Unauthenticated network reach (PR:N/AV:N) but RCE depends on an available gadget chain (AC:H); impact stays within the WordPress process so S:U, with full C/I/A compromise.

The Remote API WordPress plugin through 0.2 does not authenticate a request before deserializing user-supplied input, allowing unauthenticated attackers to inject arbitrary PHP objects, which can lead to remote code execution when a suitable gadget chain is present through another installed Remote API WordPress plugin through 0.2.
Articles & Coverage 1
AnalysisAI
PHP object injection in the Remote API WordPress plugin (all versions through 0.2) lets unauthenticated attackers deserialize attacker-supplied input, and when a suitable gadget chain is available it escalates to remote code execution on the host. The flaw stems from the plugin processing serialized user input before any authentication check. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The reachable trigger requires no authentication and no user interaction: the plugin deserializes user-supplied input before authenticating the request, so any actor able to reach the Remote API endpoint over the network can inject arbitrary PHP objects against a default install of the plugin (versions ≤0.2). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed and warrant nuanced prioritization rather than blind CVSS-driven urgency. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker sends a crafted HTTP request to the plugin's remote API endpoint containing a serialized PHP payload; the plugin deserializes it without any auth check, instantiating attacker-chosen objects. If the WordPress install has a compatible gadget chain in a loaded plugin/theme/core, object lifecycle methods fire and execute the attacker's code on the server. … |
| Remediation | No vendor-released patch identified at time of analysis - the advisory covers all versions through 0.2 with no fixed version cited. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: conduct a comprehensive inventory of all WordPress instances to identify Remote API plugin versions 0.2 and below by scanning wp-content/plugins directories and WordPress database plugin tables. …
