CVE-2025-15246 identifies a deserialization vulnerability in the aizuda snail-job software, specifically affecting versions 1.0 through 1.7.0 on macOS platforms. The vulnerability resides in the FurySerializer.deserialize function within the API component, where the argument argsStr is improperly handled, allowing an attacker to manipulate serialized data inputs. Deserialization vulnerabilities occur when untrusted data is processed by a deserialization routine, potentially enabling attackers to execute arbitrary code, escalate privileges, or disrupt service availability. This vulnerability can be exploited remotely without requiring authentication or user interaction, increasing its risk profile. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known exploits have been observed in the wild, the public disclosure of the vulnerability raises the likelihood of future exploitation attempts. The lack of available patches at the time of disclosure necessitates immediate risk mitigation measures. The vulnerability's impact includes potential remote code execution or denial of service, which could compromise system integrity and availability. Organizations using aizuda snail-job on macOS should assess their exposure and implement controls to mitigate exploitation risk.

For European organizations, the impact of CVE-2025-15246 can be significant, especially for those relying on aizuda snail-job for job scheduling or automation on macOS systems. Successful exploitation could lead to unauthorized remote code execution, allowing attackers to gain control over affected systems, exfiltrate sensitive data, or disrupt critical business processes. The partial impact on confidentiality, integrity, and availability means attackers could manipulate job execution, alter data, or cause service outages. Given the remote exploitation capability without user interaction or authentication, attackers can target exposed snail-job instances over the network, increasing the attack surface. This vulnerability could be leveraged in targeted attacks against enterprises, research institutions, or government agencies using macOS environments with snail-job installed. The absence of known exploits currently reduces immediate risk but does not eliminate the threat, especially as exploit code may emerge following public disclosure. Organizations in sectors with high macOS adoption or those integrating aizuda snail-job into their workflows face elevated risks of operational disruption and data compromise.

To mitigate CVE-2025-15246, European organizations should first inventory all systems running aizuda snail-job on macOS and assess network exposure. Since no patches are currently available, organizations should restrict network access to snail-job services using firewalls and network segmentation to limit exposure to trusted hosts only. Input validation and sanitization should be implemented where possible to prevent malicious serialized data from reaching the FurySerializer.deserialize function. Employing application-layer firewalls or intrusion detection systems to monitor and block suspicious deserialization attempts can provide additional protection. Organizations should also consider disabling or limiting the use of snail-job if it is not essential or replacing it with alternative job scheduling tools that do not have this vulnerability. Regular monitoring of security advisories from aizuda and prompt application of patches once released is critical. Additionally, implementing endpoint detection and response (EDR) solutions on macOS systems can help detect anomalous behavior indicative of exploitation attempts. Finally, educating developers and administrators about the risks of unsafe deserialization and secure coding practices will reduce future vulnerabilities.
