Subscriber Arbitrary File Upload in Warehouse Cargo <= 2.6.9 versions.
AnalysisAI
Arbitrary file upload in the Warehouse Cargo WordPress theme (versions 2.6.9 and earlier) allows an authenticated subscriber-level user to upload malicious files, enabling remote code execution on the host. The flaw is remotely reachable and requires only the lowest privileged registered account, and its scope-changing CVSS 9.9 rating reflects potential full compromise of the underlying WordPress server. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated WordPress account at subscriber level or higher (CVSS PR:L), reachable over the network with no user interaction. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine high-priority issue rather than a paper-tiger high-CVSS score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a subscriber account on a Warehouse Cargo site that permits self-registration, then sends a crafted request to the theme's file-upload handler containing a PHP web shell disguised or unfiltered by type checks. Because no user interaction or higher privilege is needed, the shell lands in a web-accessible directory and the attacker browses to it to run arbitrary code as the web server user. … |
| Remediation | Update Warehouse Cargo to a release later than 2.6.9 once the vendor publishes one; the Patchstack advisory (https://patchstack.com/database/wordpress/theme/warehouse-cargo/vulnerability/wordpress-warehouse-cargo-theme-2-6-9-arbitrary-file-upload-vulnerability) is the authoritative source for the patched version, which is not independently confirmed in the data provided here, so verify the exact fix release with the vendor before relying on it. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: inventory all WordPress installations running Warehouse Cargo theme versions 2.6.9 or earlier; restrict subscriber account creation and disable file upload permissions for existing subscriber accounts; enable audit logging on all file upload activities. …
