CVE-2025-24127 is a medium-severity vulnerability affecting multiple Apple products, including iOS 18.3, iPadOS 18.3, and macOS across several versions. This vulnerability allows an attacker to exploit improved checks within the system that could lead to unexpected application terminations. The CVSS score for this vulnerability is 5.5, indicating a medium level of risk, which organizations must not overlook.
The vulnerability exists due to improper parsing of files within the affected systems. Attackers may leverage this flaw to disrupt the normal operation of applications. Given the widespread use of Apple’s platforms in both personal and professional environments, the risk to organizations includes potential loss of productivity, disruption of services, and the possibility of data loss.
As of now, there are no known exploits in the wild, but the potential for exploitation exists, especially if the affected products are not updated. Organizations should prioritize patching immediately to mitigate any risks associated with this vulnerability.
The urgency for defenders to address this issue is high, given the nature of the vulnerability and its potential impact. Regular updates and vigilant monitoring are essential to ensure the security of systems affected by this vulnerability.
Vulnerability Details
The issue was addressed with improved checks, and it is fixed in iOS 18.3, iPadOS 18.3, iPadOS 17.7.4, macOS Sequoia 15.3, macOS Sonoma 14.7.3, macOS Ventura 13.7.3, tvOS 18.3, and visionOS 2.3. Parsing a file may lead to an unexpected app termination, which is classified under CWE-770.
The CVSS score of 5.5 indicates that, while the vulnerability is not the highest severity, it has a high availability impact, meaning it can cause significant disruption. The attack vector is local, and the complexity is low, with no privileges required for exploitation but requiring user interaction.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of file parsing within the affected Apple products. The attack vector is local, meaning that an attacker would need physical or remote access to the device to exploit this vulnerability. The attack complexity is classified as low, which means that exploiting the vulnerability does not require extensive technical skills.
No special privileges are required for an attacker to exploit this vulnerability, as it can be initiated by a user action, such as opening a malicious file. If successful, the attack can result in a high impact on availability, as it may lead to unexpected application termination. There are no effects on confidentiality or integrity.
Risk & Impact Analysis
Organizations using Apple products are at risk of application crashes that can disrupt workflow and impact productivity. The blast radius is significant, given the popularity of iOS and macOS devices in both personal and professional environments. This vulnerability’s medium severity score indicates that while immediate exploitation may not be evident, the potential for disruption remains.
Organizations should assess their exposure and implement necessary updates to mitigate any impact from this vulnerability. Considering the low user interaction required for exploitation, the urgency for addressing this vulnerability aligns with its CVSS score, necessitating prompt action to prevent potential disruptions.

For users of iOS and iPadOS, this means upgrading to at least version 18.3. Similarly, macOS users should update to version 15.3 or later, depending on their specific OS variant. If a patch is unavailable, organizations may need to implement configuration hardening and network controls to mitigate the risk.
Organizations should consider using penetration testing to ensure that all patches are effectively applied and to uncover any similar weaknesses in their systems.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor application logs for unexpected terminations or crashes. Behavioral anomalies, such as unusual application behavior following file parsing, should also be flagged and investigated. Additionally, network signatures indicating attempts to exploit this vulnerability should be tracked.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2025-24127 lies in the persistent challenges organizations face with application security. The pattern of vulnerabilities associated with improper data parsing continues to be prevalent in software development. Security teams should take lessons from this vulnerability by implementing robust file handling and parsing validation processes.
To stay ahead of potential threats, organizations can benefit from regular security assessments. This includes engaging in penetration testing methodologies that can identify critical vulnerabilities before they can be exploited.
Moreover, organizations should consider adopting a proactive approach to vulnerability management, ensuring timely patching and continuous monitoring of their application security posture. As technology evolves, so do the methods of attackers, making it essential to stay informed and prepared.
