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

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
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: None: The vulnerable system can be exploited without any interaction from any user.
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: 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: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

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.

What to do

AI-suggested

The primary mitigation is to update the TikTok Android application to version 34.5.5 or later, where this vulnerability is addressed. Organizations should enforce app update policies on managed devices to ensure timely patching. Additionally, restricting installation of untrusted third-party applications on Android 12 and later devices can reduce exploitation risk, as the vulnerability requires a malicious app to be present. Employing mobile threat defense solutions that monitor app behavior and detect anomalous WebView activity can provide additional protection. Developers should audit exposed WebView interfaces and implement strict deeplink validation to prevent traversal attacks. Users should be educated about the risks of installing unknown apps and encouraged to keep their applications updated. Network-level controls to monitor and block suspicious traffic originating from mobile devices may also help detect exploitation attempts.

Description

The TikTok (aka com.zhiliaoapp.musically) application before 34.5.5 for Android allows the takeover of Lynxview JavaScript interfaces via deeplink traversal (in the application's exposed WebView). (On Android 12 and later, this is only exploitable by third-party applications.)

Impact

This vulnerability can have severe consequences for organizations and individuals using TikTok on Android devices. Exploitation could allow attackers to execute arbitrary JavaScript code within the app's WebView context, leading to data theft, unauthorized actions, or app disruption. For enterprises, this could result in leakage of sensitive user information or compromise of corporate devices if TikTok is installed. The fact that no user interaction or privileges are required (except for third-party app installation on Android 12+) increases the attack surface. Given TikTok's popularity globally, especially among younger demographics and in regions with high Android penetration, the impact could be widespread. Additionally, attackers could use this vulnerability as a foothold for further attacks or lateral movement within compromised devices. The absence of known exploits in the wild reduces immediate risk but does not diminish the urgency for patching.
