Exploitation Conditions

Exploitation requires an authenticated account possessing the AWP Classifieds plugin's management capability (per CVSS PR:L), use of the plugin's listing-import feature which accepts an uploaded ZIP archive, and that the plugin extracts archive contents - without validating file type (CWE-434) - into a publicly accessible, network-shared directory from which the planted PHP can be requested and executed. Limiting factors: the attacker must already hold that privileged capability (not a default unauthenticated visitor), the vulnerable version must be <4.4.9 (patched in 4.4.9), and successful RCE depends on the extraction directory being web-reachable and PHP execution being permitted there. These constraints reduce realistic exposure despite the high CVSS base score.

Impact

This is a genuine but conditionally-gated high-severity issue rather than a mass-exploitation emergency. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N) yields 8.8 and reflects network reach with low complexity and no user interaction, but it requires PR:L - the attacker must already hold the plugin's management capability, which materially narrows the attacker population to authenticated, privileged plugin operators. CWE-434 plus the described write of arbitrary PHP to a publicly-reachable directory supports the SSVC 'Technical Impact: total' rating, consistent with C:H/I:H/A:H. Signals are coherent but point to limited scale: SSVC marks Exploitation as 'none' and Automatable as 'no', and EPSS is only 0.19% (8th percentile), indicating low predicted real-world exploitation volume. This CVE is NOT in CISA KEV, so there is no confirmed active exploitation. A public exploit (WPScan) does exist, but POC availability is distinct from active exploitation and should not be read as 'in the wild.' Net: a real priority for sites running the vulnerable plugin where the management capability is delegated to semi-trusted or compromisable accounts, but the PR:L gate and low EPSS/SSVC-automatable signals argue against treating it as an unauthenticated internet-wide threat.

Exploit ScenarioDerived

An authenticated user holding the AWP Classifieds management capability uses the plugin's listing-import feature to upload a ZIP archive containing a malicious PHP file; because the plugin does not validate extracted file types, the PHP file lands in a publicly accessible, network-shared directory. The attacker then requests that file's URL directly to execute arbitrary code on the server. A public exploit for this flaw is available via WPScan, lowering the effort to reproduce it.

AnalysisAIv1 – Oct 09, 2026

Remote code execution in the AWP Classifieds WordPress plugin before 4.4.9 allows an authenticated user holding the plugin's management capability to import a crafted ZIP archive whose contents are extracted without file-type validation, planting arbitrary PHP into a publicly accessible, network-shared directory. Because the extraction target is web-reachable, the uploaded PHP can be requested and executed, yielding code execution under the web server account. Exploitation is gated by the required management capability (CVSS PR:L), and a vendor patch is available in 4.4.9; publicly available exploit code exists and EPSS is low at 0.19% (8th percentile), with no CISA KEV listing indicating confirmed active exploitation. CWE-434 (unrestricted upload of a file with a dangerous type) is the root cause class.

RemediationAI

Upgrade the AWP Classifieds WordPress plugin to version 4.4.9 or later, which is the vendor-released patch that resolves the issue (Vendor-released patch: 4.4.9); verify the installed version under the WordPress plugins screen and confirm the update via the WPScan advisory at https://wpscan.com/vulnerability/6d3e7721-41d4-4e5f-9a44-c601f0cdfe50/. If upgrading is not immediately possible, compensate by tightly restricting which accounts hold the plugin's management capability (since exploitation requires an authenticated user with that privilege, per PR:L) and by temporarily disabling or restricting access to the listing-import feature - accepting the trade-off that imports must be performed manually or deferred. Confirm that the directory used for extraction is not web-reachable and that PHP execution is disabled there (e.g., via server configuration), noting that these hardening measures may break legitimate listing-import functionality if the plugin depends on serving extracted content from that path. Review logs for unauthorized ZIP uploads or unexpected PHP files in the import directory, and treat any such artifacts as indicators of a potential compromise that warrants further investigation.

Technical ContextAI · show details

The flaw resides in the listing-import feature of the AWP Classifieds WordPress plugin, which accepts an uploaded ZIP archive and extracts its contents server-side. The extraction routine does not validate the type of the extracted files (CWE-434), so an archive containing .php files is unpacked as-is. The plugin places extracted files into a publicly accessible, network-shared directory rather than a hardened or non-executable location, meaning the attacker-supplied PHP can subsequently be requested over HTTP and executed by the web server. The affected component is the WordPress plugin 'awp_classifieds' (CPE cpe:2.3:a:unknown:awp_classifieds:*:*:*:*:*:*:*:*; EUVD lists affected range 0 to <4.4.9). Exploitation prerequisites align with the assessed CVSS 3.1 vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H: the attacker must already possess the plugin's management capability, the vulnerable version must be below 4.4.9, and successful RCE additionally depends on the extraction directory being web-reachable and PHP execution being permitted there.

Executive ViewAI

Why It Matters

AWP Classifieds WordPress plugin versions prior to 4.4.9 contain a high-severity remote code execution vulnerability that allows an authenticated user with plugin management capabilities to upload and execute arbitrary PHP code, potentially leading to full website compromise. Although exploitation requires authenticated access, affected organizations face risks of data theft, website defacement, malware distribution, and reputational damage if their WordPress sites run this plugin; leadership should prioritize patching to mitigate potential business disruption and compliance implications.
