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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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 or the CVSS exploit maturity 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

Upgrade MobSF to version 4.4.5 or later immediately to ensure the vulnerability is patched.
Restrict APK upload permissions strictly to trusted and trained personnel to reduce the risk of malicious uploads.
Implement additional input validation and sanitization in any custom report generation or processing workflows involving MobSF outputs.
Monitor and audit upload activities and report access logs to detect any anomalous behavior indicative of exploitation attempts.
Educate users about the risks of interacting with untrusted reports and enforce policies to verify report sources before viewing.
Consider isolating MobSF instances in segmented network zones with limited access to reduce potential lateral movement in case of compromise.
Regularly review and update security testing tools and processes to incorporate vendor patches and security best practices.

Description

CVE-2026-24490 is a high-severity Stored Cross-site Scripting (XSS) vulnerability in MobSF Mobile-Security-Framework versions prior to 4.4.5. It arises from improper sanitization of the android:host attribute in Android manifest analysis reports, allowing attackers to inject malicious JavaScript by uploading crafted APK files. Exploitation can lead to session hijacking and account takeover within the victim's browser session. The vulnerability requires authenticated access and user interaction to upload the malicious APK, but it affects the confidentiality and integrity of user sessions with no impact on availability. MobSF 4.4.5 addresses this issue by properly neutralizing input. European organizations using vulnerable MobSF versions for mobile app security testing are at risk, especially those in sectors with high mobile app security demands.

Impact

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of user sessions within MobSF environments. Organizations that rely on MobSF for mobile app security testing, particularly those handling sensitive or regulated mobile applications, may face session hijacking or account takeover if malicious APKs are uploaded and reports viewed by authorized personnel. This could lead to unauthorized access to sensitive security testing data, manipulation of testing results, or further lateral movement within the network. The requirement for authenticated upload and user interaction limits the attack surface but does not eliminate risk, especially in environments with multiple users or less stringent access controls. The vulnerability could undermine trust in security testing processes and potentially expose intellectual property or compliance-related information. Given the growing importance of mobile security in sectors such as finance, healthcare, and government across Europe, the impact could be material if exploited.
