Inappropriate implementation in PictureInPicture in Google Chrome prior to 145.0.7632.45 allows a remote attacker who convinces a user to engage in specific UI gestures to perform UI spoofing via a crafted HTML page. This vulnerability has been classified as medium severity with a CVSS score of 6.5, indicating it poses a tangible risk to users. Attackers may leverage this vulnerability to mislead users, potentially leading to unauthorized actions or data exposure.
The exploitation of this vulnerability requires user interaction, specifically through gestures that can be manipulated by an attacker. This indicates a moderate level of risk, as users must be convinced to engage in such actions. As a result, organizations should prioritize patching immediately to protect their users from potential phishing or social engineering attacks.
Given the nature of this vulnerability, it is critical for organizations to ensure that they are running the latest version of Google Chrome. Patching should be integrated into the organization's regular maintenance schedule to mitigate exposure to this type of risk.
For those managing systems using Google Chrome, awareness and immediate action are necessary. Regularly checking for updates and applying them can significantly reduce the likelihood of successful exploitation.
Vulnerability Details
The vulnerability described is categorized under CWE-451, which relates to "User Interface Spoofing." The specific affected product is Google Chrome, and the issue was disclosed on February 11, 2026. The vulnerability's CVSS vector is CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N, indicating a network attack vector with low complexity and requiring no privileges, but necessitating user interaction.
Technical Analysis
The root cause of this vulnerability lies in the inappropriate implementation of the PictureInPicture feature in Google Chrome. Attackers can exploit this weakness by creating a malicious HTML page that manipulates how the user interacts with the browser, specifically targeting UI gestures that the user must perform.
The attack vector is network-based, meaning that an attacker does not need physical access to the user's machine to exploit the vulnerability. Instead, they can initiate the attack remotely, provided the user visits the crafted page. The attack complexity is low, as it relies on user interaction rather than sophisticated technical skills or tools.
No privileges are required for the exploitation, making this vulnerability particularly concerning. Furthermore, the integrity impact is rated as high, meaning that successful exploitation can lead to significant manipulation of the user interface, potentially resulting in unauthorized access to sensitive information.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is moderate. Organizations should consider both the potential for UI spoofing and the likelihood of user interaction with a malicious page. Risk to organizations includes the possibility of unauthorized actions being taken by users who are misled by the spoofed interface.
The urgency of addressing this vulnerability is medium due to its exploitability requiring user interaction, but organizations should still act promptly to mitigate risks. Patching should be prioritized in the upcoming patch cycle to ensure users are protected against potential exploitation.
