Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Requires timely remediation of the specific deserialization flaw in the Events Calendar for GeoDirectory plugin through patching to versions beyond 2.3.14.

SI-10 Information Input Validation good match

prevent

Mandates validation of untrusted inputs to block malicious serialized data from being deserialized, directly countering CWE-502 object injection.

RA-5 Vulnerability Monitoring and Scanning partial match

detect

Enables vulnerability scanning to identify and prioritize the deserialization vulnerability in the WordPress plugin for remediation.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

NVD Description

Deserialization of Untrusted Data vulnerability in Stiofan Events Calendar for GeoDirectory events-for-geodirectory allows Object Injection.This issue affects Events Calendar for GeoDirectory: from n/a through <= 2.3.14.

Deeper analysisAI

CVE-2025-26967 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the Events Calendar for GeoDirectory WordPress plugin by Stiofan, which allows Object Injection. The issue affects the plugin in all versions from n/a through 2.3.14.

Attackers with low privileges (PR:L), such as authenticated users, can exploit this vulnerability over the network (AV:N) with low complexity (AC:L) and no user interaction (UI:N), without changing scope (S:U). Successful exploitation can result in high impacts to confidentiality, integrity, and availability (C:H/I:H/A:H), as reflected in the CVSS v3.1 base score of 8.8.
