Trend Micro Apex Central: Deserialization of Untrusted Data
CVE-2025-49219 is a critical-severity deserialization of untrusted data vulnerability in Trend Micro Apex Central from Trend Micro, 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 8.0.7007 as the first without the flaw, so updating Trend Micro Apex Central to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.52% chance of exploitation within 30 days, higher than 75% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Trend Micro Apex Central to 8.0.7007 or a later version.
- Read the advisory on success.trendmicro.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.

Official description
An insecure deserialization operation in Trend Micro Apex Central below versions 8.0.7007 could lead to a pre-authentication remote code execution on affected installations. Note that this vulnerability is similar to CVE-2025-49220 but is in a different method.

The underlying weakness: Deserialization of Untrusted Data
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
How developers prevent this class of flaw
- If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
- When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
- Explicitly define a final object() to prevent deserialization.
