CVE-2026-24636 is a medium-severity vulnerability affecting Syed Balkhi Sugar Calendar (Lite). This vulnerability allows for the exploitation of incorrectly configured access control security levels, which could lead to unauthorized access to sensitive functionalities. The issue primarily affects versions up to 3.9.1 of the Sugar Calendar (Lite). The CVSS score for this vulnerability is 4.3, indicating a moderate risk for organizations utilizing this plugin.
Risk to organizations includes potential unauthorized access to user data and functionalities within the Sugar Calendar (Lite) application. Given its medium severity, organizations should address this vulnerability in their patching cycle to minimize the risk of exploitation.
Currently, there are no known exploits publicly available for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, the absence of a known exploit does not diminish the importance of remediation, as attackers may still identify ways to exploit this vulnerability.
Organizations should prioritize patching immediately. The best practice is to upgrade to the latest version of the Sugar Calendar (Lite) plugin to mitigate the risk associated with this vulnerability.
Vulnerability Details
The official CVE description states that this vulnerability is characterized as a missing authorization issue, classified under CWE-862. Specifically, it allows attackers to exploit incorrectly configured access control security levels within the Sugar Calendar (Lite) plugin. The affected versions range from n/a to 3.9.1, with a CVSS score of 4.3 indicating a medium severity. This vulnerability was published on January 23, 2026.
Technical Analysis
The root cause of CVE-2026-24636 lies in the missing authorization checks within the Sugar Calendar (Lite) plugin. This misconfiguration allows unauthorized users to gain access to functionalities that should be restricted. The attack vector is network-based, meaning an attacker can exploit this vulnerability remotely without physical access to the system.
The attack complexity is considered low, and the privileges required for exploitation are also low, meaning that even users with minimal access could potentially exploit this issue. User interaction is not necessary for the exploitation of this vulnerability, which further increases its risk profile. The confidentiality impact is none, while the integrity impact is low, indicating that although unauthorized access is possible, the attacker may not be able to alter data significantly.
Risk & Impact Analysis
Real-world deployment of this vulnerability poses a risk to organizations using the Sugar Calendar (Lite) plugin. If exploited, unauthorized users could access sensitive functionalities and potentially compromise user data. The blast radius could extend to all users of the affected versions, making the impact significant.
Given the CVSS score of 4.3, organizations should address this vulnerability in their priority patch cycle. The absence of known exploitation in the KEV catalog should not deter organizations from taking immediate action to remediate.
