AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Network-reachable plugin endpoint (AV:N, AC:L) requires a low-privilege authenticated account (PR:L), no interaction (UI:N); object injection can yield full RCE-level C/I/A:H within an unchanged scope.

Deserialization of Untrusted Data vulnerability in Vektor Inc. VK Google Job Posting Manager vk-google-job-posting-manager allows Object Injection.This issue affects VK Google Job Posting Manager: from n/a through 1.3.1.
Articles & Coverage 1
AnalysisAI
PHP object injection in the VK Google Job Posting Manager WordPress plugin (versions through 1.3.1) allows an authenticated low-privilege user to submit crafted serialized input that the plugin deserializes without validation, permitting object injection that can escalate to arbitrary code execution, file manipulation, or sensitive data exposure where a usable gadget chain exists in the plugin or its loaded libraries. Per the CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, base 8.8), the flaw is network-reachable with low complexity, requires only low-level authentication, and needs no user interaction, resulting in high confidentiality, integrity, and availability impact. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires a running instance of the VK Google Job Posting Manager WordPress plugin at version 1.3.1 or earlier, and a low-privilege authenticated WordPress account (PR:L) capable of reaching the vulnerable deserialization entry point; no user interaction is needed (UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The input CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, base 8.8) describes a network-reachable, low-complexity PHP Object Injection flaw requiring only low-level authentication (PR:L) and no user interaction, with high confidentiality, integrity, and availability impact - consistent with CWE-502 deserialization leading to code execution in the WordPress context. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch was identified at time of analysis, and the available data does not publish a fixed version, so the safest immediate action is to deactivate and remove VK Google Job Posting Manager from any site that does not strictly need it - the plugin is a specialized job-posting/schema component and its removal has limited operational impact. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all WordPress instances for VK Google Job Posting Manager versions through 1.3.1, deactivate and remove the plugin where business requirements allow, and if it must remain active, immediately restrict low-privilege account creation by disabling open registration, auditing and removing unused subscriber or other low-privilege accounts, and limiting plugin management to trusted administrators; deploy WAF or virtual patching rules to block serialized object payloads targeting the plugin. …
