GHSA-cggj-fvv3-cqwv FasterXML jackson-databind allows unauthenticated remote code execution

• Maven com.fasterxml.jackson.core:jackson-databind: >= 2.8.0, < 2.8.11.1 → fixed in 2.8.11.1 • Maven com.fasterxml.jackson.core:jackson-databind: >= 2.9.0, < 2.9.5 → fixed in 2.9.5 • Maven com.fasterxml.jackson.core:jackson-databind: >= 2.7.0, < 2.7.9.3 → fixed in 2.7.9.3 • Maven com.fasterxml.jackson.core:jackson-databind: < 2.6.7.5 → fixed in 2.6.7.5

FasterXML jackson-databind before before 2.6.7.5, 2.7.x before 2.7.9.3, 2.8.x before 2.8.11.1, and 2.9.x before 2.9.5 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 deserialization flaw. This is exploitable by sending maliciously crafted JSON input to the readValue method of the ObjectMapper, bypassing a blacklist that is ineffective if the c3p0 libraries are available in the classpath.
