CVE-2017-17485: jackson-databind vulnerable to remote code execution due to incorrect deserialization and blocklist bypass

October 18, 2018 (updated March 1, 2024)

FasterXML jackson-databind allows unauthenticated remote code execution. This is exploitable by sending maliciously crafted JSON input to the readValue method of the ObjectMapper, bypassing a denylist that is ineffective if the Spring libraries are available in the classpath.
