Unauthenticated PHP Object Injection in RegistrationMagic <= 6.0.9.7 versions.
Articles & Coverage 1
AnalysisAI
Unauthenticated PHP Object Injection in the RegistrationMagic WordPress plugin (versions <= 6.0.9.7) allows remote attackers to inject crafted serialized PHP objects that are deserialized by the application without validation. Depending on the POP gadget chains available in the plugin, WordPress core, or other installed plugins, this can escalate to arbitrary file operations, SQL injection, or remote code execution. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires reaching a RegistrationMagic input that is deserialized via unserialize() - in practice a registration/submission form or request parameter exposed by the plugin on a site running RegistrationMagic <= 6.0.9.7. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, 9.8 critical) indicates network-reachable, low-complexity, unauthenticated exploitation with full CIA impact - a maximal theoretical severity. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker submits a crafted serialized PHP object through a RegistrationMagic form field or request parameter that the plugin later passes to unserialize(). When deserialized, the payload triggers a magic method that fires a POP gadget chain present in the WordPress environment, letting the attacker write files, read sensitive data, or execute code - all without credentials given the AV:N/AC:L/PR:N vector. … |
| Remediation | Upgrade RegistrationMagic to a version later than 6.0.9.7 once released by Metagauss; the input identifies 6.0.9.7 as the last vulnerable version but does not confirm an exact patched release number, so consult the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/custom-registration-form-builder-with-submission-manager/vulnerability/wordpress-registrationmagic-plugin-6-0-9-7-php-object-injection-vulnerability) for the fixed version - Patch availability per vendor advisory; released patched version not independently confirmed from the provided data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Audit all WordPress instances to identify installations of RegistrationMagic versions 6.0.9.7 or earlier and immediately disable or uninstall the plugin from affected sites if functionally feasible. …
