xray-monolith: Access of Resource Using Incompatible Type
CVE-2026-24874 is a critical-severity access of resource using incompatible type vulnerability in xray-monolith from Themrdemonized, with a CVSS 3.1 base score of 9.1 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 2025.12.30 as the first without the flaw, so updating xray-monolith to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.3% 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 xray-monolith to 2025.12.30 or a later version.
