MyTube, a self-hosted downloader and player for various video websites, has a vulnerability identified as CVE-2026-24140. This vulnerability allows for a Mass Assignment issue in the settings management functionality, occurring in versions 1.7.78 and below. The root cause is insufficient input validation within the application's saveSettings() function, which accepts arbitrary key-value pairs without validating property names against allowed settings.
The saveSettings() function utilizes Record<string, any> as its input type and iterates through all entries using Object.entries() without filtering unauthorized properties. Consequently, any field sent by the attacker can be directly persisted to the database, irrespective of whether it corresponds to an actual application setting. This flaw has been resolved in version 1.7.78.
The CVSS score for this vulnerability is 2.7, classifying it as low severity. However, organizations should still recognize the potential risks associated with this vulnerability. With an attack vector of NETWORK and a low attack complexity, attackers may exploit this vulnerability if they have high privileges within the application.
Risk to organizations includes unauthorized data persistence, leading to potential data integrity issues. Therefore, organizations should prioritize patching immediately.
Currently, there are no known public exploits or proofs of concept available for this vulnerability. The urgency for defenders is to ensure they are running version 1.7.78 or higher to mitigate this risk.
Vulnerability Details
The official CVE description states that the vulnerability allows for a Mass Assignment issue within the settings management functionality of MyTube. Versions 1.7.78 and below are affected, requiring immediate attention from users of the application.
The CVSS score is determined to be 2.7, which indicates a low severity level. The vulnerability falls under the CWE-915 classification, which pertains to improper enforcement of security policies.
The vulnerability was published on January 24, 2026, and has been analyzed thoroughly.
Technical Analysis
The root cause of this vulnerability stems from the lack of validation performed on input data in the saveSettings() function. Attackers may exploit the system by sending crafted requests that include unauthorized property names, leading to unintended data being saved directly to the application's database.
The attack vector is classified as NETWORK, indicating that the vulnerability can be exploited remotely. The attack complexity is rated as LOW, which means that the attacker does not require advanced technical skills to exploit this flaw. The vulnerability requires HIGH privileges, limiting its exploitability to authenticated users.
User interaction is not required for successful exploitation, making it more critical. The confidentiality impact is NONE, while the integrity impact is LOW, indicating that unauthorized changes can be made, affecting data integrity. The availability impact is also NONE.
Risk & Impact Analysis
Organizations utilizing MyTube must understand the potential risks posed by this vulnerability. The ability for an attacker to persist unauthorized data directly into the database raises significant concerns regarding data integrity and application trustworthiness.
The blast radius of this vulnerability is considerable, as it allows attackers with high privileges to manipulate settings without adequate oversight. Organizations should assess their deployment for exposure to this flaw and prioritize it in their patching cycles.
Given the CVSS score and the lack of known exploitation, the urgency for organizations is moderate. However, organizations should schedule remediation as soon as possible to prevent any potential exploitation.

Ransomware Use | No |
Affected Versions
The versions of MyTube affected by this vulnerability are all versions prior to vendor patch 1.7.78. Users must ensure their systems are updated accordingly to avoid potential exploitation.
Mitigation & Remediation
Organizations should patch their MyTube installations to version 1.7.78 or higher immediately. If a patch is not available, consider implementing input validation checks to filter unauthorized property names before they are persisted to the database.
Additionally, configuration hardening should be undertaken to restrict access to settings management functionalities to trusted users only. Network controls can also be enforced to limit access to the application from untrusted sources.
For ongoing security, organizations may consider engaging in penetration testing to identify and remediate similar vulnerabilities.
Detection Guidance
Organizations should monitor logs for unusual access patterns or unauthorized changes in settings. Behavioral anomalies, such as attempts to modify settings by unauthorized users, should be flagged for further investigation.
Network signatures should be established to detect any unauthorized attempts to access the settings management functionality. Additionally, system changes that do not correlate with legitimate user activity should be closely monitored.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2026-24140 highlights the importance of input validation in application development. This vulnerability exemplifies how insufficient checks can lead to severe security implications, even in low-severity cases.
Security teams should note this pattern of vulnerabilities, particularly in applications that allow user-generated input. To mitigate such risks, robust input validation mechanisms must be integrated into the development lifecycle.
Overall, organizations should enhance their security posture by adopting best practices in application security. Engaging in regular security assessments and implementing a security testing strategy can significantly reduce exposure to similar vulnerabilities.
Additionally, integrating continuous security practices with a focus on application security can further safeguard against evolving threats.
