CVE-2025-61872 is a medium-severity vulnerability affecting Mahara versions prior to 25.04.2 and 24.04.11. This vulnerability allows for cross-site scripting (XSS) attacks through the 'search site' feature when utilizing the Elasticsearch7 search plugin. The issue stems from the improper sanitization of input in the query parameter, enabling attackers to potentially execute malicious scripts in user browsers.
With a CVSS score of 6.1, this vulnerability poses a moderate risk to organizations using the affected versions of Mahara. The attack vector is network-based, with low complexity and no privileges required for exploitation, necessitating user interaction. Organizations should prioritize remediation to safeguard against potential attacks.
As of now, there are no known exploits or public proof of concepts, but the potential for exploitation exists due to the nature of XSS vulnerabilities. Consequently, organizations using vulnerable versions of Mahara should address this vulnerability immediately to mitigate risks.
Organizations should prioritize patching immediately. The risk to organizations includes the possibility of unauthorized actions being performed through a user's session, resulting in data theft or other malicious activities.
Vulnerability Details
The official CVE description indicates that Mahara before versions 25.04.2 and 24.04.11 are susceptible to XSS due to inadequate input sanitization in the Elasticsearch7 search plugin. This vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')).
CVSS v3.1 score for this vulnerability is 6.1, indicating a medium severity level. Organizations must closely monitor and remediate this vulnerability to prevent its exploitation. The vulnerability was published on April 24, 2026.
Technical Analysis
The root cause of CVE-2025-61872 lies in the failure of the Elasticsearch function to properly sanitize input in the query parameter for the search feature. This lack of sanitization enables attackers to inject malicious scripts into the application, which can then be executed by unsuspecting users.
The attack vector is network-based, meaning the attacker does not need physical access to the system. The complexity of the attack is low, requiring no special privileges, but necessitating user interaction to trigger the XSS payload. The potential impacts on confidentiality and integrity are low, but the availability impact is none.
Risk & Impact Analysis
Organizations using versions of Mahara that are impacted by this vulnerability face significant risks. The potential for unauthorized access through XSS attacks can lead to data breaches, loss of user trust, and regulatory repercussions. The urgency to address this vulnerability is underscored by its medium CVSS score, which indicates a moderate likelihood of exploitation.
Given the low attack complexity and the requirement for user interaction, organizations should consider the potential blast radius of this vulnerability. Attackers may exploit it to perform unauthorized actions in the context of a legitimate user, leading to serious operational impacts.

Affected Versions
The affected versions include Mahara before 25.04.2 and 24.04.11. Organizations should ensure they are running the latest versions to mitigate this vulnerability.
Mitigation & Remediation
Organizations should prioritize updates to Mahara versions 25.04.2 or later to address this vulnerability. If an immediate update is not feasible, consider implementing input validation and sanitization measures in the Elasticsearch plugin. Network controls should also be in place to restrict access to vulnerable components.
For further guidance on effective security practices, organizations can consult best practices on penetration testing methodology and other security assessments.
Detection Guidance
Organizations should monitor logs for any suspicious query parameters and user inputs that deviate from expected formats. Behavioral anomalies, such as unexpected script executions or redirects, should also be flagged and investigated. Additionally, network signatures related to the Elasticsearch functionality should be analyzed for potential exploitation attempts.
