CVE-2025-23636: High Vulnerability in Dimitar A. My Favorite Car

CVE-2025-23636 is classified as a high-severity vulnerability due to improper neutralization of input during web page generation, specifically resulting in reflected Cross-site Scripting (XSS) in the My Favorite Car plugin developed by Dimitar A. This vulnerability affects versions of My Favorite Car up to and including 1.0. Given its nature, this vulnerability poses a significant risk to organizations using this plugin.

With a CVSS score of 7.1, the vulnerability is characterized by a low attack complexity and does not require any privileges for exploitation. However, user interaction is required, making it an enticing target for attackers who may leverage social engineering techniques to exploit this flaw. The urgency for defenders is underscored by the potential for unauthorized access and data exposure.

Currently, there is no known public exploit for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) list. Nevertheless, organizations should remain vigilant, as the absence of known exploits does not mitigate the risk presented by this vulnerability.

Organizations should prioritize patching immediately to address this vulnerability and review their security practices regarding user input handling to prevent similar issues in the future.

Vulnerability Details

The official CVE description states that this vulnerability allows for improper neutralization of input during web page generation, leading to reflected XSS in the My Favorite Car plugin. The CVSS score of 7.1 indicates a high-severity vulnerability with low attack complexity and no privileges required. The affected product is the My Favorite Car plugin, with the vulnerability disclosed on January 23, 2025.

The vulnerability is associated with CWE-79, which pertains to improper neutralization of input during web page generation. Given the potential for exploitation, action must be taken to remediate this issue promptly.

Technical Analysis

The root cause of CVE-2025-23636 lies in the inadequate sanitization of user inputs. Attackers may exploit this vulnerability by crafting malicious inputs that the application processes without proper validation. The attack vector is primarily network-based, allowing attackers to target users remotely.

The attack complexity is classified as low, meaning that an attacker can exploit this vulnerability with minimal effort. No privileges are required, and user interaction is necessary, which often involves tricking a user into clicking a link or submitting data to a malicious site.

The confidentiality, integrity, and availability impacts are all rated as low, indicating that while the potential for damage is present, the extent of the damage from exploitation may be limited. However, organizations must consider the impact of potential data exposure and unauthorized actions that could arise from successful exploitation.

Risk & Impact Analysis

Organizations utilizing the My Favorite Car plugin face real-world deployment risks due to this vulnerability. Attackers may leverage this flaw to perform XSS attacks, potentially gaining access to sensitive user data or executing unauthorized actions on behalf of users. The risk to organizations includes loss of data integrity, exposure of sensitive information, and damage to reputation.

The urgency of addressing this vulnerability is heightened by the current threat landscape. As organizations increasingly rely on web applications for customer interactions, vulnerabilities like CVE-2025-23636 can be exploited to devastating effect. Organizations should conduct a thorough risk assessment and take immediate action to patch vulnerable systems.

Affected Versions

The vulnerability affects My Favorite Car plugin versions from n/a to 1.0. Organizations utilizing any of these versions are at risk and should act swiftly to implement patches or updates.

Mitigation & Remediation

To mitigate the risks associated with CVE-2025-23636, organizations should ensure they upgrade to the latest version of the My Favorite Car plugin. If a patch is not available, consider implementing input validation and sanitization measures to mitigate the risk of XSS attacks.
