Unauthenticated PHP Object Injection in FundEngine <= 1.7.9 versions.
Articles & Coverage 1
AnalysisAI
Unauthenticated PHP Object Injection in the FundEngine WordPress fundraising/donation plugin (slug wp-fundraising-donation) affects all versions up to and including 1.7.9, letting a remote attacker with no authentication inject a crafted serialized PHP object into an application deserialization sink. Given the CWE-502 root cause and the PR:N/UI:N vector, a successful attack can pivot to remote code execution, data theft, or full site takeover when a suitable POP gadget chain is reachable. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The prerequisite is that a vulnerable FundEngine (wp-fundraising-donation) version ≤ 1.7.9 is installed and active on a reachable WordPress site, exposing the endpoint that feeds untrusted input into PHP unserialize(); per AV:N/AC:L/PR:N/UI:N this is remote, unauthenticated, and requires no user interaction against default configurations. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals point to a genuine high priority rather than an inflated score: the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N, C:H/I:H/A:H, base 9.8) describes remote, unauthenticated, low-complexity exploitation with full impact, and PHP object injection in a publicly reachable WordPress plugin endpoint is a well-understood and readily weaponizable pattern. … 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 a public FundEngine endpoint with a malicious serialized PHP object as a parameter value; when the plugin deserializes it, a POP gadget chain assembled from loaded PHP classes executes, letting the attacker write files, manipulate the database, or run code to take over the site. Because the vector is AV:N/AC:L/PR:N/UI:N, no credentials, user interaction, or unusual conditions are required, making the request trivial to automate. … |
| Remediation | No specific fixed version is provided in the supplied intelligence, so treat patch status as: no vendor-released fixed version independently confirmed at time of analysis - consult the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/wp-fundraising-donation/vulnerability/wordpress-fundengine-plugin-1-7-9-php-object-injection-vulnerability?_s_id=cve) and the WordPress plugin page for a release above 1.7.9 and upgrade as soon as one is confirmed. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all WordPress instances running FundEngine and immediately deactivate the plugin, or implement temporary access controls to restrict its use to authenticated administrators only. …
