Chrome: Access of Resource Using Incompatible Type
CVE-2023-2935 is a high-severity access of resource using incompatible type vulnerability in Chrome from Google, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 114.0.5735.90 as the first without the flaw, so updating Chrome to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 23.9% chance of exploitation within 30 days, which is in the top 2.14% of all scored CVEs.
EPSS places it among the vulnerabilities most likely to be exploited soon.
What to do
- Update Chrome to 114.0.5735.90 or a later version.
- Read the advisory on chromereleases.googleblog.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
