= 11.3.0 are affected, anything from 11.4.0 onward is not.
Remediation
Update to version 11.4.0, or a newer patched version
How WordSec helps
An attacker needs Author access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Content Egg 11.4.0 closes this, and updating the plugin is the step that ends it.
