Summary

CVE-2023-46615 is a medium-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Kallidan Kd Coming Soon. Its CVSS base score is 5.4 (Medium).

Operationally, ranked in the top 9.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

The KD Coming Soon WordPress plugin, maintained by Kalli Dan and used to display coming-soon or maintenance pages, is affected by a deserialization of untrusted data vulnerability (CWE-502) in all versions through 1.7. The flaw is also tracked as a PHP object injection issue and carries a CVSS 3.1 score of 5.4.

An unauthenticated attacker can reach the vulnerable code over the network without credentials or user interaction, although successful exploitation requires high attack complexity and results in limited confidentiality and integrity impacts with scope change. The EPSS score has remained flat at 0.0559 with no material increase since disclosure.

Advisories published by Patchstack identify the affected plugin versions and link to the corresponding vulnerability record for further details on remediation. No information on observed in-the-wild exploitation is available in the provided data.

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-502

Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.

addresses: CWE-502

Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.

addresses: CWE-502

Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.

addresses: CWE-502

Validates or rejects untrusted serialized data before deserialization occurs.

addresses: CWE-502

Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.

addresses: CWE-502

Integrity verification of serialized information can detect tampering before deserialization occurs.

addresses: CWE-502

Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
