jackson-databind vulnerable to deserialization flaw leading to unauthenticated remote code execution

Description

jackson-databind in versions prior to 2.8.11 and 2.9.4 contain a deserialization flaw which allows an unauthenticated user to perform code execution by sending maliciously crafted input to the readValue method of the ObjectMapper. This issue extends the previous flaw CVE-2017-7525, blacklisting additonal vulnerable classes.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
