AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Title scopes exploitation to authenticated Subscriber accounts, so PR:L not PR:N; remote network sink with low complexity and unsafe deserialization yields high C/I/A.

Subscriber PHP Object Injection in Uncanny Automator Pro <= 7.3.0.6 versions.
Articles & Coverage 2
AnalysisAI
PHP Object Injection in the Uncanny Automator Pro WordPress plugin (versions <= 7.3.0.6) allows authenticated users holding only the low-privileged Subscriber role to inject crafted serialized PHP objects into an unsafe deserialization sink (CWE-502). Depending on the gadget chains present in the plugin or co-installed software, this can escalate to remote code execution, arbitrary file operations, or database tampering. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated account at the WordPress Subscriber role (the lowest standard role) - this is the explicit prerequisite stated in the vulnerability title, contradicting the input vector's PR:N. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals conflict and should be reconciled before prioritization. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers (or already holds) a Subscriber account on a WordPress site running Uncanny Automator Pro <= 7.3.0.6, then submits a crafted serialized PHP object to a plugin parameter that is passed to unserialize(). If a suitable gadget chain exists among the installed plugins, the injected object triggers attacker-chosen behavior on deserialization - potentially writing a webshell or executing code. … |
| Remediation | No vendor-released patch version was included in the provided data, so no fixed release can be independently confirmed here; consult the Patchstack advisory (URL above) for the patched version and upgrade to the first release above 7.3.0.6 once published. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all affected Uncanny Automator Pro installations (versions ≤7.3.0.6); disable the plugin immediately if not business-critical or restrict Subscriber role creation and access. …
