Unauthenticated PHP Object Injection in WP Project Manager <= 4.0.6 versions.
Articles & Coverage 1
AnalysisAI
Insecure deserialization in weDevs WP Project Manager (WordPress plugin) versions up to and including 4.0.6 allows remote unauthenticated attackers to inject crafted PHP objects (CWE-502) into the application. With CVSS:3.1 base score 9.8 (AV:N/AC:L/PR:N/UI:N) and full confidentiality, integrity, and availability impact, successful exploitation can lead to arbitrary object instantiation and, given a suitable POP gadget chain in the plugin or WordPress core, remote code execution or data compromise. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The affected weDevs WP Project Manager plugin (version <= 4.0.6) must be installed and active on the target WordPress site, and the vulnerable deserialization endpoint must be network-reachable. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals here are strong but partially unverified. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sends a crafted HTTP request to a public WordPress site running WP Project Manager <= 4.0.6, embedding a serialized PHP object in a parameter that the plugin passes to unserialize(). When deserialized, the forged object triggers a magic method that drives an available gadget chain, potentially leading to file manipulation, data disclosure, or code execution. … |
| Remediation | Update WP Project Manager to a release newer than 4.0.6 as soon as one is confirmed by weDevs; the input data specifies affected versions as <= 4.0.6 but does not include an exact fixed version, so no vendor-released patch version is independently confirmed at time of analysis - verify the fixed version against the vendor changelog and the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/wedevs-project-manager/vulnerability/wordpress-wp-project-manager-plugin-4-0-6-php-object-injection-vulnerability?_s_id=cve). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Immediately disable and remove weDevs WP Project Manager plugin from all WordPress installations; document any exported data and workflows for migration planning. …
