CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-12877 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Givewp Givewp. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 31% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to PHP Object Injection in all versions up to and including 3.19.2. The flaw stems from unsafe deserialization of untrusted input supplied through donation form fields such as 'firstName', allowing an attacker to inject a PHP object. A subsequent POP chain enables deletion of arbitrary files on the server, which can be leveraged for remote code execution. The issue is tracked as CWE-502 and received a CVSS 3.1 base score of 9.8.
Unauthenticated attackers can exploit the vulnerability remotely by submitting crafted donation-form data, achieving arbitrary file deletion and remote code execution without requiring authentication, user interaction, or special privileges.
Advisories note that version 3.19.3 contained only a partial fix, while a complete patch was not issued until 3.19.4. The referenced WordPress changeset and Wordfence threat-intel entry document the remediation steps, and the vendor was advised to switch to JSON encoding to eliminate future deserialization risks.
The EPSS score remains flat at a peak of 0.3342 with no material rise after disclosure.

Vulnerability Data
The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.19.2 via deserialization of untrusted input from the donation form like 'firstName'. This makes it possible…

for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to delete arbitrary files on the server that makes remote code execution possible. Please note this was only partially patched in 3.19.3, a fully sufficient patch was not released until 3.19.4. However, another CVE was assigned by another CNA for version 3.19.3 so we will leave this as affecting 3.19.2 and before. We have recommended the vendor use JSON encoding to prevent any further deserialization vulnerabilities from being present.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can uncover deserialization flaws before deployment.
Input validation directly stops deserialization of untrusted data by ensuring inputs are valid before processing.
Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.
Integrity verification tools can detect malformed or tampered serialized data after the fact.

PR.PS-02 addresses only post-deployment updates/patching and cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.
