Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 28 Oct 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate CVE-2024-44296, organizations and users should promptly apply the security updates released by Apple, including Safari 18.1 and the corresponding OS updates for iOS, iPadOS, macOS, tvOS, visionOS, and watchOS. Beyond patching, web developers should implement defense-in-depth strategies such as strict CSP policies with nonce or hash-based script allowances, and use Subresource Integrity (SRI) to ensure resource integrity. Organizations should educate users about the risks of interacting with untrusted web content and employ web filtering solutions to block access to known malicious sites. Monitoring web traffic for unusual script execution patterns and employing endpoint detection and response (EDR) tools can help detect exploitation attempts. Regular security assessments of web applications and browser configurations can identify potential weaknesses in CSP implementation. Finally, organizations should maintain an inventory of Apple devices and ensure timely deployment of patches across all endpoints to reduce exposure.

Description

The issue was addressed with improved checks. This issue is fixed in Safari 18.1, iOS 17.7.1 and iPadOS 17.7.1, iOS 18.1 and iPadOS 18.1, macOS Sequoia 15.1, tvOS 18.1, visionOS 2.1, watchOS 11.1. Processing maliciously crafted web content may prevent Content Security Policy from being enforced.

Impact

The primary impact of CVE-2024-44296 is the potential bypass of Content Security Policy enforcement in Safari, which can lead to the execution of unauthorized scripts or loading of malicious content. This can compromise the confidentiality and integrity of user data by enabling cross-site scripting (XSS) or content injection attacks. Attackers could steal sensitive information, hijack user sessions, or perform actions on behalf of the user within the context of trusted websites. While availability is not directly affected, the breach of CSP can facilitate further attacks that degrade user trust and security. Organizations relying on Safari for secure web access, especially those handling sensitive or regulated data, face increased risk of data leakage and compromise. The vulnerability affects a broad range of Apple devices, increasing the scope of potential impact globally. The requirement for user interaction limits automated exploitation but does not eliminate risk, particularly in targeted phishing or watering hole attacks.
