Snapchat Lenscore: Access of Resource Using Incompatible Type
CVE-2024-5436 is a critical-severity access of resource using incompatible type vulnerability in Snapchat Lenscore from Snap, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 12.88 as the first without the flaw, so updating Snapchat Lenscore to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.52% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Snapchat Lenscore to 12.88 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Access of Resource Using Incompatible Type
The product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type.
