This vulnerability allows for Cross-Site Request Forgery (CSRF) attacks due to insufficient CSRF protection and inadequate security attributes in authentication cookies within Bull's dashboard. Starting from version 12.109.0 and prior to version 2025.2.0-alpha.0, the APIs of bull-board are vulnerable, which could allow attackers to add arbitrary jobs, potentially compromising system integrity and availability. The vulnerability was fixed in version 2025.2.0-alpha.0, and it is crucial for organizations using Misskey to implement the patch as soon as possible.
The CVSS score for this vulnerability is 8.2, categorizing it as high severity. Risk to organizations includes significant impacts on availability and integrity. Attackers may leverage this vulnerability to perform unauthorized actions, making it imperative for affected parties to address this issue promptly. Organizations should prioritize patching immediately.
The vulnerability was publicly disclosed on February 11, 2025, and has been analyzed thoroughly. Although there are no known public exploits or proof-of-concept (PoC) available at this time, proactive measures are essential to safeguard against potential exploitation.
As a temporary workaround until the patch can be applied, it is recommended to block all access to the `/queue` directory using a web application firewall (WAF). This measure can help mitigate the risk while organizations prepare for full remediation.
Given the high severity and potential impact of this vulnerability, organizations using Misskey should take immediate action to secure their systems and prevent unauthorized access.
Organizations should validate remediation through penetration testing to identify similar weaknesses.
For further insights into vulnerability management, security teams can refer to additional resources and best practices available on the AppSecure blog.
As organizations move forward, understanding the implications of this and similar vulnerabilities will be crucial for maintaining a robust security posture.

Vulnerability Details
The vulnerability identified as CVE-2025-24897 affects Misskey, an open-source federated social media platform, specifically versions 12.109.0 up to but not including 2025.2.0-alpha.0. The issue stems from a lack of CSRF protection and inadequate security attributes in the authentication cookies of Bull's dashboard.
The CVSS score stands at 8.2, indicating a high severity level, with an attack vector classified as NETWORK. The vulnerability allows for potential compromise of integrity with a low impact on availability.
The full description of the vulnerability indicates that it could lead to serious consequences, such as the ability to add arbitrary jobs, thereby affecting system performance and reliability. This emphasizes the need for immediate attention from all users of Misskey.
Technical Analysis
The root cause of CVE-2025-24897 is the insufficient implementation of CSRF protection mechanisms within the Misskey platform. Attackers may exploit this vulnerability by sending unauthorized commands to the server on behalf of authenticated users, particularly through the bull-board APIs.
The attack vector is classified as NETWORK, requiring low complexity to execute. No privileges are required, and user interaction is necessary to trigger the CSRF attack, which adds another layer of complexity to the exploitation process.
The potential impacts are significant: while confidentiality is unaffected, the integrity of the system could be compromised, allowing attackers to manipulate job entries or system processes. Availability may also be impacted, albeit to a lesser extent.
Risk & Impact Analysis
The deployment risk associated with CVE-2025-24897 is considerable. Organizations that utilize Misskey without the necessary updates remain susceptible to CSRF attacks, which could lead to unauthorized job executions and significant data integrity issues. The blast radius for such exploitation could extend to all users and systems interfacing with the vulnerable APIs.
This vulnerability highlights the importance of implementing robust security measures, including CSRF protection and proper cookie attribute configurations, to safeguard against potential attacks. Organizations should assess their security posture and prioritize remediation efforts based on the CVSS score of 8.2, which indicates a high urgency for patching.
Given the active exploitation potential and the lack of public exploits, organizations must act swiftly to protect their systems from this significant threat. The urgency for patching this vulnerability cannot be overstated.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerability affects all versions of Misskey starting from 12.109.0 and prior to version 2025.2.0-alpha.0. Organizations running these versions should take action to patch their systems by upgrading to the fixed version 2025.2.0-alpha.0 or implementing the recommended workaround.
Mitigation & Remediation
Organizations should upgrade to Misskey version 2025.2.0-alpha.0 or later to fully remediate the identified vulnerability. If immediate upgrading is not feasible, it is advised to temporarily block access to the `/queue` directory using a web application firewall (WAF) as a workaround.
Additionally, implementing proper CSRF protection and ensuring that authentication cookies have the appropriate security attributes can further enhance security measures against this type of vulnerability.
Monitoring and logging access to the affected APIs can help detect any unauthorized attempts to exploit this vulnerability, providing an additional layer of security while organizations work on comprehensive remediation.
Detection Guidance
To detect potential exploitation attempts, organizations should monitor their logs for unusual access patterns, particularly around the bull-board APIs. Look for requests that may indicate CSRF attacks, such as repeated submissions from authenticated sessions.
Behavioral anomalies, such as unexpected job additions or alterations from user accounts, should also be flagged for review. Network signatures that identify unauthorized API access can further assist in detecting potential intrusion attempts.
AppSecure Threat Intelligence Insight
CVE-2025-24897 represents a significant gap in security for the Misskey platform, highlighting the need for continuous vigilance in application security. The lack of proper CSRF protection can lead to serious consequences if not addressed timely. As seen in this case, vulnerabilities related to authentication and session management are critical and often exploited by attackers.
Organizations should review their security configurations regularly and ensure that they are adhering to best practices for API security. This includes not only implementing CSRF protections but also ensuring that all security attributes for cookies are correctly configured.
For those looking to enhance their security posture, consider adopting a comprehensive approach that includes regular penetration testing. Such assessments can help identify vulnerabilities before they are exploited, ensuring a proactive stance against emerging threats.
To support these efforts, organizations can engage in continuous security testing to validate their defenses against known and unknown vulnerabilities, fostering a culture of security awareness and preparedness.
