CVE-2026-23848 is a medium-severity vulnerability affecting Franklioxygen's MyTube prior to version 1.7.71. This vulnerability allows unauthenticated attackers to bypass IP-based rate limiting on general API endpoints by spoofing client IPs through the `X-Forwarded-For` header. The ability to send unlimited requests to protected endpoints can lead to denial-of-service (DoS) conditions and potentially exploit other rate-limited functionalities.
The vulnerability has a CVSS score of 6.5, categorized as medium severity. This means it presents a significant risk to organizations using affected versions of MyTube. Given the potential for abuse, it is crucial for organizations to address this vulnerability promptly.
As of now, there is no known public exploit for this vulnerability, but organizations are advised to remain vigilant. The urgency for patching is clear, as attackers may leverage this vulnerability to perform malicious activities.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability and ensure the security of their applications.
Vulnerability Details
The vulnerability description states that MyTube, a self-hosted downloader and player for several video websites, is susceptible to a rate limiting bypass. Before the release of version 1.7.71, attackers could manipulate the `X-Forwarded-For` header to spoof their IP address, allowing them to bypass rate limiting on general API endpoints. This issue has been addressed in the latest patch.
The vulnerability is classified under CWE-807, indicating that it falls within the realm of security-related bugs. The CVSS base score of 6.5 reflects the medium severity classification, which is essential for organizations to understand the potential impact of this issue.
MyTube versions prior to 1.7.71 are affected, and users are encouraged to upgrade to the latest version to mitigate this vulnerability.
Technical Analysis
The root cause of this vulnerability stems from inadequate validation of the `X-Forwarded-For` header used in IP-based rate limiting. Attackers can exploit this flaw by injecting crafted headers to manipulate their perceived IP addresses, effectively bypassing restrictions intended to limit the number of requests from a single source.
The attack vector for this vulnerability is classified as network-based, and it has low complexity. Importantly, no privileges are required for an attacker to exploit this vulnerability, nor is user interaction necessary. The impact on confidentiality is low, while the potential impact on availability is also rated low, which underscores the need for remediation.
Risk & Impact Analysis
Risk to organizations includes the ability for attackers to overwhelm API endpoints, leading to denial of service conditions. This can disrupt services and affect user experience significantly. The blast radius for this vulnerability could encompass all users and services relying on the affected API endpoints.
Given the medium severity and the potential for exploitation, organizations should address this vulnerability in their priority patch cycle. The urgency for remediation is further echoed by the current lack of public exploits, indicating a window for proactive defense.

Affected Versions
All versions of MyTube prior to 1.7.71 are affected by this vulnerability. Organizations should ensure they update to the latest version to mitigate this risk.
Mitigation & Remediation
To remediate this vulnerability, organizations must upgrade to MyTube version 1.7.71 or later. Regular patching and updates are crucial to secure applications against vulnerabilities. Additionally, organizations should consider implementing network controls to monitor and limit the use of the `X-Forwarded-For` header.
For ongoing security, organizations can engage in penetration testing to identify other potential weaknesses.
Detection Guidance
Organizations should monitor logs for unusual patterns of request rates to API endpoints. Behavioral anomalies related to rate limiting should also be flagged for investigation. Implementing network signatures to detect attempts to manipulate the `X-Forwarded-For` header can further strengthen defenses.
