Impact
Use‑after‑free in Chrome WebAppInstalls on macOS allows a remote attacker, by convincing a user to perform specific UI gestures, to execute arbitrary code with the privileges of the browser process. The flaw is a classic use‑after‑free violation (CWE‑416) and gives the attacker full control over the victim's system. The issue also maps to CWE‑825, reflecting an insufficiently controlled use of resources during web application installation.
Affected Systems
Google Chrome for macOS versions earlier than 148.0.7778.216 are affected. The vulnerability applies to the WebAppInstalls component used to install web applications directly from the browser.
Risk and Exploitability
The CVSS score of 7.5 indicates high severity. The EPSS score is not available and it is not listed in the CISA KEV catalog. Exploitation requires the victim to load a crafted HTML page and interact with it, meaning the attack vector is web-based. If triggered, the attacker gains arbitrary code execution on the user's machine, presenting a significant threat to confidentiality, integrity, and availability.
